Adder is a character who has appeared in Advance Wars 2: Black Hole Rising and Advance Wars: Dual Strike for the Game Boy Advance and Nintendo DS respectively. He considers himself to be one of the best officers, and thus conclusively decides that he's unbeatable, though this thought is ultimately brought to an end when he is defeated at Yellow Comet. He is not included in the plot of Advance Wars: Dual Strike, but can be bought after completing the game.
