I decided to watch a little Zexal today, and what do I find: Finally someone who's worthy of calling Kaito their rival (no offence Yuma fans, but the skill gap between them is bigger than Kaiba's ego)
yeah... Jack actually had a good rival all the way through. pretty sad they didn't let arc-v Kaito and jack duke it out after Zarc was beaten, the episode just writes itself! And if they would keep up with Jack he would win, cuz in 5d's he's not lost a single standing duel
