Jet Steven Universe

Jet use to work for Blue Diamond before leaving Homeworld because of the war but instead of fighting or picking sides she just up and left for no reason other than just thinking it was a stupid war and being a powerhouse she knew that homeworld would not track her down because of her brute force size and strength that even rivals fusion gems power to.

She fled to a small uncharted island hidden within the Bermuda Triangle where she became the local goddess and over time the one who made there home safe and five times more advanced than the whole world.    

People who go there by flying into the Bermuda Triangle don't go missing they just never leave because of the advanced tech and futuristic style and way the place is and apparently it is literally heaven on earth! 

Her weapon is A giant broadsword that only she can lift because of the density of her blade and she can dual wield to for a short time with incredible strength and speed but she has a flaw.

Even though she is faster and stronger then most (if not all) gems here boddy is very low in defence meaning she has speed and power but her body has a low durability problem and can easily get hurt as a result of being hit to many times in combat.

As for her personality she is actually quite loving and gentle when you get to know her but cross her and well lets just say they were right when they said the earth was once one whole continent before an impact split them up.
