Boomer

Canon
Boomer is the blond-haired, blue-eyed member of The Rowdyruff Boys. He is Bubbles' male equivalent and evil counterpart and was originally created by Mojo Jojo. After being killed by the Powerpuff Girls' kiss of death, he was revived by HIM and was given a cootie shot to prevent the same mistake to be repeated. As opposed to Bubbles' color sky blue, Boomer's is more like a cobalt blue. His key element is "Snips". Boomer is the second in the Rowdyruff Boys. Boomer and his brothers were creations of Mojo Jojo. He shares many of Bubbles's physical traits, having short blond hair parted in the middle which flips outwards in a similar style. His signature color is cobalt blue. Like his brothers, he has a signature colored shirt with black stripe, black pants, and black sneakers. His "recipe ingredients" are Snips.

Sexuality
He is not shown to be in love with anyone. With Butch, he may be not that sexistic as Brick does. Brick was the one who was talking with Princess Morbucks the most, Boomer and Butch didn't say anything, they were just smirking, just like they didn't have anything to say about it. There is a chance that he could like girls, but for now it is not confirmed (I mean, they didn't say anything about it). It also depends on the person and on the ship the person ships. The person's headcanon depends on the person (and also gender) what they ship him with. If somebody ships a straight ship with Boomer then they will most likely not headcanon him as gay.
