Glitter

Glitter.

It shines, it sparkles, it's multicolored, and oh Gods, it just came from that exploded Sue!

Glitter is a common substance to be found in the average Mary Sue. It's what makes them so sparkly.

It is found in their blood, and if you decide to perhaps sample a Sue Soufflé in the Cafeteria, it will also be found in your stomach.

Some Agents are allergic to glitter.
