One of my submissions for the 8th evil ex contest (click to enlarge is recomendededed)
BEHOLD, TOX GRIM-PILL!
He's Scott from an alternate 'opposite' dimension, one year older and still a complete Tool. Tox Grim-Pill (scott pilgrim pronounced backwards) is one of Ramona's evil ex's in his alternate dimension. He's everything that Scott isn't, a tool! But after he was dumped by Anna Mora (yeah... ramona pronounced backwards : P) in his dimension he went insane with anger. When he couldn't go to Anna Mora, he went to science!
For a whole year he studied time and alternate dimensional travel. He built a machine that sent him to our Scott's world to take Ramona for himself! During his trip he gained powers that were based on his douchebag tool attitude and clothing. He has a lot of tricks up his sleeve, and a lot more gel in his hair to boot, but he's practically a dead even match for Scott.
For weapons he has collars... That's right, he has two popped collars and enough spikes in his hair to date a hedgehog. His collars were turned into energy spewing razor sharp blades that power his douche-bag kung-fu.
He also comes equipped with a tribal tattoo, chain wallet, crappy 21 and over wrist bands from mainstream venues, one of those expensively thick and huge leather band with silver watches and the chin scruff of a Yiddish grandma.
Good luck Scott! oh... and the other contestants!
