Agents of S.H.I.E.L.D. is an American television series created for ABC by Joss Whedon, Jed Whedon, and Maurissa Tancharoen, based on the Marvel Comics organization S.H.I.E.L.D. (Strategic Homeland Intervention, Enforcement, and Logistics Division), a fictional peacekeeping and spy agency in a world of superheroes. The series revolves around the character of Phil Coulson, with Clark Gregg reprising his role from the film series, and his team of S.H.I.E.L.D. agents, who must deal with various unusual cases and enemies, including Hydra, the Inhumans, Life Model Decoys, and alien species such as the Kree. The series was officially picked up by ABC in May 2013. The first season originally aired from September 24, 2013, to May 13, 2014, while the second season aired from September 23, 2014, to May 12, 2015. A third season premiered on September 29, 2015, concluding on May 17, 2016, and the fourth season premiered on September 20, 2016, and concluded on May 16, 2017. A fifth season of Agents of S.H.I.E.L.D. premiered on December 1, 2017 and concluded on May 18, 2018. In May 2018, the series was renewed for a sixth season, intended to premiere in May 2019. In November 2018, ahead of the sixth season’s release, the series was renewed for a seventh season.
A S.H.I.E.L.D. agent who oversees many of the division’s field operations. In April 2013, Gregg agreed to join the series after hearing Whedon’s explanation for Coulson’s resurrection, following the character’s death in The Avengers, which he called “fascinating” and “true to the world of the comics and mythology”. On whether the resurrected Coulson would be the same as before he died, Gregg said the character had to have changed in some way, but he may not understand how much he has changed. Gregg said he approached Coulson’s promotion to Director of S.H.I.E.L.D. as being his dream job, which at the same time forced the character to adopt a more level-headed attitude, like that of Nick Fury. Assuming the mantle of Ghost Rider temporarily in the season 4 finale burns through the Kree blood that healed him and leaves him slowly dying throughout season 5. In addition to a Coulson hologram in season 6, Gregg will be playing an unknown character.
A S.H.I.E.L.D. ace pilot and weapons expert, nicknamed “the Cavalry”. Joss Whedon had the character, who was originally listed with the name Agent Althea Rice on casting sheets, “rolling around in his head” for a long time. Wen was given some backstory for the character to prepare, but was not told how she gained her reputation; with May’s past revealed in “Melinda”, Wen called it “devastating.
Ward is a Hydra agent who poses as a S.H.I.E.L.D. black ops specialist. From the conception of the series it was decided that he would be a traitor, with Jed Whedon explaining that they wanted to have “infiltration based on betrayal” on a small scale to represent the same thing happening on a massive scale, and to make the Hydra reveal more personal for the characters. Following the death of his Hydra superior, John Garrett, Dalton explained that he felt that Ward was always loyal to Garrett rather than Hydra, and so without Garrett would become more of a wildcard, eventually accepting his position as an antagonist to S.H.I.E.L.D. He is killed by Coulson in season three and his body is possessed by the ancient Inhuman, Hive.
Daisy “Skye” Johnson / Quake
An Inhuman hacktivist and S.H.I.E.L.D. recruit who eventually becomes an agent with the ability to sense vibrations and create earthquakes. The character of Skye was always intended to be the MCU version of Johnson, with Tancharoen noting that the reveal would have consequences for the character’s relationships, especially with Coulson. Bennet felt that the character was someone who would wear her heart on her sleeve, but she also has some control over her emotions. During the third season, the character no longer goes by “Skye”, and by the end is known as “Quake” to the public.
Leo Fitz and Jemma Simmons
Leo Fits is an agent of S.H.I.E.L.D. who specializes in engineering, especially weapons technology. The character receives brain injuries at the end of the first season, with the writers researching brain trauma with doctors and experts before approaching it in the series. De Caestecker did his own research as well, feeling it is “something that should never be trivialized. It’s a real and serious thing to a lot of people, brain trauma, so we just have to constantly be respectful towards it.” Jemma Anne Simmons is an English-born former S.H.I.E.L.D. agent and scientist. A genius biochemist, she is one of the youngest and most prominent members of S.H.I.E.L.D.’s research division, along with her partner and husband, Leo Fitz. She, along with Fitz were recruited to Coulson’s Team and worked with them on all of their missions.
