There should be a lady gorilla, like Donkey Kong in drag. A quirky inventor ape lady who's inventions are always blowing up in her face.
She could be like Amy Rose to Winston's Sonic, right? Like, she could be all like "Winston Senpai" and he would be all "eugh, get away from me. You're such a dummy and weird." but then she would use her superior intellect to build a banana gun and her up smash could be like Wario's fart except a poop canon or something. Then Winston would be like "sorry bb, I misjudged you" but then she'd be like "You made me realize that I'm into omnics". Do omnics have genders? I don't think they should. Her and Winston would always have this awkward tension thing going on during that safe room banter. She could have all sorts of saucy lines like "Don't make me go banana's on you", "Did you just call me a monkey?" or "And they said my invention would never work, HMPH!"
Yeah, that'd be sick.
