I Don't Care If You Get Black or White

Welcome to another weekend of three gijinkas. This week's theme is Pokemon with more than one head. Today's gijinka looks surprisingly similar to the male protagonist of the 5th Gen games. His ability's name is even the names of the 5th Gen games (Although I originally intended it to reference a certain singer with a liquid nose). It's all purely coincidence, I swear:
Pokemon: Girafarig
Ability: Black Or White
Black Or White is an ability that allows the user to separate people (Including his/herself) into two halves, with one half containing an extreme attribute and the other containing an extreme of the opposite attribute. For example, a moderately intelligent person can be split into a genius and a doofus, or a slightly moral person can be split into a chivalrous hero and an evil menace. To differentiate the two halves, one person will have their clothing in the original color, while the other one will have the clothes' colors inverted (But the body will remain identical, right down to the fingerprints). Do not be fooled, however, because the colors only serve as a differentiator, a person clothed in black is not necessarily evil, and one coated in white is not necessarily righteous. Girafarig uses this ability to make his opponents easier to defeat (Note that when one half receives damage, the other half is damaged in the same area), and sometimes, to give himself an advantage in numbers (Though when he uses it on himself, he tends to go for negligible or trivial attributes, such as obsession with chocolate).
