SuperMansion: Season 1, Episode 8

1 - 8: Brad Medicine

It turns out Brad is not a natural-born superhero like Rex, but instead is the result of an experiment at Optocorp, a combination of real life "evil" corporations and Oscorp from the Marvel universe. Brad is the first and only subject to survive the administering of their serum. It increases his size and strength, and makes him virtually invulnerable. The only thing that didn't increase in size is his head. Oddly enough, it is not the serum that makes him pink, it is just his natural coloring.
