I like to read and participate in battle scenarios on sites such as Comic Vine or the r/whowouldwin Reddit sub, and every so often there's a post asking which character could compete with X character, and I can almost always say Ben 10 and probably be right. I mean, he survived universal erasure and also took the force of the entire universe, and in the same episode absorbed what was basically equivalent to the Big Bang and shot it!
RE: Is it bad that I think Ben 10 is one of the most powerful fictionals in mainstream?
