How to Piss off Shadow
Begin singing "I am all of me" every time he walks by.
Scream "FIND THE COMPUTER ROOM!"
Tell him he should curl his chest fur.
Let the mad fan girls loose.
Steal his emerald and hide it in the X-Tornado.
Get Cream to go up to him and ask, "Mr. Shadow, why are you emo?"
Tell him that his true purpose is to be a female.
Accuse him of being a re-color.
Ask why he needs a motorcycle when he has rocket shoes.
Tell him that Lord Voldemort is more badass.
Same goes for Nazo.
Have Charmy follow him around while singing the goofy goober song.
Finally, when he is thoroughly pissed off, ask him if it's his time of the month.
Run for your life.
