Richard Aiken is the STARS' radio communications specialist and one of the Bravo Team members involved in the Spencer Mansion Incident.
In the original Resident Evil game, he is found on the east wing of the Mansion's second floor, severely wounded and poisoned by a giant snake. After a brief detour to collect antivenom, Richard dies, either after imparting information and a radio (if the player returns quickly), or prior to their return.
In the remake version, while playing as Jill Valentine, Richard will accompany the player into the fight with Yawn, sacrificing himself to push her away from a lethal attack, and being ingested by the snake. Whilst playing as Chris Redfield, Richard will be killed during the encounter with the shark-based Neptune monster.
In the novel Resident Evil: The Umbrella Conspiracy, Richard is found by Chris and Rebecca Chambers, already dead from the poison. In Resident Evil: The Umbrella Chronicles, Richard is a companion of Rebecca. He is one of the playable characters in the multiplayer mode of Resident Evil: Deadly Silence.
In the reboot film Resident Evil: Welcome to Raccoon City (2021), Richard Aiken will be played by Chad Rook.
