Shiv Katall

One of the most feared mercenaries in the universe, Shiv Katall was frequently hired by Zurg to hunt down his rogue minions. In actuality, Shiv Katall was an identity assumed first by Commander Nebula, and later by Buzz Lightyear, to help defectors from Planet Z seem dead so that they can go into hiding. Buzz's masquerade was briefly exposed, but the identity was preserved thanks to Commander Nebula. The identity was also briefly claimed by Buzz's evil alternate counterpart to commit thefts.
