Spheroboom

The Spheroboom is a doomsday device owned and possibly built by Professor Farnsworth, it is his sentimental favourite. When triggered, the Spheroboom seems to bend objects around it and implode them with a green explosion of doom radiation. The only known way to survive the doom blast is to be wearing a Doom Proof Platinum Vest.

Trivia

 * In "Rebirth", the doomsday device used to power Bender looks exactly like the Spheroboom, although it is possible that the professor had rebuilt one.
