ALVIN. The stepson of G.I. Joe team member Lonzo "Stalker" Wilkinson, and son of his wife, Lydia. After Stalker's family moved into housing at Wright-Patterson Air Force Base (home of the reinstated G.I. Joe team's first headquarters), some tension began between Stalker and Alvin. When Alvin snuck out one night and starting hanging around with a street gang, Stalker tracked the teen down and found Alvin was in danger. After Stalker saved him, his stepson was impressed and he and Stalker's relationship began to improve. (FL 15; AE 20)
