History[]
When a Gem named Rose Quartz gave birth to an offspring whose name as we know it is Steven Quartz Universe, and then Rose Quartz DIED because of some reason that the creator of the show, Pedo Bear, wouldn't tell us because of an experience working with the creator of Adventure Time. Anyway, Steven is yet to discover his inner gem powers. All he can seem to do is summon a shield for a few seconds at a time. Every time he discovers his new power, he would use it for fun then he will eventually end up in trouble. It's a cliche.
Steven later gets killed by Ron at the beginning of the DeviantArt War. Steven respawns after that, because he's a Mary-Sue. Sometime later, he turns into a giant monster and kills people. After turning back to normal, Steven is forgiven, even though he should be in WaJail for his crimes. So Bob Saget took matters into his own hands and sentSuper 17 to kill him Stevens gem was ripped out before being turned to ash by Super 17's Full power energy wave. Steven is now rotting away in Hell for being a mary sue
