Big meaty Proletariat Batman
In this issue he beats off a bunch of white supremacists
Here is the link to the annual issue, its a standalone story so if you want you can start with it
The first story is written and drawn by Daniel Warren Johnson, he made a really good transformers comic here is a link to issue 1
Everyone is constantly referring to him as huge so it's definitely diagetic, but it's stylistically exaggerated at moments of high tension and action
that explains a lot actually, yeah he definitely looks more like just a big guy in the non-action scenes now that I've read some, it's just in the thread image he looks like fuckin' dr mundo
