@Stryzzar, There are quite a few new characters I would've replaced with TD characters since they feel like rehashes.

@King Flurry51, Actually, the reason why Leonard is in this is because:

1. They wanted a magician character but decided "He was just as good" making him a last minute addition.

2. Cost cutting in order to save money on animation.
