In Black/White, Morimoto will only battle you after you enter the Hall of Fame. He has a Liepard (v.75), Simipour (v.75), Simisear (v.75), Simisage (v.75), Swoobat (v.75), and Zebstrika (v.77). His team is something that feels genuine, if unremarkable and underwhelming.
In Black/White 2, he has the same team, but they're all Level 76 up to Zebstrika, who's Level 78. Also available is Nishino, who uses a Clefable (v.76), Azumarill (v.76), Lickilicky (v.76), Wigglytuff (v.76), Alomomola (v.76), and Snorlax (v.78). Same deal as with Morimoto; it's nothing terribly out of place, like a full team of pseudo-legends, shiny Pokemon, legendaries, "high end competitive teams," Pokemon with altered base stats, or Pokemon you can't obtain that have a BST in excess of 900.
