The Suicide Squad: Every Actor Who Also Appeared In The MCU
2. Idris Elba
Idris Elba's Robert DuBois, aka Bloodsport, is the closest thing The Suicide Squad has to a lead character.
After being arrested for firing a Kryptonite bullet at Superman, DuBois takes on the role of team leader for the Suicide Squad when Waller threatens his daughter. Though initially reluctant, DuBois proves to be a great leader, ultimately standing up for what's right and defending Corto Maltese against Starro, although it contrasted Waller's orders and endangered his life.
Elba's MCU character, Heimdall, is a far cry from Bloodsport. Heimdall acts as the guardian of the Bifrost bridge, and as an ally to Thor in all three films in the Thor trilogy as well as Avengers: Age of Ultron and Avengers: Infinity War. Unfortunately, Heimdall meets a gruesome end in Infinity War as the Weasel of that film - that is to say, the first of many characters to fall.
Marvel or DC: Though Heimdall was always a fun addition to the Thor films, he never felt as substantial as Bloodsport does in The Suicide Squad. As DuBois, Elba gets to show more of his acting chops in a leading role.
