El Matadora doesn't possess cat ears; instead, he grew ox horns on his head, which usually poses an unintentional threat to people around him, despite his protests. He works in a local meat restaurant in 17th-century Spain, though he also takes another job as a super hero with a secret identity. He is the strongest member amongst the Doraemons by raw strength. If he doesn't sleep, he can't exert his strength. He has a habit of calling women "señoritas" and immediately flirting with them.
