MATT the Dark MATTer!! 

It is the Astroparticle Physics Lab's mascot and the stuff of dreams (Or nightmares, depending on whether you are pro or anti-Dark Matter existence). 

True to nature, Matt prefers to be hidden, except for when it doesn't. Depending on its mood (and the sensitivity of your detector) it might allow itself to be detected (or that is what we hope).

Things Matt can do:

• Blink.

• Avoid detection. In fact, it passed Batman-graded camouflage tests.

• Construct a website (wears helmet when doing so).

• Get dressed for events that don't exist.

• Transform between the different categories of Dark Matter like a magical girl (Wand and transformation dance are required. Bippity boppity will not do).

• ...Oh, It can read too!
