Hopefully, after the next Reality Storm (Control Collars), our friend Darkstar here is going to learn the hard way that you should never steal candy from skeletons.
See, he is currently residing in the Repo! Manor in the Western District where Jack Skellington, the King of Halloween town lives also. Jack keeps a store of Halloween candy in a jar, however, he licks each piece before placing it in. Since Jack was previously infected with nanites from the Generator Rex universe, he's managed to pass them on in a rather unorthodox way.
Darkstar has unwittingly eaten candy tainted with nanites, and the little robots are going to be taking advantage of his vampiric nature by turning him into a bat EVO.
He's going to be a multi-eyed, prehensile tongued (probably venomous...paralyzation by licking, ick) furry bat EVO.
Similar to Bat God and Man Bat, here, but leaner, more eyes (two main blue ones, four or five other reds), and a nasty, Venom-esque tongue.
Also, a few tufts of fur on his head are his usual corn silk blonde while the rest of his body is covered in grey fur that matches his canon skin tone.
Tongue will sometimes have venom on it, sometimes not.
