Wettam was MASSIVE, even for a krogan. While a Lieutenant, he was second-in-command of the Blood Pack forces on Omega.
Wettam was renown for his strength. He was stronger and faster than any known krogan ever to set foot in the Blood Pack ranks. He had no biotic abilities, he did not need them. Wettam was grounds for the potential candidate of a Krogan Super Soldier program, which he turned down because he thought of procedures used to enhance one's strength unnaturally was 'weak-minded'. Wettam was skilled in the use of heavy weapons as well. His strength was renown for being able to wrestle and elcor in hand-to-hand combat, and win.
