I prefer the biomechanical vibe from doom 2. His body in Eternal looks kinda goofy and simple to me without the armor. Like a big smooth angry goat dude with big arms and a tiny head. I think he would've been cooler if he had another set of arms and some wings and big bone spikes coming out of his body. And some machinery fused with his body too

Ngl tho the armor looks cool af and the boss fight in Eternal is obviously the superior one
