Question

what would I get if I breed a lucario and jolteon?

Answer 1

It Depends on the Gender, If Jolteon is a Girl and Lucario is a Boy, then you will get a baby Eevee. Likewise, If Jolteon is a Boy and Lucario is a Girl, then you will get a baby Riolu. See their evolution chains and the breeding page for more details.
