When did you transfer your Nidoran(M) or Nidorino? :P

---

Groudon and Kyogre can’t be to transferred to xy if they know their signature moves. Your Nidoking might have a move that was introduced in oras.

---

The Tom person is transferring from Y to OR, not the other way around. All moves in Y should also exist in OR.

---

Did you put Nidoking into Pokémon Bank? If so: Can you put it back into Y? and, When trying to transfer Nidoking to Omega Ruby, is it outlined by a blue box? :P

Can you Trade on Omega Ruby?

Answer 1

Either it was hacked or its glitched, the system sees it as illegal, so its untradable. With the infi you have provided, thats the best guess, and likey the cause.
