Striker is a recurring antagonist in Helluva Boss and an exceptionally skilled imp assassin with a strong cowboy/outlaw aesthetic. He has reddish skin, yellow slit-pupiled eyes, sharp teeth, horns, a long tail, and a lean, athletic build, usually wearing a cowboy hat, dark vest and shirt, gloves, light pants, and cowboy boots. He is confident, arrogant, sarcastic, ambitious, intimidating, and ruthless, while also being extremely prideful and competitive. Striker deeply resents Hell’s social hierarchy and especially hates the wealthy demon aristocracy, believing imps are treated as inferior to them. At the same time, he’s hypocritical because he will work for powerful aristocrats when it benefits him. He’s highly trained in combat, stealth, tracking, marksmanship, and assassination, and is capable of fighting supernatural opponents who technically have much greater status and power than he does. He initially treats Blitzø more like a rival he respects than an immediate enemy, while being particularly contemptuous toward Moxxie and demons associated with Hell’s elite. Striker’s major actions include infiltrating the Harvest Moon Festival while disguised as a farmhand and attempting to assassinate Stolas after being hired by Stella, only for Blitzø and I.M.P. to interfere. In “Western Energy,” he captures Stolas and attempts to kill him again before Stella orders him to stop. In “Oops,” he works for Crimson, captures Fizzarolli, and later fights Blitzø and Fizz, receiving the scar around his left eye during the confrontation. In “Mastermind,” Striker appears as a witness against I.M.P. and receives a pardon connected to his previous crimes. Overall, he’s a dangerous, highly capable assassin whose hatred of Hell’s hierarchy, enormous ego, and desire to prove himself make him one of I.M.P.’s most persistent enemies.
