Your rival is kind and supportive, and you’ll meet him often during your quest. In fact, he begins his quest shortly after you pick your Pokémon. He’s from Aspertia City, just like you.

His Pokémon depends on which starter you choose:

If you chose Suicune:

Raikou	Mareep	Pidgeotto	Sandshrew	Tauros	Lapras

If you chose Raikou:

Entei	Mareep	Pidgeotto	Psyduck	Miltank	Onix

If you chose Entei:

Suicune	Mareep	Pidgeotto	Growlithe	Lickitung	Larvitar

N.B. They will sure evolve over time, and the last time you will maybe meet him is at the Pokémon League on Mondays and Wednesdays, and all of his Pokémon are around Lv99, so be prepared for a tough battle!
