 |
MYSTERY DATA These crystals represent treasure boxes essentially. Check them to see what they contain; they could be anything from zenny to Battle Chips. Purple Mystery Data must be unlocked with a Sub Chip before it can be accessed. |
 |
HPMEMORY When you obtain this, MegaMan’s maximum HP is automatically increased. You don’t have to use it first. |
 |
REGMEM This increases the size of your Regular Memory, which is used to store your selected Regular Chip. |
 |
SUBMEM This increases the number of Sub Chips you can carry at once. |
 |
EXPMEMRY This increases the size of your NaviCust Memory Map grid, allowing you to place more parts into it. Extremely useful; strive to get these as soon as you can. |
 |
MINIENRG Recovers some of MegaMan’s health from the subscreen. |
 |
FULLENRG Recover all of MegaMan’s health on the subscreen. |
 |
UNTRAP When you use this, you will eliminate any “the Mystery Data was a virus!” messages for the area in which you use it. Unlike the Unlocker, this does not need to be used per mystery item; use it per area instead. |
 |
UNLOCKER This is needed to access purple Mystery Data. Stand next to the data in question, then use the Unlocker off your subscreen. Save first, then you can reset the game if you get an item you don’t like. |
 |
SNEAKRUN For a time, you will not encounter any random virus battles while walking around. This does not work against all viruses; in some areas, you will still get into battle. Also naturally you cannot skip boss battles this way. |
 |
LOKENEMY Increases the odds that you will encounter the same enemy as the one you last fought. |
 |
SPINPINK I’m listing only one here, but all of the “spin” items allow you to rotate the blocks of the stated color on the NaviCust grid Tetris-style. Select the part, so that you are dragging it around on your cursor, then press L or R. |
Styles come in two categories, which are then mixed-and-matched for the final style. Rather than list each style combination, I list the categories that can be combined.
Style Type
 |
BUG STYLE Mastered by fighting while bugged (via the Navi Customizer). This one causes random effects during battle, some of which mirror the bugs you can get using the Customizer, and some of which are actually beneficial. Your HP might decrease, might decrease only when the Custom Screen is open, you might get all 10 chip slots open from the start of the battle, MegaMan might snap in a certain direction, or you might get a shield or your buster might increase in power. There are lots of different effects you could end up with, so using this Style is really a gamble. |
 |
GUTS STYLE This increases MegaMan’s Power rating, thus allowing his shots to do more damage. Also you get a rapid-fire feature with this style, where if you mash the buster button quickly, MegaMan will eventually begin doing an auto-fire attack for a few seconds. Note that your feet are nailed to the ground when he is firing, so be cautious in using this. Mastered by using the MegaBuster a lot. |
 |
SHIELD STYLE You get a shield with this one which will block the first hit that you take during battle, regardless of the amount of damage it would have done. Mastered by using defensive chips a lot. |
 |
TEAM STYLE When you are equipped with this style, you can place more Navi chips into your Folder. Mastered by using Navi chips a lot. |
Style Element
 |
AQUA STYLE MegaMan gains an Aqua-based attack and is weak against Electric with this style. |
 |
ELEC STYLE MegaMan’s charged attacks turn into ZapRings. These will paralyze enemies they hit. MegaMan is weak against Wood with this style. |
 |
HEAT STYLE MegaMan’s charged attacks turn into a three-column flamethrower. This can take multiple hits, but comes out slowly. MegaMan is weak against Aqua with this style. |
 |
WOOD STYLE MegaMan’s charged attacks turn into little tornados. MegaMan is weak against Fire with this style. |
Here is a list of a few of the NaviCust parts you can pick up and use. Find others!
 |
ALPHA Use this to see the little Alpha puddles in the floor during certain stages. |
 |
ATK+1 Raises your shot power by 1. Since these also affect the power of your charged shots, they are quite recommended. |
 |
BATTERY You have a higher chance of being attacked by Electric-type viruses. Has no effect in areas where Elec-types never attack you to begin with. |
 |
BLCKMIND Required for part of the plot, to get bad Navis to talk to you (and to scare the heck out of certain good Navis). |
 |
BLOCK This is the shield from the previous game that never really worked very well. Press B + Left on the control pad while getting hit to reduce the damage you take. |
 |
BRAKCHRG Some objects (such as shields) can only be damaged by using punch-style attacks. With this, you can damage them with just super-shots. |
 |
BUGSTOP If you have this on the grid, you can bug as many parts as you want, and you won’t introduce any problems (MegaMan will still say he feels “great” even if you didn’t follow the rules). Note that this does not stop the random bugs that occur from using the Bug Style. |
 |
CHARGE+1 Raises your charge rating by 1. This shortens the time required to charge. |
 |
COLLECT When you have this equipped, you are virtually guaranteed to obtain a Battle Chip after battle, no matter what your Busting Level happened to be. Note though that enemies which do not give chips will result in you getting “No Data” (literally) so this prevents you from earning Zenny from battles. |
 |
ENGYCHNG Required to consume chips to create fire or water. |
 |
FISH You have a higher chance of being attacked by Aqua-type viruses. Has no effect in areas where Aqua-types never attack you to begin with. |
 |
HP+100 Raises your maximum HP by 100. When you equip this, your actual HP value will not rise, so you will be left with less than max. When you take this off, your HP is clipped to fit in the new maximum if necessary. You can stack multiple HP-raising parts to give your Navi an insane HP level. |
 |
HUMOR Equip this and return to the overworld and press L. Only works while you are playing as Lan. |
 |
JUNGLE You have a higher chance of being attacked by Wood-type viruses. Has no effect in areas where Wood-types never attack you to begin with. |
 |
OILBODY You have a higher chance of being attacked by Fire-type viruses. Has no effect in areas where Fire-types never attack you to begin with. |
 |
PRESS Allows you to navigate narrow areas. Required for a lot of places. You may want to just leave this equipped. |
 |
SNEAKRUN This is like a permanent version of the SubChip item by the same name. It doesn’t affect the more powerful viruses however. |
 |
SPEED+1 Raises your rapid-fire speed by 1. |
 |
SPRARMOR If you’re equipped with this, you can’t be pushed around by wind and stuff. |
 |
UNDERSHT If you’re struck with a fatal blow, you are left with 1 HP instead, unless you were already at 1 HP, in which case you die. |
I was going to list every Battle Chip in the game. However believe it or not the load time for this listing became astronomical because the page size was so large. So instead of listing every chip, I list only the chips which have some particularly interesting commentary. So common chips such as Cannons are not listed. You can figure those out on your own. Also I tend to list only the first version of sequential chips, if the more powerful variations are identical except for an increase of damage.

