Fire Soul

Game
Fire Soul only appears in MegaMan Battle Network 4:Red Sun. MegaMan acquired the ability during the DenDome tournament after defeating FireMan.EXE. MegaMan.EXE performs Double Soul with FireMan.EXE by sacrificing a Fire-elemental Battle Chip.

Abilities

 * By charging a fire-elemental Battle Chip, the chip becomes a FireArm that extends across the entire row with a damage of 50 + the Battle Chip's power.
 * Also, when the Double Soul is activated, some panels are changed to Grass panels (in a + pattern on each side) and MegaMan can recover on Lava panels.
 * Charge Shot: Fire Arm (Covers the 3 panels ahead of MegaMan, dealing 50 fire damage)
 * Weakness: Fire Soul takes 2x damage from Water attacks.
 * Bosses to use against:
 * VideoMan.EXE - The Fire Arm Charge Shot and Chip Charge attacks can pierce through both lengths of film at once which would otherwise result in a wasted attack.

Anime
Along with the respective navi, FireSoul is referred to as Torch Soul in the anime. During a battle with PlantMan.EXE, HeatMan is restored to TorchMan who gives MegaMan Fire Soul. MegaMan proceeds to delete PlantMan with it.
