NATO agent. Major Klaus Heinz von dem Eberbach's second in command. Married. Mostly seen with Agent B. In Alaskan Front, he dives for the treasure in Tazlina Lake. In Iron Klaus, Agent A has curly hair. In later issues his look changes to short, straight hair. Possibly the first Agent A was replaced by a new Agent A (possibly the previous Agent B). In Hallelujah Express, Dorian takes A's wallet, for "safekeeping". (Source: Wikipedia)
