Gabriel Luna as Corporal Dominic "Dom" Santiago

Gears of War Gabriel Luna

Known for: Marvel’s Agents of S.H.I.E.L.D.

Next to Marcus, the most important character in Gears of War is Dominic Santiago, the heart and soul of Delta Squad. Hoping against all hope that his wife Maria is still alive, Luna — who famously played Robbie, a.k.a. Ghost Rider in Season 4 of the Marvel TV series Agents of S.H.I.E.L.D. — has proved he can play tough and warm all at once.
