Negative Glacier

A Zoroark going by the name of Wrath Reginatto created this clone.

Originally Wrath was just a mysterious Zoroark with dark powers who despite dying countless times, would always return from the dead. He eventually became paranoid, wanting it to stop, so to ensure his safety, he revealed his scientific prowess in the form of creating the Negatives, which are clones of his fellow friends, such as Glacier, Savage and Flux. Glacier of course is one of his long-time faithful partners that looked out for him, as well as namely the Guardian of Unova. The prototype for this Negative was a lazy and uncaring slob, as the Negatives were initially opposite versions of their original counterparts. But after the first tweak to her this changed, but not for the better, as she was very lusty and obsessive of others, but she was no longer lazy and was quite active. This disturbed Wrath, so once more she was worked on, but this third change was what took the cake as Wrath's big mistake. She was an idiotic and abusive Glaceon complete with insane strength. After the ordeal with Wrath (See Negative Flux for more info,) she went outside at one point to be confronted by Negative Flux, who manipulated her into siding with him. Negative Flux takes her to his lab where he conducts his own experiment, and the result was granting her a strange power. This power gives her the ability to feed on the fear of nearby creatures, making her bigger and bigger the more she gets. This drove her to become just about everything her each and every adaptation had to offer. Lazy, dumb, super strong and abusive, but now with her size, she can become so big that she can consume Pokemon whole, where they wait for their inevitable death from being digested, if not coughed up of course. Her digestion takes a while to even begin, as her stomach is initially hollow, this is to let her savor her prey.
