[What? There's no aura or hidden form going on here. WombatMan actually changes his data configuration for these forms. With the aid of the NaviChip, he doesn't need to gather BugFrags anymore to do so.]
"Battle Chip, Slot In! Area Steal!" WombatMan quickly teleported away as the chainsaw struck. "Battle Chip, Successive Slot In! Sword, WideSwrd, LongSwrd! Program Advance, LifeSwrd" The LifeSwrd took the place of WombatMan's right arm, and he slashed rapidly with the blade. Taylor and WombatMan had just achieved Full Synchro. They moved as one, thought as one, breathed as one. "Battle Chip, Successive Slot In! FireSwrd, AquaSwrd, ElecSwrd, BambSwrd! Program Advance, ElemSwrd!" The ElemSwrd took the place of WombatMan's left. He savagely attacked his foe with the two blades. "Battle Chip, Successive Slot In! StepSwrd, HeroSwrd, StepCros! Program Advance, EvilCut!" The two blades resonated, and detached from WombatMan's arms, meeting above him where a third one was being created. There was a bright flash of light, and when it vanished, the new blade was in WombatMan's hands. It had no name, for it had no need of one. WombatMan smirked. "Feelin' lucky, punk?"
[Yes, I just made a PAPA. It is the father of all Program Advances.]
