Trivia

 * The match against Crash is an easy one; needing the first to five frags to win. The bot has a auto taunt program that every time you say something to her she says something random back. She is the only bot who does this, giving the impression of talking to the player.
 * As she only appears in Quake III Arena (canonacity to either the Doom or Quake series is unknown), Crash does not appear in any Doom game (except possibly based on the co-op multiplayer characters, essentially clones of the main character ). And is thus only known in Quake III Arena.
 * Quake Champions appears to set Doom (character)'s Quake appearances as part Doom Slayer complete history. Canonically Quake Champions is a prequel to Quake III Arena. The game also establishes that Doom Slayer is the same character from the original Doom Trilogy/Final Doom/64, as well as Doom 3.
 * According to Tom Hall, the Doom Marine is the descendent of William J. Blazkowicz and Commander Keen.
