Charles Chandler (Mega-Earth)

History
Chuck Chandler was a NASA test pilot in the late 50s who, during a test flight on an experimental rocket, the XF-13, got caught by a Skrull spaceship. The Skrulls tried to make him reveal some information about NASA's space program.

Chuck managed to escape but he destroyed the Skrull's spaceship's energy core in the process. He absorbed the radiations emanated and, when he landed in the desert, where his brother Hal was waiting, he disappeared as a red and green image on Hal's lenses.

Then Hal discovered that he could bring back Chuck just by focusing on his brother's image inside his glasses. When Chuck comes back, he gains the strength, speed, and stamina of three men. Chuck can remain in the three-dimensional world for just 3 hours and, after that time, he must return inside Hal's glasses. Thus, 3-D Man was born!
