Outlaw Star (partially lost Toonami re-edited version of English dub of anime; 2001)
In 2001, an edited version of the anime Outlaw Star was broadcast on the American Cartoon Network. The show had new lines recorded and footage digitally edited in order for the show to receive a "TV-Y7" rating.
While the majority of Toonami's edited versions such as Blue Submarine No. 6, Gundam Wing, Yu Yu Hakusho and Tenchi Muyo! were released in edited formats on home video, this edited version was never officially released on VHS or DVD for unknown reasons, leaving it lost to time. One possible reason for this may be because of errors in editing that occurred during the initial run, such as the word 'bastard' slipping through in one episode. However, it was broadcast on Adult Swim in 2002.
There have however been reports of people receiving the Toonami edited version on bootleg DVDs, as well as the edited dub of the episode "Maze of Despair" playing as part of the Toonami April Fools event on Adult Swim on April 1st, 2012. Another episode was found via a recording on the Internet Archive. The edited version of episodes 6 and 19 were found via recordings of the Adult Swim broadcasts.
Update: In 2019 most of this lost media was found. It's not all there though. Check the notes below the links for more information.

Episode 18 is missing its first half (approx.) meaning that episode should still be considered lost.
Episode 23 wasn't originally aired due to its explicit content but was during Toonami's return with some censorship, so that needs adding when found.
Episode 24 is missing a short (and probably unimportant) part of its ending.
Episode 25 was recorded on VHS and was also recorded from a Toonami broadcast that was a 2012 April Fools' joke. Both are provided because they could be censored differently.
Episode 26 has been recovered from different VHS tapes. Because there may be differences (sometimes Bandai overlooked swears and altered the censoring for subsequent broadcasts) both recordings are provided.
All episodes except 1, 25 (only the April Fools' one) and 26 are missing credits and thus the "Next Time" segment. (Obviously, there isn't that segment for episode 26 but it does have the extra scene after the credits.)
