Also, let's be honest, Bakugan was straight shit as a game. I know the entire point of the games were just to be toys but Bakugan was some next level bullshit. You literally just won by having a guy with more points than the other. You had cards to modify the points but nothing else changed. It had 3 mechanics and the only reason they continued to exist is because they were hella fucking cool when they worked, literally no other reason.

ALSO, all the main characters except for Dan canonically abandoned their partners the LITERAL SECOND it was more advantageous to have new ones.
