Not all cards are included here. This lists mostly cards which have some applicable commentary. Also, I list only one variation of cards with sequential numbers.
This card negates all damage done to you that is less than 100. This is per hit, not accumulative, so it doesn’t matter how many hits you take that are less than that amount. If you suffer an attack that is over 100 AT, you don’t take the damage from that hit, but the aura falls and it can’t be replaced without using another card. So this card is a one-shot deal; however, many viruses can’t actually muster an attack that is over 100 AT, so it does make you near invincible against many things. Note though that if an attack would remove your Aura, the Aura will disappear even if you successfully block the attack.
This automatically deletes any enemy that has 100 HP or less. It has no effect otherwise. This can affect even shielded enemies.
This hits an enemy that is directly lined up with you. If you strike something with this cannon, that target is encased in a bubble, and the ChainBubl will go on to hit adjacent enemies as well (diagonal directions only). Anyone who is struck is trapped in a bubble for a brief time or until they take damage.
When you shoot this, a cloud moves straight forward. When it bumps into an object, an enemy, or the edge of the screen, it stops and blasts all adjacent squares with electricity.
This blast shoots straight forward, exploding when it either strikes something or hits the end of the field. The attack hits a 3-panel wide row. You can shoot this at the edge of the screen to hit enemies on either side of the attack, if they are in the last row.
Characteristics: Fire, Boomerangs
This ring goes forward all the way to the end of the field, then it reverses course and returns. Because of this path, it can actually hit enemies both on the flight out and on the return trip. Enemies that stay still can be hit twice by this, and enemies which move can potentially be hit more times than that, depending on the direction in which they travel.
This attack travels forward as waves along the ground. The attack auto-tracks enemies and can change directions once, which means it can veer off diagonally to chase after enemies. This makes it useful for striking an enemy without being lined up with him.
Characteristics: Aqua, Auto-Aim
This card automatically flings ice onto the nearest horizontal row that has an enemy or object sitting on it. The panels that are struck by this card turn into Ice panels.
When you use this, MegaMan disappears from the field and two Jammers appear on the two panels where you weren’t standing and shoot rapid-fire shots down those two rows. This attack lasts for a brief moment, then the Jammers vanish and MegaMan reappears. Because of this curious property, you can actually use this card defensively to avoid attacks if you time it correctly.
This attack flings you forward down your current row. Because this is a bodily attack, you can pierce enemy defenses with this. However, this card can also leave you vulnerable, and you might just fling yourself straight into an enemy’s attack.
This places a cube of junk on the field in front of you. When an enemy lines itself up with the cube, it will slide toward them and shatter.
This places a crystal ball on the panel in front of you. For as long as the ball lasts, it will shoot fireballs down all three rows randomly. Enemies can destroy the crystal ball early if they damage it enough. The ball will also disappear after a short span of time.
This attack drops Moai heads on all of the enemies on the field. Enemies that move quickly may avoid being damaged because they get out from underneath the attack fast enough.
Obtained From: GigaBase
This is the most useful of the PowerBombs because it hits a 3x3 area. You can make do with the lower versions of the PowerBomb until you get access to this one though.
The RdrMissil-series of cards are interesting. They each have a trigger and will strike any enemy that matches the conditions at the instant you use the card. Note though that enemies that move quickly may avoid being damaged. RdrMissil2 will strike any enemy with an even number for its tens digit, and as such, this is the most useful of them because you can just shoot the enemies with your buster to set them up for this card.
Characteristics: Aqua, Auto-Aim
This causes a multi-hit rain to fall on the panels where enemies are standing at the moment that you use the card. Note that this card does not continuously update its aim, but only selects its panels once, at the beginning of the attack. This means enemies that move may move out of the range of the attack (but they might also move back into it).
Characteristics: Electric, Homing
This sends out a small electric ball. This ball moves slowly, automatically homing toward the nearest enemy. If the ball moves too many panels without striking anything, it goes away.
This places a bomb on a random tile two squares ahead. After a 3-second countdown, the bomb will explode and hit everything on the field. Enemies can destroy the bomb before it goes off if they do enough damage to it, which makes the fact that you can’t determine where the bomb is placed a little problematic.
This is a 3-panel wide wave. If you shoot this from the center tile, you will hit all three rows. The wave shoots forward until it strikes something, in which case it stops. Objects on the field such as blocks will also stop this wave, possibly prematurely.
Note: All Japanese names are listed given name first, family name last.

Note: Hidden bosses are not yet listed here.
I will get to them later. All HP and AT levels are for the first time you encounter the boss and may not apply to subsequent battles.
He blows bubbles down the three rows. You can shoot them. If you get hit by one, it’ll capture you in a bubble for a few seconds. He can also send his claws boomeranging forward. They will each hit two different blocks on your side, on either side of the screen, so you have to stand in alternate corners to avoid them. And he can form a big wave which covers your entire side; block this.
