MegaMan NT Warrior (2002)

Season 4: Episode 1

BubbleMan, who was frozen in cyber space by Colonel, finds himself freed when a strange energy appears before him. Left behind is an infant NetNavi. He carries it to NetCity before collapsing and being found by Roll and the others. Meanwhile, strange disturbances appear in the real world as two gigantic cloaked beasts begin battling. Lan, Chaud, and Raika intervene, and the beasts move their battle to the internet. When MegaMan battles with them, the infant's power combines with his own, and MegaMan defeats the beasts using two new styles modeled after the beasts.
