It's been a good couple of years for Deathstroke fans as the iconic supervillain showed up briefly in Justice League, as played by Joe Manganiello, and has also put in appearances on several seasons of Arrow, with Manu Bennett's portrayal widely considered to be the best Arrowverse big bad to date. And then there's also Will Arnett's more comedic version in Teen Titans Go! To The Movies, which was very enjoyable, too.
