Brainstorm hoards cats and they all love Percy partially to his dismay at times. He warms up to them and even gives in to calling them all the rediculous names Brainstorm gives them.
Every time Percy enters Brainstorm’s lab he has to shuffle his way through the sea of cats that have gathered at his feet to say hello!!!
They all crawl all over his stuff and when he gets mad they nuzzle him and he melts.