AIRSHOT1 This is like a cannon, but it is weaker and pushes the target back one tile when it hits. |
 | | AT: 100 |
|---|
Number: 40
Appears In: MMBN3
|
AIRSWRD Like a WideSwrd, but this one will push backward any target that it hits who isn’t invulnerable to being pushed. |
 | | AT: 100 |

Number: 191
Characteristics: Auto-Aim
Appears In: MMBN3, MMBN4, MMBCC
|
ANTIDMG You have to activate this by using it during battle. Once it is active, the next hit that MegaMan takes will trigger the chip. MegaMan will toss down a dummy of himself to take the blow while leaping into the air and chucking three throwing stars. The stars are randomly aimed at any enemy on the field and each star does 100 damage. More than one star might hit a single enemy for multiple damage to that target. Not only does this chip auto-aim and do great damage, but it also saves you from that hit. Note that the stars might miss enemies that move extremely quickly. |
 | | AT: 60 |
|---|
Number: 92
Obtained From: Boomer
Appears In: MMBN3
|
BOOMER1 A boomerang flies out from your side, crosses the enemy side, then returns to your side. This hits the top and bottom rows, and the last tile of the middle row on the enemy’s sides. So basically there are only two tiles on the field which are not affected. |
 | | AT: 20 |
|---|
Characteristics: Aqua
Appears In: MMBN3
|
BUBBLMAN This chip is pretty straight-forward, and I mean that literally. It should be noted though that this is another multiple-hit chip, so don’t be fooled by the low AT rating. BubbleMan does a number of hits which can add up to decent damage. |
 | | AT: - |
|---|
Number: 162
Appears In: MMBN3
|
COPYDMG When used, this chip shoots straight forward and places a red circle on the first thing it hits. This circle acts like a targeting cursor. When you damage another enemy, the one with the target circle also takes damage. Note that this can be used to multiply damage onto that enemy. If, for example, you use an area attack that hits two enemies at once, you will get double the damage on the targeted enemy, once from the direct hit, and once from the reflected damage. The target circle only lasts for a couple of seconds, so you have to be very fast. |
 | | AT: ??? |