He looks like a jovial skeleton in a robe with flashing lights on it and three colored spheres of flame with skulls in them around him. The flame spheres perform attacks that are similar to various Battle Card attacks. You can destroy the flame heads while they are attacking; doing so gets rid of that head for about 1 round or so. Crown Thunder can also call down lightning on three squares in a triangle around him. He blips around a lot, including frequently standing in the row immediately in front of your row, where most enemies don’t stand unless they are attacking, and where many of your attacks can’t hit (but swords can, even without locking on).
Cygnus blips from tile to tile, evidently trying to avoid being lined up with you, and can toss feather daggers onto a tile on your side. Just dodge to either side. His spin-attack dance involves him going down one row, then up the next. This still leaves you a tile where you can dodge. And of course he can send his duck lackies after you. You can destroy them in transit; aim for the white one.
This boss comes in two forms, but only the black one has HP. You can stun the white one with attacks, but you can’t harm him. Unfortunately the white one keeps getting in your way, and both of them can attack you. They can shoot fist-like attacks forward, or attack simultaneously by slashing two of the three squares on your side, one right after the other. If they hit, you are paralyzed briefly. And they can stand together to shoot lightning forward in a T-shaped formation that hits all three squares on your side, so block. You can also knock them out of this attack with a blow that does enough damage.
She blips around and can form speaker blocks on her side. Her basic attack involves her notes which fly forward from her speakers. Easy to dodge, but this stuns you if it hits. She can also snag you with a string that looks like a musical staff, and damage you for multiple hits. And she has another attack that can strike all three slots on your side, which means you either have to defend against it or knock her out of it. This attack confuses.
He moves back and forth along the back row slowly and sends fire and water forward from his two scales; they hit three panels horizontally, which might mean hitting your entire row depending on where he fires from. Block in this case. He can also shoot forward and spin around with his two arms; this hits all of the panels on the entire battle field (so shield yourself). Finally, he may drop weights of some sort that keep slamming down repeatedly on your side; you must move back and forth to dodge them. Libra’s weakness changes based on which arm is lower at the moment.
She blips around, and she can send multiple snakes down multiple rows. The snakes can be destroyed but it takes more than a few hits to do it. You can also dodge between them if you are quick, or knock her out of the attack entirely. And she can fire twin lasers straight forward. She also has a slither attack where she moves forward quickly and hits two rows on your side. Stand in the opposite corner to avoid this.
(He uses “Moowahaha” as a pun on the typical “Muwahaha” standard maniacial laugh.) Omega will comment that Taurus runs in a straight line so he’s easy to dodge. This is true enough; when Taurus hangs out in the back row, he will soon charge forward. He really telegraphs his moves so it’s easy to get out of the way unless you’re caught in the middle of doing an attack. He can also use an inverse T-shaped attack that hits all three panels on your side. Use your shield to get out of this one. He also punches on one panel on your side; dodge this one, don’t try to block it.
He blips around, and he can slash at you while standing directly in front of you. He can also slash similar to a WideWave so that it hits three panels, which might be all of the panels on your side depending on where he is positioned when he does it. And he can form three wolves on his side to attack you. You can destroy these.
For the viruses section, currently I’m listing only one variation of each enemy, unless I have specific commentary on another version. (The “G” versions are identical to their lesser-sized cousins except for HP and AT levels.) Also, not all viruses are catalogued here yet.
This thing moves around slowly, sometimes hiding in its cloud. You can’t hurt it while it is ducked down into its cloud. It will occasionally stop and attack by hitting the panels surrounding it with lightning.
These cannons shoot only while you are lined up with them. Some of the variations use bombs which can hit multiple panels, so in this case you may need to block instead of simply moving left or right.
These things blip around from panel to panel, then when they are lined up with you, they charge forward. Because this is a bodily attack, you can’t defend with your shield. You will need to dodge.
They look like fireballs with eyes and mouths and little hands. They constantly move around setting TimeBombs. The bombs only hit the tiles immediately surrounding them when they blow up, not all tiles on the field like when you use the card, so you can either block or dodge. Or you can destroy the bombs by shooting them. You can damage the DoomCount while it is holding a bomb, but once it puts it down, your attacks will hit the bomb separately.
A floating round eyeball. It moves around and when it attacks, it puts a targeting cursor on one of the panels on your side and then hits it multiple times. The Eyez rotates as it moves around, and you can’t damage it normally when its backside is facing you.
A tanooki with a leaf on its head. It seems to avoid lining up with you, but otherwise doesn’t appear to move much. When it attacks, it turns into MegaMan and uses a Battle Card such as a Sword. This is actually pretty cute.
A virus that looks like a manhole cover with a water ghost underneath. It ducks down under its cover and slides around, then pops up and makes it rain on the panel where you were standing when it began its attack (so move). This virus can’t be hit by most attacks while it is ducked down, which means it can only be hurt while it is attacking. Stand on a tile that is away from where you need to be to strike the virus, then when it rains, quickly move over and attack the virus.
