|—Thermos, "Alternate Reality Show"|
Thermos is a male contestant on Inanimate Insanity Infinity in an alternate universe, who makes his debut in "Alternate Reality Show". He is voiced by Niall Burns.
Thermos is mostly seen screaming loudly. While he's usually screaming for no reason, he is occasionally provoked to scream because of fear. He is described as "totally zany" by Pepper. Being a competitor on Inanimate Insanity Infinity, Thermos is one-dimensional, especially considering he's only ever screamed.
Thermos is a silvery vacuum flask with two dark gray bands going around the circumference of his body, with one band going around near the top of his body, and one band on the very bottom. He has no cap or lid on, and a dark brown substance (presumably coffee) can be seen inside. Both when he screams and when he doesn't, his eyes are cartoonishly empty and crazed.
- Thermos is the second character to be named after a licensed property.
- The first is Poptart.
