Mainstream universe
(Capcom's primary storyline)

Regason Base was a military base in the US. Former Marine Lieutenant Billy Coen was to be sent to this base for his execution.[1]

Further notesEdit

The English dub for Resident Evil Zero mistakenly refers to the base as "Ragathon". This is because the sound "su" can replace "f" sounds in Katakana. Mark Reichwein's localization for Resident Evil Zero HD gives it as "Regarthon".
