You can't catch Level 100 Pokemon in any Pokemon game. The highest catching Level in Pokemon is Level 80. You need to raise your Pokemon to Level 100 or trade for a Level 100 Pokemon to get one. You can also challenge Level 100 Pokemon, but only in the organized challenges of the Pokemon games (i.e. Battle Tower, Trainer Tower).
