text: on sailor moon who goes bad? like out of the good guys?  sailor scouts and what not... in the first season, mamoru/tuxedo mask was once used against the sailor scouts..   in the sailormoon r series, chibiusa was brainwashed by the black moon kingdom and was turned into black lady. she took mamoru, brainwashed him and they turned against the sailor team..   during the sailormoon s series, saturn's body (before she turned into a scout) was used against the scouts.   but they turned good once again.. no one turned completely bad or what-so-ever..
