Authors Note: this is just a fourth and final Beastling traitor that I know will be used in the actual story (other than that, I will not say anything else of this upcoming chapter of Ultimate Team). Well, on with the description!
Disclaimer: Alvin and the chipmunks and The Chipettes belong to Ross B. and Fox Studios, and the story of Ultimate Team belongs to MetalMunk15.
Creature Designs: Wheatley the Mimic.
Named after the character of the same name from the videogame Portal 2, Wheatley is a formidable foe, and oddly enough is not the moron that his namesake is known to be. Wheatley is unique, in that he is fully aware of whom and what he is, no matter how long he stays as a copied person, and when mimicking someone he has not only a silvery patch on the back of his neck, but a couple patches above his eyes.
The amazing thing about him is that he has a heavy British accent to his voice, whether or not he's mimicking someone, which can come across as either the normal person acting weird or…well it can also give him away. Along with this, he's also able to mimic objects and even camouflage into his surroundings like a chameleon.
One thing to note is that, although he's a traitor of the Beastling Army, Wheatley doesn't intend to fight against them, he only left because he found it boring in the army. Since his leaving the army, he's been known as a prankster, and his pranking skills are enough to rival Alvin's (and that's like saying he's stronger than superman).
Once he joins the Ultimate Team, he uses the form of Alvin's alter ego "Machine" for public relations. When at the home base, he just takes his true form, which is about the size of an adult chimpanzee, with feet that have only three gripping toes, and his hands have only three fingers. He has a tail, though it's short and more of an extension to his tailbone. Wheatley's skin is slightly slimy to the touch, and he has the slug-like eye stalks on his head, allowing him to peek around corners and even look behind himself. Personality wise, he is similar to his namesake character in his mannerisms (fumbling with his words, and somewhat of a coward).
So, how's this guy? Let me know in the comments. Oh, and before I forget, Portal 2 and any references to its characters belong to the Valve videogame company.
