Personality
Ian Hawke was always quite an arrogant and unpleasant individual, however he was also not quite bad enough to be considered a true villain - this changed when Alvin and The Chipmunks started to become popular and his greed began to shine through, quickly revealing him for the control freak he truly was.

Ian was a bully, a shameless glory-hound and above all else a man who would go to any lengths to get what he desired - caring very little for anyone else (he is also, arguably, a parody of the music industry itself - treating his "stars" badly and using them to boost his own career).

By the sequel Ian's personality had darkened considerably and while he still managed to convince the Chipettes he was a "good" guy he was much quicker to reveal his true colors - being obsessed with regaining power and being openly abusive towards the girls, at the end of the sequel it is hinted that Ian has gone slightly insane as he desperately tries to cling to fame even when being booed off the stage by his once adoring public.

Powers
Ian Hawke did not possess any superhuman or mystical powers, being an ordinary human - however he was once a rather successful and rich business man with great power, which he lost due to his own bullying nature: by the sequel Ian had been reduced to a pathetic excuse for a human being so devoid of power he was literally forced to wrestle with rats for food, though he was still good at manipulation (though he was considerably more skilled at it in the first movie, his bitterness in the sequel making him a much more obvious villain). By the third film, Ian is a secondary antagonist next to Zoe. Although his personality has not changed, he in the end somewhat restores his friendship with Dave and the Chipmunks.
