Witch and her near. infinite forms
Witch’s “real” real form is just a cloud of purple gas that can solidify into her canon form, with all of these being alternates she takes to better interact with her surroundings; she has no bones, no organs, no nothing, it’s (almost-her heart marking is her “core”) all just gas meaning
She shapeshifts
Being a supercharged version of Heat will do that
Anyways
Witch occasionally gives herself horns, this is never without some kind of decoration hanging from them and she loves surfing the Internet for new inspiration. Coincidentally is also the type of person who has about 20 homemade phone keychains that she has hit people with
She can take the forms of other experiments, but this is largely aesthetic even in regards to fighting experiments; Witch has no super strength and like Heat, is a wet paper bag in hand to hand combat, but she can fool people from a distance; is most known for taking the appearances of other 6-series and before Snafu, would use them to distract Gantu away from newly activated experiments. Frequently took Heat’s form just to disrespect Gantu
The “organ” on her head isn’t actually an organ, but a gem; she intentionally made it because she wanted a little resemblance to Heat, and because of Crystallene’s favorite gemstones being iolite. But overall whenever she does take an alternate form, she always does tend to end up a mix of Heat, Angel, and Reuben with a reversed color scheme. She herself doesn’t know why that’s a thing
In general Witch’s powers in my works are “magic” in that they’re scaled up versions of Heat’s abilities; Witch operates such a massive concentration of energy that the things she’s able to do are effectively magic (transmutations, reality-warping, spontaneous generation, etc. her possession abilities are in actuality a side effect of her main powers)-there is a cap on them in the form of limits on how much mass Witch is able to generate or take, but she’s still one of if not the most powerful 6-series, second only to Holio and maybe El Finn if not for his password. It is implied 627 has some of her powers because of the castle he makes in the anime, but it’s never been officially confirmed
The main bases for all of these designs were vampires and goats, which I felt would be good references given her powers and name
