Zoovac 2.0 is an upgraded form of Zoovac. Zoovac may take this form sometimes, as the programming for it is now embedded under his own programming. He has been seen to transform involuntarily when threatened.
The Zoovac 2.0 persona is deeply evil. It was taken from an alternate universe's version of Zoovac, and implanted within our own Zoovac's personality as a backup. Once the Zoovac 2.0 program activates, it causes him to transform into a physically threatening and dangerous robot.
