I dont think you can

if you beat him but didnt catch the zangoos then just waite until miror B guy gets it...and remember every shadow pokemon you end up fainting, miror b will end up having them. not in the exact order you beat them in ,.. but he will have them.

if you find his zangoose at gateon port
if you want to catch it go to the key lair and capture it teh second time after you find your capture machine

You can battle zook when you get your snag machine back from team snagem.
