When Slade Wilson was 17 years old, he enlisted in the United States Armed Forces, and went on to be an exceptional soldier, earning decorations for valor in combat. During this time, he married fellow soldier Adeline Kane, who bore him a son, Grant, who they raised together. Eventually, Slade, along with fellow soldier Alexander Fairchild took some mercenary work, which they likened to babysitting arms dealers. Some time after that, they were both part of a covert ops team known as Team 7. During a mission where the team had to secure a plan known as “The Majestic Project”, the team suffered a terrible tragedy, ultimately resulting in the team going their separate ways. Over the course of the team’s short-lived tenure, Slade unknowingly endured experimentation. Slade discovered he could heal faster than other humans. Some time later, Slade volunteered for an experimental procedure, which unexpectedly woke Slade into a rage, attacking the guards and scientists, before he was subdued. As the treatment was unstable, Slade suffered from Hyperadrenalism, a condition where he spent time passing in and out of consciousness. He was watched over by two of his former associates. Although Adeline and Grant visited him, he fell into a coma, eventually waking up to find that the experiment he volunteered for was scrapped, with Slade himself receiving a full pension. After his recovery, he began his work as a super-powered mercenary.

For this character, you will need to refer to Ron Pearlman's performance from Teen Titans for the Primeverse version of the character, who will most likely have only two or three lines at the beginning of Chapter 1. The Injustice Deathstroke, however, will need to be similar to the performance from Arkham Origins, provided by Mark Rolston. You are welcome to combine both, but if you choose to do so, make the Injustice version of the character sound grittier and more no-nonsense.
