Sheldon Coopers 'Destroyer' Shirt

Here's a shirt featuring Destroyer. Destroyer, from what I understand (hurting my nerd-cred here, I know), is a character (or object?) from Marvel Comics, and is regular a foe of Thor. That's what Wikipedia told me, at least. Shirt often wears different colors of this same shirt design.

Whoever the hell this robot is, you can purchase the shirt Sheldon wears from the Amazon link below.
