Stephen Hawking's head

Stephen William Hawking is a theoretical physicist and a member of the Vice Presidential Action Rangers. Like Al Gore's head, in the future his jar is rocket powered. He still can't speak so his jar acts as a robot with the same speaking voice. He has the ability to shoot lasers from his eyes which can temporarily stun people, though he never knew he could do that until he actually did it. In a non-canon segment, he ultimately quit physics and became a voice-over actor for cartoons.

Personality
In the show, Hawking appears extremely lazy and mean, often stealing credit for other people's discoveries, frequently naming them after himself - for example the Fry-hole, which he called the "Hawking hole" in spite of Fry being the discoverer. When asked if he was the one who created, he gladly played along. Hawking misuses his power and name in academic circles, assuming that no-one will believe Fry over him (which is probably quite true).

Biography
In a What-If scenario of the year 1999, Hawking is shown to be a regular at Panucci's Pizza, and he often steals credit for other people's discoveries, frequently naming them after himself. He, Fry and the rest VPAR were sucked into the Fry-hole at the end of the scenario.

In the 31 century, Hawking is still a well-known and respected physicist, and he is among the scientists trying to understand the anomaly. However, in spite of having written a book on the subject, he still doesn't understand it.

Production
Even though in real life, Hawking is completely paralyzed, in animated form, his eyes blink and he makes some proper facial reactions. This mistake was made on his appearances on The Simpsons as well, though in his appearance in The Beast with a Billion Backs he appears to be completely paralyzed.
