MegaMan NT Warrior

Asteroid MoltanicMan was given to a criminal, but after an incident, a war-torn MoltanicMan drifts through the internet and finds himself in the PET of young fireworks-maker Fyrefox. Fyrefox is delighted to have a NetNavi after the loss of his own, and Fyrefox's friendship gradually sways MoltanicMan away from evil. However, MoltanicMan's original NetOp reappears, unwilling to give up his partner in crime to Fyrefox.
