Hello, I'm making some custom voyager/leader combaticons and I need help finding some suitable heads for each figure. Onslaught is the only leader class figure so the rest are voyagers. I want to know who's head would work for what character. Also, the heads would be for the marvel crossovers figures so keep that in mind. Thank you. Update: I already have Blast off's head so you don't need to worry about that.
