Worst "VS" Arguments You've Heard?

[hamishspence]

Wiping out life on a planet is a property of a few weapons in Star Wars- bioweapons, the torpedo used by the Sorcerers of Tund, the firestorm kicked off by Exar Kun's spell used to preserve himself, etc.

EDIT: the firestorm is blamed the Jedi's attempt to stop him, on Wookiepedia.

though Nihilus does rank pretty high.
