This article is about someone who is an enemy to the Pookie Hater Defense.
Agent Xetrov was featured in Operation Infiltration II, he along with Agent Oob and other negative counterparts were accidently transported to the Positive Dimension by Agent Boo's Time Machine. They eventually decide to go and look for Onega X but they ended up running into their positive counterparts.
The negative counterparts trap their positive equivalents into a cage. They eat Chip Chip Hurray and Agent Vortex mocks the negative counterparts. Agent Oob gets angry and calls in Robot Oob -3, while Agent Xetrov calls in Tuo-Kcalb to help Robot Oob -3 destroy the positive equivalents.
Later in the mission, Agent Oob and Agent Xetrov, along with other negative counterparts, team up with Agent Batman and eventually find their Positive Counterparts. Agent Nightmare saves the positive counterparts in his Nightmare ship and attacks the DHP agents. However Agent Oob and Agent Xetrov get angry and decide to call in Robot Oob -3, Nortluv and Tuo-Kcalb, but Agent Boo and Agent Vortex call in Robot Boo 3, Vultron, and Black-Out and the robots attack eachother causing massive destruction.
Suddenly an earthquake starts to rumble and everyone sees that the Omega Tower is slowly tipping over. Agent Oob and Agent Xetrov try to tell their robots to escape. Agent Oob and Agent Xetrov and all of the negative couterparts return back to the Negative Dimension when the Omega Tower was about to be destroyed.