This virus looks like a saw blade with four hands, two red and two blue. It moves back and forth to stay lined up with you and doesn’t take damage from normal attacks. Its black hole attack can damage you from wherever you are. It can also throw planets at you (no joke).
You can only hurt this thing with sword-type attacks. You can also kill it with its own weapon, the BlackHole card. Once you have deleted all the other viruses in the battle, just wait for it to start to attack, then quickly move to the side and then block to avoid damage while waiting on an appropriate card to come up. Note: Some Grabity variations are vulnerable to Poison panels despite the fact that they are floating, so you can also hack away at their HP that way.
This is a large robot-like virus with an axe. It hops around slowly and heavily. When it attacks, it jumps to a location and slashes with a 3-panel wide attack. You can block this.
A Roader, in reference to the classic series. It moves forward and back in its row, heading toward you and then away from you again. Not really difficult to deal with when you keep an eye on its position; however, because it is a direct-body contact attack, you cannot block with your shield, so you have to make sure to dodge out of the HotRoader’s way.
These things blip around, and then randomly drop blocks on the field, along with other things like chunks of garbage (which shoot toward you if you line yourself up with them) and TimeBombs.
Looks like a cross between an alien spaceship and a light bulb. They blip around, and when they attack, they shine the screen and blind you briefly. (A barrier of any sort will negate this.) They can also kick at you directly.
There are several variations of this thing, each one with an...interesting name. These “sing” (badly—it’s more like garbling than singing), causing effects while they are singing. The effects of the singing depends on the version of the virus you are dealing with. However, a LuPelvis affects only its allies; it does not affect itself.
Looks like a witch sitting on a crystal ball. It likes to hide behind objects on the field or other enemies, and will occasionally cast “spells” which appear to be various Battle Cards like Barrier, Recover, HolyPanel, and of course its own card, which is flames that come forward on two rows.
A little guy with two swords. It bounces around, then comes forward and slashes two or three times in a row. The McCleaver can move in-between slashes to realign itself with you if you move to dodge, so you have to keep moving to avoid it. Another way to avoid damage is to have an object, such as a block, in the tile directly in front of you, so that the McCleaver cannot reach you to attack.
These look like fire lizards. They move around randomly, then attack down the row in front of them.
The classic Met enemy of the Mega Man property. These little guys are armed with pickaxes; they first try to get lined up with you, then they slash, which produces a shockwave that travels forward. Some variations of the Mettenna can only be damaged while they are attacking because they hide under their helmets otherwise. When there are more than one Mettenna on the field at once, only one will move and attack at a time.
A round statue with a face. This rolls toward you, moving on diagonals as needed in order to head toward you. You can strike its base while it is rolling, but this does not appear to damage it. Aim for the head instead.
This looks like a statue with a sword. Any attack made while it’s in statue mode does 1 HP of damage (except for piercing attacks which do full damage). When you line yourself up with the MonoSword, it will turn colored and shoot forward to attack with a sword swing. During this time it can be damaged normally. If you have a rapid-fire buster, however, you can just buster it to death, because it doesn’t matter in that case that your shots are doing only 1 damage each.
It hovers up and down, making it hard to hit when it is in the air. When it attacks, it turns the straight line in front of it that it hits into grass. When it gets low on health it will get angry and will stay down on the ground, shooting repeatedly.
They move back and forth with their eyes covered, then when they attack, they shoot a sonic beam forward. Getting hit by one of these will give you various status effects, depending on the variation of the virus in question—the Peekaboo variation confuses you. You can block their attacks with your shield.
A bush that stands there looking around. When you line yourself up with it, it jumps upward briefly as if startled, then charges forward (rather slowly) and pokes at you with its spear.
It moves around, then charges forward and hits you with the horn-like apparatus on its front.
A volcano-like virus. It sits still, and occasionally shoots a blast forward that will explode into a three-panel attack when it hits something or the edge of the screen (which means the row that you are on). If the Rocky is in the center, then it will hit all three squares on your side. Block with your shield in this case. Note that Rockies will aim at objects that you place on the field (such as TimeBombs) instead of you, if there are any.
These crabs move sideways and shoot bubbles forward. Left to their own devices, they will send bubbles down all three rows. You can shoot the bubbles or dodge between them. The main problem with them is that their bubbles keep getting in the way of your shots. Shoot rapidly, or choose a Battle Card that can plow through all of the bubbles and hit the virus.
Watermelons on sticks. They shoot rapid-fire seeds straight forward at regular intervals.
These little droplets of water hop back and forth. When they attack, they turn red and slam downward, creating a wave that is 3 panels wide. However, if the Wibbledee is against the edge of the field when it fires, only two of the panels will be covered by its attack. You can block the wave. Notice that Wibbledees cannot be hurt while they are in the air.
These move back and forth, trying not to stay lined up with you, then they will stop and send out a sparking sphere that moves along the ground. This attack can automatically adjust its course to head toward you. Once it reaches your row, however, it can’t move sideways to get at you, so you’re safe if you dodge it that long. You can also block the sphere. It stuns you if it strikes when you aren’t defending.
