Name all the Pokémon rivalry that you can think of. Can be predator-prey relationships but preferably both on equal grounds. Like Durant is the prey of Heatmor but the Pokédex says that they can defend themselves. Since the new Pokédex entries I need to see the ones I'm forgetting.
I'll start.
Zangoose vs. Seviper
Kyogre vs. Groudon
Heatmor vs. Durant
Meowth vs. Murkrow
Sableye vs. Gabite

I can't think of anymore.
