Hydronium Scandal

In May 2002, after the rights to S3K were acquired by Disney from Parakyo Films, the name "San'nin no heishi, hitotsu no ō" in Japanese was changed to the controversial, "heishi heishi heishi-o". This rebranding led newer fans to start shortening the name to H3O, this of course being another name for the Hydronium Ion. Due to this, new fans began referring to the anime as "Hydronium". In December 2002, Disney Studios Japan released the Heishi heishi heishi-o series.

This change caused backlash with original VHS fans who refused to call S3K by the new name and watch the new series. After multiple scandals and the relatively minor success the new series enjoyed compared to its predecessor, Disney discontinued the H3O anime, ironically leaving both S3K and H3O unfinished.
