The Nick cartoon made Rocksteady into a Russian general, and the movie Sheamus version said he was Irish (I think?).

IDW's Rocksteady just seems to be a standard white guy. But what about the OT's?

Do you think he also looks like Russian in the original cartoon? Or an American born Russian?

the movie said he was finnish.
And the ot rocksteady just seems like a dumb white dude.
