|First appearance||Bender's Big Score|
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 Doomproof platinum vest.
- In "Rebirth", the doomsday device used to power Bender looks exactly like the Spheroboom, although it is possible that the professor had built another one.