Number: 38

CUSTSWRD The higher your custom gauge, the more damage this does. However, once your custom gauge reaches full, the damage rating of the sword appears to plummet. |
 | | AT: - |
|---|
Number: 144
Obtained From: Trumpy
Appears In: MMBN3
|
FANFARE Places a trumpet on the block in front of MegaMan. For as long as the trumpet survives, it will play intermittently. While it is playing, MegaMan glows green and cannot be harmed. Placing this in the enemy’s side of the field can sometimes be helpful to raise its life expectancy. You can only have one “helper” active on the field at a time, so using another chip which places something on the field will destroy your trumpet. (This is true for all such chips.) The Trumpy will also disappear on its own after a set amount of time, but it lasts a good while. |
 | | AT: 120 |
|---|
Characteristics: Fire
Appears In: MMBN3
|
FLAMMAN Similar to the FireMan chip, but not as nice. This still hits an entire row, but since FlamMan fires onto the ground, it will not cross broken tiles (holes). |
 |
GUTSMAN1 GutsMan drops down and slams the ground, sending out a shockwave that covers the entire enemy field and cracks all of the tiles it hits. This cannot cross broken tiles. |
 | | AT: 80 |
|---|
Number: 58
Obtained From: Pengi
Characteristics: Ice
Appears In: MMBN3
|
ICEWAVE An undulating snowflake travels along two rows. This hits every block in the two rows that it covers. |

KNIGHT A knight jumps across the field in a row. Falls down holes. |
 | | AT: 130 |

Number: 131
Characteristics: Wood, Auto-Aim
Appears In: MMBN3
|
LANCE This one hits the rightmost column on the enemy’s side of the field. Comes out fast. Good for enemies which hide in the back to stay out of the range of your swords. |
 | | AT: 90 |

Number: 7
Obtained From: Volcano
Characteristics: Fire

LAVACAN1 This one’s like a Cannon, but comes out slower and is Fire-based. |
 | | AT: 120 |
|---|
Number: 103
Appears In: MMBN3
|
MAGNUM1 When you activate this one, the action pauses and target cursors begin rapidly moving across the enemy’s side of the battle field. Press A again to select a column. This is sort of like a slot machine. |
 | | AT: 90 |
|---|
Number: 121
Obtained From: Slimer
Characteristics: Aqua
Appears In: MMBN3
|
METAGEL1 These are fun. This is like an improved Area Steal. Three gels drop down on the left-most column of the enemy’s side of the field. They damage anything sitting on those blocks and, if the block is empty, steal the block and turn it into a tile for your side. The effect is basically the same as an AreaGrab but the damage is better so I’d recommend these over AreaGrabs. |
 | | AT: 90 |
|---|
Number: 124
Appears In: MMBN3
|
PAWN Places a pawn on the field. When you press the A button, the pawn swings a sword. |
 | | AT: 20 |
|---|
Characteristics: Wood, Auto-Aim
Appears In: MMBN3
|
PLANTMAN PlantMan winds every vulnerable enemy on the field with vines. The affected enemies immediately suffer three hits of 20 damage each. When PlantMan disappears, the enemies are left tangled for several more seconds, during which they take another two hits of 20 damage, plus they are immobile and vulnerable to your own shots. |
 |
PROTOMAN1 ProtoMan blips across the field, appearing on each column in front of every enemy on the field, or at least those not blocked by an object or a hole. He swings a WideSwrd at each foe, which means he can thus do damage to enemies on either side of each target as well. Each swing does 160 damage. |
 | | AT: 100 |
|---|
Number: 109
Obtained From: Metrid
Characteristics: Fire
Appears In: MMBN3
|
RNDMMETR This and similar chips place a wand in the tile in front of MegaMan. For several seconds or until the wand is destroyed, meteors will fall on the enemy’s side of the field. Each meteor does 100 damage, so you could potentially stack multiple hits onto a single enemy. |
 | | AT: 20 |
|---|
Characteristics: Auto-Aim
Appears In: MMBN3
|
ROLL Roll pops in, appears in front of an enemy, hits the enemy, then disappears and drops a heart that heals you. This is an auto-aiming attack which makes it useful against enemies that are hard to line up. Note that the damage rating of the chip is per hit; Roll does three hits for a total of 60 damage. Her heart heals for half that. |
 | | AT: - |

