Steve Burnside (スティーブ・バーンサイド, Sutību Bānsaido) (voiced by Bill Houston, Sam Riegel in The Darkside Chronicles) is Claire Redfield's partner in the game Resident Evil Code: Veronica. Steve was imprisoned in the Rockfort Island's facility alongside his father, a former Umbrella employee. He escapes from his cell during the viral outbreak. At first, he is hesitant to trust Claire and only cooperates with her reluctantly. Later however, Steve becomes more open and attached to her after he is forced to kill his own father, who has become a zombie during the outbreak. Steve and Claire eventually end up in Umbrella's Antarctic Facility, where he is captured by Alexia and used as a test subject for the T-Veronica virus. Claire meets a chained Steve, who mutates into a monster and attacks Claire; in this form, he is nearly invulnerable to damage, and wields a giant, ceremonial axe. While running from Steve, Claire is attacked by one of Alexia's tentacles. Steve, seeing this, regains control of his mind and cuts the tentacle apart, freeing Claire. In retaliation, Alexia strikes him with one of the tentacles, inflicting a mortal wound. His failing body finally rejects the mutation, and he changes back. He dies in Claire's arms, just after professing his love to her. He was later taken by Albert Wesker due to the T-Veronica virus in his body, and also hinted that he might come back to life. In 2002, Wesker contacted Javier Hidalgo and took a sample of T-Veronica from Steve's corpse in order to provide the virus for Hidalgo's ailing daughter, Manuela. In exchange, Wesker was given a large sum of money and a stake in Hidalgo's crime operation.
