This page is a compilation of all known fan-made subtitles, fan-subs for short, for the Cybersix series.
There are no English subs that I know of.
I found this Brazillian Portuguese sub. It looks like it comes with softsubs for Portuguese and some English (like for the OP and ED), and English and French audio.
There are two Russian subs
- The first sub was uploaded online by anime-classic.org (looks like the website went down).
- The second sub is uploaded to YouTube by user Midnight_Max.
There is a Vietnamese sub uploaded to YouTube by user Ngọc Tân Bùi.
