Stickywicket is pretty simple, she’s the first one I thought of. Her entire body is made of sticky bubblegum, which allows her to leave any who try to fight her stuck humiliatingly to the ground. She enjoys wrestling, pranks, sugary candy, and laughing at others’ expense (usually as they’re helplessly trapped in gum). She’s infamously unruly, with Ex often needing to resort to threats to reel her back in when she gets too excited. She can leave pieces of her gum body as traps, and grow it back by eating sugar. She can also pull off comical maneuvers like inflating her head; her body is capable of stretching but it won’t snap back like rubber so it usually isn’t a good idea. She’s vulnerable to getting frozen.
 
It’s honestly not hard at all to take Pinkie’s character and turn it into a villain, she’s like 90% there already. You can take all the shitty things she does and just make it actual villainy and it works great.
 
Oh also, Stickywicket’s costume is supposed to be based on a gum wrapper, but I’m not sure how well it came out.