Number: 126
Appears In: MMBN3

ROOK This is like putting a block on the field. You can hide behind this to protect yourself from certain attacks. |
 | | AT: 100 |
|---|
Number: 118
Obtained From: KillerEye
Characteristics: Elec
Appears In: MMBN3
|
SENSOR1 The Sensors produce a KillerEye on the tile in front of MegaMan. This acts almost identically to the virus, except that once its laser is triggered once, it disappears. |
 |
SHOCKWAV There are several chips which produce this same sort of slash along the ground. It’s important to note that this slash cannot cross empty tiles (holes). |
 | | AT: 130 |
|---|
Number: 42
Appears In: MMBN3
|
STEPCROS Similar to a StepSwrd, but MegaMan slashes in a cross attack instead. I find this less useful than the StepSwrd, but it can be handy in some situations. |
 | | AT: 130 |
|---|
Number: 41
Appears In: MMBN3
|
STEPSWRD MegaMan blips two tiles forward (into enemy territory) then swings a WideSwrd and blips back. This is a good way to hit enemies in the back row with a sword. The tile that MegaMan hits will be the same tile on the enemy’s side as he was standing on your side. For example, if you were standing on the middle column of your side, MegaMan will hit the middle column on the enemy’s side, so this is an easy way to determine how to line yourself up. |

Number: 129

TIMEBOMB If the timer successfully counts down without the bomb being destroyed, this damages all enemies on the enemy’s side of the field. |

Number: 115
Obtained From: Totem
Characteristics: Fire
Appears In: MMBN3
|
TOTEM1 This interesting chip places a Totem on the tile in front of MegaMan. It fires a three-column flame, then the face turns around and heals you. |
 |
VARSWRD You have to do special key presses, such as a fireball motion on the control pad, to get this one to swing. I never bother. |
 | | AT: 80 |
|---|
Number: 74
Obtained From: Jelly
Appears In: MMBN3
|
WAVE There are several of these which are used primarily by the Jelly viruses. They hit all three rows, but once each section of the wave strikes an object, it disappears. So it will not hit an enemy that is behind another enemy or object. |
 | | AT: 40 |
|---|
Number: 61
Obtained From: Yort
Characteristics: Boomerangs
Appears In: MMBN3
|
YO-YO1 Fires a disk forward three tiles. The disk then boomerangs back to you. It can hit on the coming and going for multiple hits of damage, but MegaMan cannot move until the attack is complete. |
 | | AT: 20 |
|---|
Number: 55
Obtained From: Bunny
Characteristics: Elec
Appears In: MMBN3
|
ZAPRING1 When this hits an enemy, it freezes him in place for several seconds. During this time the enemy is vulnerable to attack. However it doesn’t appear as though you can get a BugFrag by defeating a frozen enemy, even if he was frozen at the right time during his attack phase. |
Note: All Japanese names are listed given name first, family name last.

