Tsar bomba
That's it alright.

Without the ASPLOSION. Doesn't match huh?
The Tsar Bomb, also called Tsar Bomba by Russians, is currently the largest nuclear bomb on the Unearth. It is a quarter of the Chuck Norris Roundhouse Kick, and is what you get when you x10 TIMES ASPLODE. A Wa- version could be very dangerous... but it's a good thing it isn't Wa-fied! Not only is the tsar bomb dangerous, but it has radiation. So even if you survive the explosion you will die of a disease. The only way to not die from the disease is to wear a very powerful Gas Mask and even that might not work. So in conclusion, a Tsar Bomb is not a toy. I'M TALKIN' ABOUT YOU KID!!!!
