Lord Krarn was the leader of the Warmongers who invaded Earth in a television programme. Even though he was fictional, he could lead a life of his own within the dimensional bubble where the TV programme took place. His wife was killed by Jack Laser. He killed Flip Jackson, which caused the security protocols to shut down. When the security protocols were down he left the programme. He then tried to take over the galaxy to wipe out all forms of life. (AUDIO: The Fourth Wall)