LAN HIKARI Your typical fifth-grader whose best friend happens to be his Net Navi, MegaMan.EXE. He’s resourceful and isn’t afraid to get in over his head, which is often where he gets MegaMan as well. He is, though, just a little bit dense. |

 |
MEGAMAN.EXE Lan’s Net Navi and a skilled virus buster. Like all Net Navi, he is incapable of leaving cyberspace because he has no physical body, but he communicates with Lan through his PET terminal. MegaMan and Lan get along like brothers—both the good aspects and the bad. |

 |
MAYL SAKURAI Probably Lan’s closest friend outside of MegaMan.EXE, although he doesn’t acknowledge this fact. Mayl is a girl in Lan’s class who loves walking with him to school and just plain spending time with him. |

 |
ROLL.EXE Roll is Mayl’s Net Navi and, as a result, rather good friends with MegaMan.EXE. When called upon in battle, she has both offensive and healing capabilities. |

 |
EUGENE CHAUD Chaud is a Net Battler—a member of a group of individuals who have made it their purpose to use their Net Navi to combat Net crime. He takes his job very seriously and gets irritated by any unauthorized interference. |

 |
DEX Another of Lan’s classmates and the owner of GutsMan. He takes great pride in his Net Navi but in truth isn’t very good at fighting Net battles. |

 |
YAI AYANOKOJI This rich fifth grader has a lot of knowledge of PETs, or at least likes to think she does. She helps out Lan mostly by giving advice. |

 |
GLYDE.EXE Yai’s Net Navi is programmed to be calm and polite. |

 |
DR. YUICHIRO HIKARI Lan’s father and an expert in PETs (Personal Exploration Terminals, or sometimes just PEsonal Terminals). He is, technically speaking, the creator of MegaMan.EXE. |

 |
HARUKA HIKARI Lan’s mother, who is generally oblivious to what Lan is up to (or pretends to be). |

 |
WILY The leader of the World Three (WWW). A rather insane man who wants nothing more than to delete the entire network. |

 |
TADASHI HIKARI Dr. Hikari’s father, and Lan’s grandfather. This man was responsible for creating the Internet. |

 |
ANETTA An environmentalist wacko who is conned by Wily into believing that the ’Net is destroying nature. |

 |
MAMORU This boy is suffering from the same ailment that killed Hub (MegaMan). His father created the Undernet. |

 |
MR. FAMOUS He’s from the previous game, although you’d never guess it if you haven’t played it. |

 |
MR. HIGSBY Higsby loves rare chips, so he has opened a chip shop to turn his joy and hobby into his occupation. |

 |
MR. MATCH He’s turned away from his old days at the WWW...or has he? |

 |
RAY This man likes to use hypnosis to get his way. His Navi, naturally, uses the same tactics. |

 |
SEAN He once created the Net Mafia Gospel, but has reformed from his old ways largely because of Lan. |

 |
SUMIYAMA The host of the N1 Grand Prix. He works for the TV station and is very concerned about its ratings...almost to a fault. |
 |
TAKEO Not much is known about this man except that he loves animals and wildlife. |

 |
TAMAKO She runs a shop outside the Yoka inn and also enters the N1 Grand Prix. |

 |
TORA A boy much like Lan who loves to Net Battle. |
Note: Hidden bosses are not yet listed here. I will get to them later. Also note that HP and AT levels are generally for the first time you encounter the Navi and may not apply to subsequent battles.

