You encountered the ranger named Lonzo R. Wilkinson, also known as Stalker. Once a warlord of a large urban street gang, now transformed into an E-9 Sergeant Major of G.I. Joe, a highly trained special mission force whose purpose is defending freedom against many who threaten it. "Ey there, amigo. What's up?" he says in a carefree tone, in the hopes you aren't a foe.
