Raymond Phelps worked as a maintence man at a hotel where he met Dr. Mannish Nadir. Phelps was on the short list to be fired due to his laziness and general stupidity. Nadir found him to be the perfect pasty and had him be his gofer and general whipping boy.
When told he was going to be given meta human powers, Phelps said, "Cool, can I get a big honking ray gun" Nadir rolled his eyes and said, "Yes, but if you can't handle it, I will take it away from you." He gave him a plastic toy Space Ranger gun.
When he underwent the spell, even Nadir didn't understand the nature of his powers. At first, he called himself Ray Gun, due to the plastic gun's new found powers of well, shooting various rays.
Then he was defeated, fell into the ocean and transformed into the slightly scary Manta Ray. Then he was defeated.
In prison, he escaped by shrinking out of his cell. Now calling himself the very imaginative Shrinking Ray, he plotted his come back, only to be defeated again.
He then became Freeze Ray, but was put back on ice.
Then he transformed to X Ray, and was unsolid and radioactive. He was beaten so bad, he was killed.
But death couldn't stop Death Ray. Or could it? Yes, kind of. I mean, he came back from the dead but got his ass kicked again.
Now being moved to his own holding cell in the Aortic, for safety reasons, Raymond Phelps got a bit angry. So angry he swelled and became ultra strong, and slightly radioactive. He called himself Gamma Ray. He was so strong that he had to be tossed into the sun.
And that is the end of poor slub, Raymond Phelps.
Or is it...?
