Proto Soul

MegaMan.EXE performs Double Soul with ProtoMan.EXE by sacrificing a Sword-elemental chip in both MMBN4 and 5.

Abilities

 * Charging a non-dimming Sword chip will cause MegaMan to warp 2 steps forward before executing the chip attack at double damage.
 * Also, MegaMan gains the Reflect program, but it overrides all other programs that use the B + ← combination. It deals 50 damage per reflect.
 * Charge Shot: WideSword (a regular WideSword that deals out 80 damage and in MMBN5, gains a 10 damage power boost for any additional levels to the Buster Power)
 * Bosses to use against:
 * ProtoMan.EXE: When he teleports to your area to attack, slice him.
 * ShadeMan.EXE: Same as above.
 * Weakness: The Proto Soul does not allow Program Advances to be charged, but most of the P.A.'s don't need it anyways. Also, the StepSword can leave MegaMan open to a Slasher, and any direct contact while using StepSword on an enemy will leave MegaMan injured. Also, Like Guts Soul, Proto Soul is very limited in range when it comes to the charge attack.

Chaos Soul
MegaMan's Charge Shot becomes a Dark Sword attack, hitting a 3 x 2 space for 400 damage in a fashion similar to the Life Sword Program Advance.

MegaMan NT Warrior Axess
MegaMan gains this soul during the battle with ShadeMan.EXE. As they are being pummeled by him, ProtoMan gives him the Soul to help him survive the battle as ProtoMan is too badly weakened by the Dark Chip to help. He uses this form to defeat Dr. Regal while he is Cross Fused.
