My rather childish sense of fun thought "why not?", and so ...
If I were a superhero:

I would be ... ADMIN GIRL! *cue triumphant fanfare*
(This is what I'd look like) -------------------->
Admin Girl *cue triumphant fanfare* is a pirate princess (hence the tiara and eye patch); ab
ducted as a small child from her fabulously wealthy father's private yacht by the notorious evil pirate, Long John Travolta and raised as his daughter, she is deadly with a sword, proficient at tying knots, swears like a trooper and can dance the hornpipe.At the age of 21 she ran away, tired of the pillaging, and parrot crap, and went to the big city to seek her fortune. Only to be disappointed and disillusioned on finding herself stuck in a dead-end office job.
Her dreary life was to be transformed though following an incident involving some radioactive Tipp-Ex and she awoke the next morning as ADMIN GIRL! *cue triumphant fanfare* Her mission, to seek out the best admin jobs, take two hour lunch breaks without getting caught, reach the top of her salary scale and rid the world of evil, bottom-dwelling bosses.
Her superpowers include being able to type at the speed of light; figuring out how to use mail merge; fax documents using only her mind; do sums in her head; spot a randy businessman from 50 paces; sharpen pencils using her thighs
Her weapons of choice are a staple gun and a bottle opener.
Her arch-enemies are:

BossMan. Master of corruption and bullying tactics with inappropriate delusions of grandeur, halitosis and a comb-over Donald Trump would be proud of. Threatened by strong, intelligent women he is obsessed and consumed by his desire to destroy Admin Girl *cue triumphant fanfare*
SuperAmbitious&SluttySleepMyWayToTheTopGirl.
Scheming, two-faced bitch, she'll stop at nothing to get that pay rise or promotion first.

Admin Girl's *cue triumphant fanfare* catchphrases are:
"It's spreadsheet time!"
"Oh my stockings and garters!"
"Bite me IT geek"
"Your bullet points cannot harm me! My Norton is like a shield of steel!"
"My wine bar senses are tingling"
"Suffering secretaries!"
"Holy hole punches!"
So which superhero would you be? If you fancy creating your own then have a look at the Hero Machine site, to get you started. It's kinda fun if you don't have anything better to do.
And here's some superhero themed music for inspiration ...
Sometimes I think I spoil you.
