This Pokémon evolves as a result of a low friendship level with its trainer while also knowing the move Frustration. Omeneon's evolution is the result of an Eevee being subjected to emotional and mental anguish, causing a chemical imbalance in its brain, which causes it evolve near a graveyard, temple or any other place of rest. Omeneon never appears during the day, it only appears at night to feed on the energy of Pokémon by wrapping its bandages around them and sucking them dry, thus absorbing their life force. Its bandages are strong enough to crush a car and restrain a rampaging Tauros. It seems to have a rivalry with the Pokémon Houndstone, and attempts to steal the headstone-like mass protruding from its head for mysterious reasons which remain unknown.
