Also for those who it may concern, when I do get around to writing up Gren's history, he is essentially Robo Cop with Captain America's backstory: Someone who wanted to fight the good fight, ended up getting mortally wounded for it, given the chance to try out an experimental procedure to turn him into a cyborg, and used as a propaganda machine while also being a war machine. And a sorta effective one, at least in Vacuo.
