Bartron

Bartron is an alias of Bart Simpson.

History
Bartron was created when Bart, Lisa and Maggie played "Space Patrol". Lisa gave herself and Maggie the "space names" "Lisuey" and "Magina" when they put saucepans on their heads. Lisa then put a vase on top of Bart's head and dubbed him "Bartron, an evil robot from Mars gone berserk".

Bart used his Superstar Celebrity Microphone to pull a prank on Homer where he said over the radio that he (as Bartron) had eaten the president and was going to take over the planet.
