looker? you must have the question wrong, there is no one named looker in either B&W of pokemon (why because i named my character looker! :D)
looker only comes when you beat the game and he gives you a Super Rod and you meet him when you find the seven sages.
sorry can't but you can find him in other games :-( sorry
well, all we know is that looker had a pokemon which was crogunk. his name may be revealed in pokemon x and y
He pops up out of no where and tells you news about N then leaves.
