On Halloween, the Howling Commandos have been enlisted by Nick Fury to hunt down the Agents of S.M.A.S.H. while they were trick-or-treating in Salem, Massachusetts. The Howling Commandos end up helping the Agents of S.M.A.S.H. fight Dormammu and the Mindless Ones at the time when Dormammu was targeting a magical hourglass with the powers of order and chaos that is held at the Salem Museum.
Hulk pursues The Leader to 1890 during the Victorian era where he manages to put together the Howling Commandos with Frankenstein's Monster, N'Kantu the Living Mummy, and Werewolf by Night's grandfather to thwart Dracula and Leader's plans to blanket the Earth in darkness with their Gamma Furnace.

Powers and Abilities
Jack Russell is a descendent of the mystically altered offshoot of humans known as Lycanthropes. During the night of the full moon and the two nights surrounding it he is forced to transform into a werewolf, a large, powerful form which is a hybrid of human and wolf, and loses his human intellect. Through a series of events, he is also capable of transforming voluntarily outside of the full moon, at which time he remains in control of himselff. In this form, he possesses superhuman strength, speed, stamina, durability, agility, and reflexes. He possesses a superhuman sense of smell, which carries over to his human form. He has razor sharp teeth and claws able to rend light metals. The werewolf is resistant to many forms of conventional injury and very hard to kill by conventional means. Though he can be severely wounded, he recovers from non-fatal wounds much faster than a human would. He is vulnerable to magical attacks and, like all supernatural creatures, he can be killed by weapons made of silver, due to its inherent mystical "purity".
