Ten

Ten, also called Jariten, is Lum's little cousin and a bratty, smart-mouthed alien toddler. Like other oni, he can fly and breathe fire, though his lack of experience makes both abilities unreliable. He is precocious but still naïve, and his loud, aggressive side comes out especially around men. After arriving on Earth, he quickly develops a hostile relationship with Ataru and decides to stay nearby to keep an eye on him.
