Wendell Vaughn as Marvel Boy (Earth-616)

Wendell Vaughn was born in Fond du Lac, Wisconsin but raised in Oshkosh. He had served in the US Army with distinction, eventually being promoted to Lieutenant. After the army, he applied to join the S.H.I.E.L.D. Academy. He graduated with full honors, but his records stated that he lacked the so-called "killer instinct" needed to be a field agent.

Assigned to routine guard duty at the Stark International project studying the "Quantum Bands", he watched as the Bands were field-tested by William Wesley, S.H.I.E.L.D.'s top tech-jockey, who panicked when the Bands would not come off and disintegrated himself. Not an hour later, androids sent by the criminal organization A.I.M. staged a raid. Their objective: to steal the alien energy-bands. To protect them, Vaughn put them on -- and learned the fundamentals of their operation under the most hazardous possible conditions. Still, he managed to repulse the AIM invasion. And ultimately, it was his lack of a killer instinct that enabled him to subdue the rampant energies he had unleashed.
