I think in either Guardians of The Galaxy or in the Avenger's you could possibly introduce Eros, Thanos brother. I could maybe see Matthew McConaughey playing Eros depending on what type of character it is. Maybe Leonardo Dicaprio. Oh, is Starfox Starlord's father? Thanos and Eros don't always sea eye to eye. Both have ancient origins. Starfox is Eros.
