Thunder Soul

MegaMan.EXE performs Double Soul with ThunderMan.EXE by sacrificing an Electric-elemental Battle Chip. In MegaMan Battle Network 4, he obtains it in the REd Sun Tournament after defeating ThunderMan.

Abilities

 * All electric and non-elemental Battle Chip can paralyze the enemy, which can create fun combos against the opponent. * In the anime, Thunder Soul also allowed MegaMan to utilize the Thunderbolt attack, which allowed lightning to strike enemies.
 * Charge Shot: ZapRing (an electric-elemental ring of 20 damage that is shot like a bullet)
 * Weakness: Thunder Soul takes 2x damage from Wood attacks. Also, the ZapRing, similar to Roll Arrow, is weak and takes a long time to charge, but the paralysis makes up for it.

MegaMan NT Warrior Axess
Lan and MegaMan become extremely overconfident because of their new Cross Fusion abilities. Chaud and Raoul dress up in disco villian disguises and send ThunderMan (also disguised) to fight MegaMan under the pretense that they are Darkloids. But when SwordMan.EXE attacks, they are both beaten badly. ThunderMan gives MegaMan his Double Soul and they manage to drive away SwordMan.
