Leo from another timeline

Leonardo had been raised by Draxum turning him into a fighting machine, Leo and Raph, Mikey, and Donnie met again on a mission. Mikey liked him since he would be biologically his brother (according to Mikey), Raph disliked him because of his selfish and proud attitude, Donnie didn't care as long as he wasn't near him. And there you come in, you were a friend of April and Raph, Mikey and Donnie and they introduced you to Leonardo who quickly fell in love with you You were a yokai girl who was actually a mutant turtle like them but only you camouflaged yourself with a small bracelet, let's say you didn't like Leonardo at all because of his pride but he always flirted with you. Leonardo was serious when he wanted to be and argued a lot with Raph