BASS.EXE Bass has three main attacks. One is a simple sphere which shoots straight forward. Another hits all rows on your side; knock Bass out of this attack with a strong hit to put a stop to it, or dodge until it finishes. The third attack involves Bass striking the ground with his fist; he cracks and damages the tiles around the one he hits. |

 |
BEASTMAN.EXE Blips around, jumping often to your side to swipe at you. He could also dash diagonally. His chip attack involves a number of arms which fly across the screen, followed by his head. |

 | | HP: 1000 | AT: ? |

Appears In: MMBN3
|
BOWLMAN.EXE He throws bowling pins at you. No joke. Also sometimes he will place pins on your side, then toss bowling balls along a row. The pins can be destroyed but result in shrapnel when they are, so be careful. |

 | | HP: 500 | AT: ? |

Weakness: Elec
Characteristics: Aqua

|
BUBBLEMAN.EXE Moves up and down in the rear column. The hole in the floor sends out bubbles, some of which are filled with various water creatures which will fly toward you in specific patterns when the bubbles are broken. There is a lot of stuff flying around during this battle, and the bubbles leave BubbleMan well protected. BubbleMan himself will occasionally toss spears at you. |

 |
DESERTMAN.EXE DesertMan likes to hide behind things. He tends to form two rock heads and he hides behind one of them and hangs out there while rock hands attack you (they shoot forward like the Fishy virus). Also sometimes a block will fall on your side, hitting in a “+” pattern. You can destroy the rock heads to get at DesertMan, but the first blow you inflict on the Navi will cause him to dive under the sand and come up somewhere else, usually reforming the heads in the process. So make it a good hit. |

 | | HP: 600 | AT: ? |

Appears In: MMBN3
|
DRILLMAN.EXE DrillMan’s HP is relatively low because he is invulnerable most of the time. He has two main attack patterns. One consists of three holes which open randomly, one on each row, and drills come out of two, with DrillMan emerging from the third. While you can hit DrillMan in this state, it can be difficult because the drill on his head protects him from a frontal attack, so you must use a WideSwrd or something and hit him as he goes by. The second attack involves three holes which remain open for a time and repeatedly toss out drills. In this case you can damage one of the three holes (it’s random which one) to do damage to DrillMan himself. DrillMan will also drill out of the ground on your side, dropping rocks onto three tiles. |

Also Known As: FlameMan.EXE
Operator: Mr. Match
Weakness: Aqua
Characteristics: Fire
Appears In: MMBN3, MMBCC
|
FLAMMAN.EXE FlamMan fights with two candles behind him. The candles themselves are invulnerable, but you can shoot them to snuff out their flames. The flame regenerates after a few seconds. The color of the flame determines its effect: green makes FlamMan invulnerable, red causes FlamMan to regenerate HP, and orange produces fire heads that circle your side of the field. FlamMan attacks along a row, and sometimes his flames hit all three rows in front of him. (An AreaGrab can help you dodge this if you hide in the tiles on FlamMan’s side of the field. This also works against the flame heads that circle your side.) Sometimes it’s helpful to leave one of the candles burning if its effect does not hinder you too much. That way you don’t have to keep putting it out, and can focus more of your shots on FlamMan. A few MetaGel chips are useful for this battle. |

 |
FLASHMAN.EXE Blips from square to square. One attack hits the tile in front of FlashMan and the tiles on either side. Another is like a ShockWav. FlashMan can place electrodes on your side of the field which will paralyze you if you don’t destroy them before they go off. |

 |
GUTSMAN.EXE GutsMan can crack the blocks on your side, but this can be to your advantage if you use it carefully. Break a block to the very right of your side of the playing field and stand on the block just behind it, and GutsMan’s main attack will be unable to hit you (but you can still shoot at him when he is across from you). Just watch out for his rocket fist. |

 |
KINGMAN.EXE KingMan fights using chess pieces. The knight moves around on your side and causes ShockWavs; the pawns swing LongSwrds at you, and the rooks block your shots. The knight falls down holes so breaking tiles is one way to get rid of it. The others can be destroyed with punches or with the BrakChrg. Destroying chess pieces is not permanent but is still useful. |
 |
METALMAN.EXE Gears move slowly on both sides of the battle field, damaging you and blocking your path. MetalMan throws missiles from above onto the flashing tiles. He also chucks blades straight forward, and the blade changes directions, boomeranging back to him. |
