In this episode, Tuxedo Mask uses Tuxedo La Smoking Bomber, a move he does not use at all during the original series. In Sailor Moon (1992), Tuxedo Mask never had any other types of attacks, other than hurling red roses at his enemies to immobilize or weaken them.
In the original series, Calaveras could not channel spirits of the dead but used an energized whip as her main weapon.
In the original series, Mamoru never had the four colored stones that had contained the spirits/souls of his four devoted servants - Kunzite, Zoisite, Jadeite and Nephrite - nor did they appear again after the first season.
In the original series, Calaveras did not perish at Sailor Moon's hands but was reformed as a human woman alongside her three sisters by Sailor Moon's healing ability, Moon Crystal Power from the Silver Crystal.
Sailor Venus uses Rolling Heart Vibration, a move she does not use at any point during the original Sailor Moon (1992) series.
