Who's your favorite Marvel hero? Well, you won't have to choose between one or the other anymore with these heat-sensitive mugs by ThinkGeek. At first glance, the mugs look plain, with the word 'Hero' printed on it in black. But fill it up with steaming hot coffee or cocoa and your favorite heroes will come to life in screaming color.
You can also opt for the 'Evil' mug if you're rooting for them instead of the Avengers.
