Ah, so AI controlled, eh?
How are you gonna make it NOT broken, then? You need to balance it! What's the downside?
Anywho... NEW FORMS! I likes formses...
Sacrifice a ranged chip. Megaman fuses with the chip (and its element) to attain X Soul. Charge shots now have three levels of charge: 5x damage shot, 10x damage elemental shot, and 20x damage elemental shot. Holding L or R and moving before the cust gauge is full will allow megaman to dash, skipping a panel in the field. Chips can be charged, but it takes as long as the 3rd level charge. However, charging the chips adds 20 to the chip's power. Doesn't work if chips darken screen, or if they have no power rating. Like all souls, once the emotion window counts down to 0, the soul is undone. However, as Megaman fuses with the element as well, if he is hit by an opposing element, he will take double damage.
Sacrifice a melee chip. Megaman fuses with the chip (and its element) to attain Zero Soul. Charge shots now have three levels of charge: Sword, Long Sword, and Katana, all of which are of Megaman's element. Hold down A when using a defensive chip and you'll charge it while using it (things like Barrier, Guard, Aura, etc), and you'll unleash the chips power in the form of a boomerang, dealing damage equal to its defensive power (or in the case of the guard series of chips, the attack power). When moving while holding L or R before the cust screen is full, Megaman will dash, thus skipping a panel when moving on the field. As Megaman absorbs the element, he is weak to the element's weakness. HOWEVER, he also takes half damage from what the element is strong against (ex: Heat Zero - Takes double from aqua, takes half from wood). Like all souls, Megaman reverts when the emotion window reduces to 0.
Sacrifice a Navi chip. In fusing with that navi, you BECOME that navi at the level of the chip (Normal for regular Navi chips, EX for EX navi chips, SP for SP navi chips. For Roll, V2 is EX, V3 is SP. DS is treated like an EX level chip.) Your customization remains the same, however you take the form of the navi chip selected. You get it's charge shot, innate benefits, and element. You ARE the navi... Like all Souls, lasts three turns.
Armor X Soul
Sacrifice the X Buster Chip. Similar to X soul, but there is an additional level of charge. When charged to the fifth level, damage is equal to the fourth level, but hits in the area of a spreader. Chips that do not darken the screen can be charged to a second level (taking as much time as to the fifth level charge), and will do double their normal damage. They will also take a new form, depending on their element. Fire will become flamethrower, Elec will become an electric beam, Aqua will become a bubbler, Wood will become a lance (range depends on position. Hits top on top row, side in middle row, and bottom on bottom row), Wind will become a twister (a la gyroman), Break will become a Rolling Shiel--I mean Armadillo type attack, Cursor will become a machinegun type attack, and sword will become a Fighersword type attack. Like Chaos Unison, lasts only one turn.
Omega Zero Soul
Sacrifice the Z Saber chip. The buster shot now has two levels of charge, the first doing 5x damage, the second doing 10x damage. A button now unleashes a sword attack, and can be charged to unleash a Z Saber attack (takes as long as the second level buster charge). However, because of this no chips can be used. Like Chaos Unison, it lasts only one turn.
X and Zero soul looks like Megaman fused with the two, just like the rest of the souls.
Armor X and Omega Zero Soul uses X and Zero's sprites instead!
Joke form time!
Sacrifice the Sigma Virus chip to use. Megaman becomes Sigma, but the Viruses change too. If one virus, virus changes to X. If two, Viruses change to X and Zero. If three, Viruses change to X, Zero, and Axl. If it's a liberation mission and there's four, then the Viruses become Harupia, Fafnir, Leviathan, and Phantom instead (only because I know not of any fourth candidate from X... C>). Enemy team then uses an auto-hit PA at the start of the turn. If just X, then GigaCannon3. If X and Zero, their equivalent to 2xHero. If X, Zero, and Axl, they do their equivalent to the Grand Prix PA. If the guardians, they do their equivalent of the Master Style/Cross PA. IF Sigma-Megaman is still alive, Sigma, having taken control of Megaman, has taken control away from you as well, and acts by AI against the enemy. He has access to all the chips in your folder, and will use them. The 'enemy' will also be AI controlled, and will act according to character.
