Morg is the main antagonist of the Phineas and Ferb episode Mind Share. He is an alien criminal who plots to get out from prison and loot in another planet.
He was voiced by Carlos Alazraqui.
He first appears on Phineas and Ferb's galactic inter-web, advertising what seems to be a vacation deal. The boys, along with Isabella, Buford, and Baljeet, agree to the deal and build a machine which they use to swap minds with Morg and his cellmates. It is then they find out this was all a trick and that they have been trapped in prison, as Morg and his inmates plan to free themselves so that they can loot anything on Earth. Eventually, Candace finds out about the plan and sets off to stop Morg. As the kids get to work on another device to send them back to Earth, Candace lures Morg and his teammates back by using hypnotic square-dance music to lead them back into the mind-swapping machine and finally returns them all to normal, sending the kids back to their original forms and Morg and his inmates back in prison. Upon being caught red-handed by the head guard, Morg replies to the guard that he's been framed, but the guard isn't fooled. It is implied that Morg and his inmates will receive a severe punishment for attempting to break out.
