In the movie, when Amanda Waller (played by Viola Davis) introduces Blood Sport (played by Idris Elba) to Peacemaker (played by John cena) Bloodsport says “You just said each member of the team is chosen for their unique abilities, he does exactly what I do”. To which Peacemaker replies “But better”.
