Plot Summary
An excellent yet egotistical alien pilot by the name of Karp is recruited by Lotor and Haggar to pilot a new Robeast for Zarkon against Voltron.
Despite protests from Mogor that Karp is not disciplined enough for the task. Karp is given the responsibility of piloting Haggar's newest and most powerful Robeast.
When he arrives on Arus, Karp wreaks havoc. The Voltron Force do their best, but simply can't keep up with Karp and his Robeast. Upon his return to Planet Doom, request he be made Governor General of Arus after he defeats Voltron. This annoys Mogor to no end.
Meanwhile the Voltron team train to try and surpass the speed of Karp's Robeast. Soon enough Karp returns and they put their training to the test. The training pays off as the team is able to bait Karp into overtasking his Robeast. Karp is eventually defeated when his Robeast is pushed past it's limits and he is forced to flee.
Mogor makes it clear to Lotor that he is not disappointed that Karp had such a short career as Governor General. Lotor states that Karp could still be useful in the future, unfortunately Karp did not make a very good landing and would likely be in no condition to fly for some time.
