Thubanian leader

The Thubanian leader is the leader of the cats from Thuban 9. He uses a puppet, Professor Morris Katz, to interact with the human upper class. This took the role of Leela's pet, Nibbler, for a few days during the Thubanian invasion. His collar started to glow when his race was near to stealing the Earthican magnetic field, as did his companions'.

After Amy presented her thesis in Mars University, the Thubanian leader followed her to Planet Express, and then his friends followed him as well. He began infecting Leela with cutie pie demonstrations, and soon every member of the company was under the controle of those darn cats.

The Thubanians convinced the crew to build something sinister, actually the machine from Amy's thesis. After "sending" the electric current generated by the machine to Thuban 9, they left Earth. However, as the employees managed to "bring it back", their planet was probably destroyed. The leader may have been able to save himself by fleeing, though.
