While thinking about old movies and shows me an my cousin watched as kids, we remembered an animated movie that had a bunch of school kids who had this card game come to life. And no it was not Yu-Gi-Oh!.
In the movie, the characters and monsters in the card game the high school kids possesed started to come to life. The characters were anime characters and one of the boys had blue hair, and maybe was a prince of an alien planet in the game. I think an alien invasion started because of the cards and started abducting cows, turning them into monsters of sorts.
It was aired on either Cartoon Network, Nickelodeon or Disney channel. We watched it roughly 2012-2013 and I think the name had "Zero" in it.
