Harley Keener (Earth-SD01)

Harley Keener was a normal kid from Minnesota until he came across Vic Stark in his garage. He later helped Vic find out the truth about AIM's illegal activities, as well as keep an eye on the Mark 42. As a reward for his help Tony gave Harley a large variety of new tech to use in the years to come.

Eventually, he works with Vic on creating his own armor, becoming the Iron Lad.
