I wish Colress had appeared in 4th Gen as the frontier brain for battle factory. He has the looks and personality for it to be a natural inclusion. The whole point of Battle Factory was to test the trainer's knowledge of pokemon battling. Colress, being a scientist, naturally seeks to gain more knowledge about pokemon, right? And he can use his touchpad to gauge the strength of his opponent's pokemon. He looks better than Thorton, at any rate.
