Story Concept #12 redux
All purpose sidekick and comic relief Xander Harris was determined not to be hampered by public opinion this particular All Hallows Eve. He was going to parade his love for all things comic booky and not bother about what his friends might think.
The question was who should he dress as? He wanted to tweak the noses of his fellow geeks and dress as someone obscure but awesome. He chooses Alan Moore's version of Supreme.
