Killjoy possesses no superhuman powers and relies on a wide variety of weapons that he has shown to have great skill at using. He has also demonstrated the use of military tactics and assassination skills.
Weapons: Killjoy carries a large arsenal of weapons that are housed mostly on his back. He has two Adamantium blades that snap together to make a large double-bladed sword which he can use to deadly effect, plus an assortment of other small-bladed knives in his boots. He has a wrist mounted weapon that fires a blast of metal shrapnel, an assortment of guns that shoot an unidentified form of energy and a flame thrower with a limited range and fuel capacity.
Killjoy was a mercenary working for Moses Magnum in Canaan. Killjoy believed in Magnum's vision of turning Canaan into a free nation of Africa that African-Americans could call home and escape the prejudice they suffered in the United States. Although uncomfortable with some of Magnum's actions, Killjoy was willing to kill and compromise his ethics in order to achieve those goals.
Killjoy attempted to assassinate the Black Panther, ruler of Canaan's neighbor Wakanda, as part of Magnum's schemes to overthrow the nation for the greater good of Canaan.
