Billy Coen/notes


 * When the armored Military Police car transporting Billy crashes due to a pack of Cerberuses, he manages to unlock one of his cuffs, effectively allowing him to escape. They dangle from his hand throughout the entire game, in the end Rebecca uses a spare handcuff key to take them off.
 * Billy is one of the few playable characters in the Resident Evil series that have not directly met the series' main antagonist; Albert Wesker, though Leon is aware of him.
 * Billy appears in two games; Resident Evil Zero and Resident Evil: The Umbrella Chronicles.
 * Billy is the only playable character in the series who cannot mix herbs.
 * Billy has two different official heights, as he is shown in-game to be 5'9", whereas the Japanese website for Zero lists him as being 5'11". His mass, however, is largely consistent. The difference of his height is actually created by a screenshot from the game. It shows on his ID paper that his height is "5 ft. 9in.".
 * Billy uses the only piece of profanity in Zero, exclaiming "shit!" as the Queen Leech finally catches up with the lift he and Rebecca are riding on.
 * Billy's tattoo is one of three references to the band Queen: "Mother Love" is the name of a Queen song, the same as "Made in Heaven" (from Claire's jacket in Resident Evil 2, as well as one of Chris's alternate costumes) and "Let Me Live" (from Claire's Jacket in Resident Evil Code: Veronica)
 * The Nintendo 64 version of Resident Evil 2, features a file named; Rebecca's Report. In it, Rebecca will detail finding Billy's body in the woods with the MP vehicle at the beginning of "Zero" (though his last name is mispelled as "Koen"). It also states that Bravo team was forced to abandon his body once they were attacked, and it was presumed lost. This was added in to the N64 version of RE2 to foreshadow the then upcoming RE0, also being developed for the N64, however it was later cancelled and development shifted to the GameCube.
 * During The NYC 2011 Comic-con, a Capcom representative answered questions regarding his status and he responded: " Billy Coen is still in the Resident Evil universe; we do have plans but nothing concrete so we can't confirm or deny Billy Coen returning back to the franchise because anything is possible."
