Boromir

Agent Boromir is a native of Arda, a former member of the Fellowship of the Ring, and a member of Team Phoenix.

In Lord of the Rings
Boromir was the son of Denethor, Ruling Steward of Gondor. Had things gone differently, he would have assumed his father's place as ruler of the city and kingdom. However, things did not go different. Boromir joined the Fellowship of the Ring, stayed with them until they reached Rauros Falls, and then tried to steal the One Ring from Frodo Baggins. A short time later, he got turned into an oversized pincushion by either one (Movieverse) or many (Bookverse) Orcish archers. Then he died.

In Fanfic
Boromir is either a foam-brained Lust Object or a misogynistic rapist.

In the PPC
Boromir was recruited, along with five other characters who had been portrayed by Sean Bean (and one who portrayed Sean Bean's brother, because Callahan rather thought he got the short end of the stick), by Agent Kitty Callahan. Together, these seven males formed Team Phoenix.
