Fire Soul Episode Premiered In: Episode 7, "Electric Flower Garden!" Following Appearances: Episodes 10, 22, 37, 46 Activation: Fireman and Rockman find themselves in a pinch when in a battle against Plantman. Their desire to win the fight enables a Soul Unison to occur between them, and Fire Soul is the end result. It's odd to think that a Soul Unison could occur between two Navis who were once opposing foes. Special Attributes: Fire Soul is obviously very strong against grass type enemies (primarily Plantman and Needleman). Rockman's entire body pretty much becomes a weapon of flame! Gained Attacks: Fire Arm Disadvantages: The fire attribute is strong against grass types, but is enevitably weaker against water attacks.
