On the Friday Night on Planet Ripper, Zaydon appears next to Ghost as he was asleep. 

Zaydon:  I'm sorry, bro. I must prevent you from doing something stupid.

    Zaydon slowly unsheathes the sword that was given by Future Ghost and looks down on him. The cold green eyes of Zaydon became dull and was stabs him in the heart........and the kidney.

Zaydon:  *picks up Orev and Shiva as they're asleep and begins to disappears with them*
