Biography

Events of Major Malfunction

To be written...

Events of WarGames

Immediately after switching seats with Collins, in the opening flashback of Ambush, O'Brien is shot in the head by a plasma blast. Later, in Deception, Spartan Louie Vargas and five repurposed protocol robots investigate the attack and discover O'Brien's dead body before Louie is shot and killed in a similar manner.

Trivia

• His appearance in WarGames differs from his appearance in Major Malfunction, as in the latter he wears a Recon chest plate with Security shoulder pads and various different helmets while in the former he appears with the CQB chest plate and Mark VI shoulder pads. This was due to series creator Syp The Mighty's desire for O'Brien to match the other head guards in Guard Duty, who have the CQB helmet/chest plate with Mark VI shoulder pads.
  • His secondary color was also changed, originally maroon in Major Malfunction before being changed to rubine for WarGames. This was simply due to Syp misremembering the color.
• He was voiced by Chron Aldazaar in Major Malfunction and later Avcracy in Major Malfunction II before Blankslate_GG was cast for WarGames and beyond.
  • Syp had actually contacted Avcracy, O'Brien's voice actor from Major Malfunction II, to reprise the role for WarGames but never got a response. Instead, Blankslate_GG took over the role.
• His first name is never stated in-series, with Syp coming up with it after the release of WarGames. During the production of the original Major Malfunction, its creators considered his full name to be Phillip O'Brian, with the spelling of his last name changing by the time WarGames was produced.
