Cinderblock

Cinderblock is a humanoid concrete monster. It's unknown who he was before his transformation, or even if he's human - though it is suspected he is human and was somehow transformed into the behemoth he is today. A very formidable enemy physically, he is usually hired as muscle for different groups. He's been shown as capable of taking on and beating several members of the Titans simultaneously - in a group that included Beast Boy, Wonder Girl, Bombshell, Aquagirl, Cyborg, Raven, Robin and Static.
