Originally seen alongside the Thunderbolts army during the superhuman Civil War, this Death Adder has also been seen alongside a new incarnation of the Serpent Society.
Death Adder started working for the Assassins Guild, and took part in an ambush with some of the Guild's top mercenaries when Deadpool raided the Guildhouse as part of an ongoing feud between him and the Guild. Before engaging the Guild's assassins, Deadpool threw a shuriken at Death Adder without looking and hit him in the head, killing him. Deadpool lamented the shot, claiming that he was aiming for Lord Deathstrike.
The character was created to replace the original Death Adder, Roland Burroughs, who had been killed by the Scourge of the Underworld, and to fill in the ranks of a revived Serpent Society. Burroughs was eventually resurrected by the Hood and remains a more prominent character than his would-be replacement.
