when i was a kid i played the fuck outta this but i was curious what the online mode was like for this game and i lost my first online battle ever and apparently there was a feature where you could either spare, steal, or execute the loser's invizimal, and the guy that beat me decided to execute my #1 favorite invizimal and permanently delete it from my game. never played it again after that and i was so mad i broke my psp camera.
