Joust Rod

Number Nine has a rod that extends to be very long and can be used to kill Mogadorians and Mogadorian beasts.

In I Am Number Four: The Lost Files: Nine's Legacy, his Cêpan Sandor mentions that there used to be competitions on Lorien with these red rods, called jousts.

This rod is Nine's primary weapon. However, it was broken by Five during the fight in The Fall of Five.
