Grant Ward

Agent Grant Douglas Ward is a major character in ABC series Marvel's Agents of S.H.I.E.L.D. He is the tritagonist turned true secondary antagonist in season 1 and an anti-hero in season 2. He is an agent of HYDRA who was one of many that infiltrated S.H.I.E.L.D. He strategically got himself placed inside a team of agents led by Phil Coulson and while he feigned interest and emotional investment in most of them, he developed genuine feelings towards Rising Tide hacker Skye. He answers directly to the Clairvoyant, who is actually his mentor at S.H.I.E.L.D. John Garrett. He has a very troubled childhood that rooted from tension with his family, particularly with the most trouble coming from his older brother, Christian. He's killed a number of S.H.I.E.L.D agents, including Victoria Hand and Eric Koenig. He has also indirectly tried to kill his former friends Leo Fitz and Jemma Simmons (although he technically saved their lives). Melinda May, his ex-lover from Coulson's team, defeated him in combat, partly fracturing his larynx and putting 3 nails in his foot. He's now imprisoned by Coulson in the Playground base, where he's giving HYDRA intel. He escaped custody while being transferred to his brother Christian, now an Anti-S.H.I.E.L.D. senator, as a peace-maker between him and Coulson. He tricked Sunil Bakshi into meeting him in a bar, run by a HYDRA agent. Grant killed his guards and left Bakshi tied up for Coulson. Then he kidnapped his parents and Christian and killed them, making it look like a murder/suicide on Christian's account. He then joined Daniel Whitehall, but secretly planned to bring Skye to her father, which he eventually did. After rescuing Skye, he was shot by her, but survived and escaped.

He is played by Brett Dalton.

Trivia

 * Even before his reveal in the episode Turn, Turn, Turn, he was seduced and turned evil by Lorelei two episodes earlier and ended up having sex with her.
 * Ward is similar to Agent 23 from Get Smart, as both are double agents who are secretly evil and eventually betray their teammates. However, whereas Agent 23 is the main villain, Ward is the secondary villain.
 * If you define the words in Grant's name individually, Grant means "great", Douglas means "dark", and Ward means "protector". Consequently, Grant Douglas Ward means "Great Dark Protector", possibly alluding to his true nature.
