Okay, here we go.
The concept of mixing Striker and the Glam Sisters was born from seeing a lot of fanart of Striker but it was either with the IMP crew or with characters that didn't make much sense for him to interact with. There's no background on this guy, so not a whole lot to build off of.
I thought of him interacting with the Glam Sisters not just because they're both sets of antagonists, but because of his first appearance, he had a flair for entertainment and performing. He seems to enjoy being the center of attention.
That was all I needed to make a story connecting the two.
