Ben 10 vs Danny Phantom isn't a rivalry at all.

Cartoon Network vs Nickelodeon is a rivalry. Just because the companies are rivals doesn't make their creations rivals. That would be like saying Dexter, Boy Genius vs Spongebob Squarepants is a rivalry because CN vs Nickelodeon.

The only connection Ben and Danny have is "teens who can transform", which isn't a good connection at all. Danny should face Jake, and Ben should fight... anyone else that isn't Rex or Danny.
