Jasper is a one-dimensional, poorly written antagonist with no redeeming qualities whatsoever, who bears similar qualities to that of the Hulk.
This page's purpose is probably not for copying and pasting over Jasper's bio on the Steven Universe wiki. Okay maybe it probably is.
In the hellish, lesbian-space-rock bonanza known as Steven Universe, Jasper is usually seen randomly appearing in front of one or more protagonists, where she then gets really mad and yells a lot. This in turn apparently develops one ore more of the characters present.
Personality and traits
She's a cunt.
That's her character.
