Fictional character biography
He was introduced in New Teen Titans #2 (Dec 1980) as the butler of Deathstroke the Terminator. In later issues, and Deathstroke's own title, it was revealed that Wintergreen was a former member of the SAS who rescued Sgt Slade Wilson (the future Deathstroke) from a bomb, who in turn would rescue him from a Viet Cong prison.
Although Wintergreen did not have Deathstroke's abilities, he had more experience and often acted as his mentor. Since Deathstroke was devised as the criminal version of Batman, Wintergreen was his counterpart to Alfred.
When Deathstroke (temporarily) retired, Wintergreen honoured him by running Vigilance Inc., a search-and-rescue operation originally set up as a mercenary organization by Slade's ex-wife, Adeline. He was subsequently killed (and has his head mounted on a wall) when Jericho took over Slade's body and attacked him. Although Jericho was in control of Slade, Wintergreen apparently had believed he would be murdered by Slade eventually, evidenced by his apparent last words of "I suppose it was only a matter of time."
In other media
- Wintergreen makes occasional appearances in Teen Titans. Unlike Slade, Wintergreen is never referred to by name. He is first seen in the episode "Divide and Conquer" when Cinderblock delivers Plasmus to Slade. He is almost never seen out of his master's lair except in "The Lost Episode" (which never aired on TV but was a promotional episode for Post Cereals) where he is part of the crowd running from Punk Rocket's Rock N' Roll rage. He later appeared as a member of the Brotherhood of Evil, participated in the final battle against the Titans, and was frozen along with the most of the Brotherhood, once they were defeated.
- Bill Wintergreen appears in the CW TV show Arrow, portrayed by stuntman Jeffrey C. Robinson. Wintergreen is a close friend of Slade Wilson, and the godfather of his son, Joe, and like Slade is Australian (and is mentioned to be an ASIS Agent and former member of Team-7). In this version, Wintergreen is as evenly skilled in swordsmanship, armed and unarmed combat and peak athleticism as Slade is. Wintergreen is the show's first incarnation of Deathstroke. In the fifth episode, "Damaged", Wintergreen is part of mercenary unit led by Edward Fyers to locate Yao Fei on the island, Lian-Yu. He is sent by Fyers to torture Oliver Queen over Yao-Fei's location at Fyer's tent, until Yao Fei launches a surprise attack and subdues Wintergreen. In "Year's End", Wintergreen rescues Fyers from Yao Fei's capture and bests the latter in combat. He is explained to be Slade's former partner. It was revealed that both Slade and Bill were members of the ASIS who arrived on the island to rescue Yao Fei. After their plane is shot down by Fyers, Wintergreen defects to Fyers' side while Slade refused. In the fourteenth episode "The Odyssey", Wintergreen is stabbed in the eye by Slade, and seemingly killed.
In Batman: Arkham Origins, Batman's profile on Deathstroke says that William Randolph Wintergreen is an associate of Slade.
