Looks about right, though tbh I've always imagined that Gren actually shaped more like a [url=http://image.bolterandchainsword.com/painter/blanks/smblank.jpg]Space Marine[/url] than an orc. I'm putting emphasis on his legs and ability to maintain rooted to his position so he can naturally withstand the sheer recoil of The God Eater without relying on his semblance (Being 300+ pounds buck nude helps). In sense, he is almost literally and figuratively built like a tank.

At some point when he stops trying to hide his cyborg nature, he may simply opt for tank treads for a faster charge and the sheer awesomeness of being a tank-centaur.

He usually tries to squeeze through or find another entrance. But yeah, that sounds about right. He'd just kool-aid man his way inside if he isn't worried about breaking stuff.
