Hi Chris! I don't mean to overstep my bounds, but that Hulk Yoga comic was reblogged without any credit whatsoever. It was originally done by Maris Wicks, who has a tumblr! (The URL is exactly what you would think it is.) The artist did not post that piece on its own, but they did reblog it here: post/82439616861/batmanfights-this-is-by-maris-wicks-whose-name. I hope this is helpful!
All fixed! I hope. As an artist myself I would have never done that willingly. I’m just not that internet bright. But YOU are! You didn’t overstep any bounds and for being awesome like that please accept this golden nibbles:
