[@Kronshi]I came up with a plausible plot thing for a future event. The basic idea is that Mars is actually an attempt by Homeworld to recreate a powerful Gem Warrior known as Tiger Eye, except this version was made to be without Tiger's weakness, which was Empathy and a dislike for fighting and war. He was a Gem made specifically for fighting, unlike most others(Bloodstone could bve aware of this project, or it could've been a secretive one). Also, Tiger Eye had dissappeared during the war, but he'll make a reappearance in the RP as either a part of that perma-fusion gem I told you about before or as a corrupted gem. 

Speaking of those, would Aqua even know about corrupted gems? They probably weren't a well known issue until after the war, if we're following the PTSD theory.
