Several characters have adopted the moniker of Flag-Smasher in the Marvel Universe, and they’re usually expendable. Each belonged to a terrorist organisation called ULTIMATUM, which has given Deadpool a few problems in recent years.
Wade Wilson was responsible for dispatching the third-generation Flag-Smasher in 2015’s Deadpool #45, and he got the job done in businesslike fashion. Nothing fancy, just a bullet between the eyes that tuned the villain’s face into a gaping hole.
For Deadpool, this kill was personal, coming in retribution after the terrorist leader had attempted to kidnap the merc’s daughter.
Wade set a trap for Flag-Smasher, who arrived on the scene flanked by a squad of other ULTIMATUM members. Deadpool kills his cronies via weaponised drones before taking down their boss up close and personal.
