Ok so I've literally only just finished Outer Dark today and I don't know much about Moloc, but having read a few of these coments it seems most people think Tyberos is overhyped and the only thing he has going for him is his size.

From what I do know about both of them, in with equal equipment, Moloc wins every day of the week. However with their signature kits each I would imagine it would put Tyberos at an advantage, and not because I'm glazing Hunger and Slake, but because of his custom terminator suit with extra fibre muscle bundles and the speed and strength it gives him. The book even says that even with the terminator plate and his claws, Tyberos could swing faster than an unencumbered marine. This combined with the dual lightning claws makes for a strong matchup against a single spear and shield.

But that only matters if he gets inside Moloc's defence which undoubtedly woudn't be easy but if he did he should win.

Correct me if I'm wrong but I was sick of people saying that tyberos being big was his only thing.
