A CIA man who takes a bullet for a Wakandan, is patched up in a country that does not officially have hospitals like that, and keeps its secrets for it.
Everett K. Ross is a CIA operative, and Martin Freeman plays him in four projects. In 2016 he is tasked with regulating members of the Avengers, and later with tracking down Ulysses Klaue, which is how he ends up in Busan taking a bullet for Nakia. He is taken to Wakanda for treatment, and after healing he helps prevent vibranium weapons from leaving the country as Erik Killmonger had planned. The reader who sent this list called him the secretary who has helped the Wakandans, which is the role he settles into.
In 2025 he secretly collaborates with Shuri and Okoye despite Wakanda’s political conflict with the United States, and is arrested for it by his ex-wife and now boss, Valentina Allegra de Fontaine. Okoye frees him.
Minor spoiler
In 2026 he is captured by Skrulls and held in Russia, and freed by G’iah.
