One Punch Man

I will have to watch this one, I've been hearing good things about it. I may wait until quite a few episodes are out, waiting for new episodes each week can suck sometimes when you really get into an anime. ;)

I don't know that we'll ever actually see someone strong enough to rival him, at least in the traditional sense. Mind control/telepathy, etc. I can see giving him a challenge. It would kind of defeat the whole purpose of the show to give him someone strong enough to challenge him. That's kind of the whole dynamic of the character. Again, I mean that in the sense of raw strength. Reality warping, time manipulation, and other larger scale powers that could nullify raw strength I can see being introduced, but I doubt anyone will ever challenge him raw strength vs. raw strength.
