Richard Aiken (リチャード・エイケン,Richādo Eiken?) was a member of the Special Tactics And Rescue Service, serving as the S.T.A.R.S. Bravo team communications expert.[notes 1] On a personal level, Richard is described as being a "positive, sweet guy", who, despite his relatively young age, is "surprisingly cool-headed and calm under pressure". He always greeted new S.T.A.R.S members warmly. His weapon of choice was his customized assault shotgun.
Before the start of the July 23 mission to investigate the mysterious deaths in the Arklay Mountains, Richard was entrusted with taking care of the new recruit, Rebecca Chambers. When Bravo Team was stranded in Raccoon Forest, the team was attacked and Richard, along with most of his teammates, managed to make their way to an apparently abandoned Spencer Mansion, but scattered when they found it filled with undead.
Richard found Rebecca sleeping in a remote bedroom in the nearby dormitory. Richard comforted the youngest member, assuaging her fears and gaining her assistance in an attempt to locate Enrico Marini, their captain, in the hopes of making a plan to escape the mansion or summon help.
The two proceeded throughout several areas of the mansion and grounds, desperately seeking Marini. Eventually, the two were attacked by a giant snake. While they were successful in driving the beast away, Richard took Yawn's final attack to spare Rebecca. Richard was bitten on the side and thrown through the air before the beast slithered away. Rebecca dragged a poisoned and severely injured Richard to the mansion's east-wing.
While being nursed by Rebecca, Richard is discovered by Chris Redfield. Rebecca informs Chris of Richard's situation and requests a serum to cure him. Not wanting another friend to die, Chris obliges and tracks down the serum, handing it over in time to allow Richard's survival. Before he passed out, Richard gave Chris his short-wave radio. The radio, however, was broken and could only be used to receive S.T.A.R.S. Alpha team's pilot Brad Vickers's transmissions. Richard was then taken to the storage room to rest, while being watched by Rebecca.
After recovering, Richard made his way to the Aqua Ring, but was surprised by Neptune. Richard warned Chris, who just entered the ring. Richard noticed Neptune advancing towards Chris and pushed him away from the danger, being killed by the shark in the process.
After his death, his lover, Bridgette, read aloud a letter he wrote to her at the RPD's joint funeral for the Alpha and Bravo Team casualties.
