This was the greatest episode of the whole series.This is the whole reason why I watch this show.And why Billy is my favorite character.This episode had great action and we finally learn Billy's past as one of the invaders.And he was their leader.Until he gave it up.He joined the Center and became the Billy we know today.So then later he has to turn into Ganthar even though he does not want to.He destroys those stupid invaders,which I thought they'd never leave.And he saved the world.Before watching this I thought Martin Mystery was the most stupid show in the world but after this,I loved it.And I loved Billy too.Except for those idiot aliens hurting poor Billy,this was a great episode.
