Actually, The 'air' is a mix of chemicals not just oxygen, he could manipulate one of the other chemicals. Or he could manipulate kinetic or 'force' energy which would do pretty much the same thing. If you have trouble looking for an ability I suggest the listing wikia.

Fair enough, I was thinking of the air as a whole but yeah you can easily choose a common element from the air. 

If looking at the power listing Wiki for things to manipulate is too long then just look at a periodic table, that's what I did. :P
