Not necessarily a super-villain, but as a thief, you could break open windows to get in and out of buildings, and repair them afterwards to cover your tracks.
If you want to actually hurt people, you could carry a bunch of window panes around, slip them around peoples' bodies, and repair them, presumably cutting off any body parts that intersect the glass.
For supervillainy, you could fit these around entire buildings to destabilize them, or hold important people hostage, tied up with a windowpane around them.
If we're talking the OS (which you said you're not but may as well) then you can probably make a killing in IT.
Power: When you're waiting for something to happen, time fast-forwards for you until it happens. It doesn't fast-forward for anyone else, though.
EDIT: Goddamned ninjas.
Gimme a sec to do a power for the previous poster...
Ok.
As either a hero or a villain, emit a cloud of the scent strong enough to send whoever smells it into coughing fits, unable to do anything.
As a villain, this allows you to do as you please.
As a hero, this allows you to take down evildoers nonlethally.
EDIT2: As stated, my power submission is "When you're waiting for something to happen, time fast-forwards for you until it happens. It doesn't fast-forward for anyone else, though."
