Rick sought to avenge his brother Dick, who was killed during his crusade against mutantkind (sort of). From within his absolutely impenetrable laboratory, Rick Chalker had his robot amputate both his hands and replace them with large propellers.
Delighted with his transformation, Rick proclaimed himself the Number One Fan and destroyed his robot servant, since the operation was completed and he was now all powerful. However, without hands, he could not reach the recessed release button to get out of his absolutely impenetrable laboratory. Shocked at his own stupidity, Rick angrily slapped his own forehead...and the razor-sharp propellers killed him.
Chalker's spirit was sent to Satannish's realm of Hell.
Satannish (as Nick Cloot) resurrected Number One Fan—alongside Carnivore and Professor Vic Chalker, as X-Factor's greatest enemies, sending him to join Charon in his attack on X-Factor. Rick took on Quicksilver, but found the mutant too fast for him to hit even once. Rick then threatened to behead the stunned Wolfsbane, but Quicksilver quickly rescued her and punched Rick aside. When Polaris blasted Vic Chalker through the air, Number One Fan tried to catch him, but neglected to consider the propellers on his hands and chopped up Vic pretty badly. Enraged, Vic used a laser to cut Number One Fan in half. Shortly thereafter, Satannish/Cloot took Charon as his own prisoner, and the Chalkers three were never seen nor heard from again
Powers / Abilities
Number One Fan had large propellers in place of each hand with which he could slice through most forms of matter. However, he lacked actual hands to perform normal tasks. In addition, he rarely considered the consequences of his moving propellers. He did not appear to use the propellers to fly. He was intelligent enough to design a robot capable of performing complicated cybernetic surgery.
