Sailor Mercury uses Mercury Aqua Mirage, a move that she does not use in the original anime.
In the original series, Mimete died when she was forever trapped in the Witches Electric Warp by Tellu who pulled a plug on the machine.
In the original series, Sailor Uranus and Sailor Neptune made their first appearances long before Eudial or Mimete. Originally, Eudial did not appear until The Pure Heart Stolen! Usagi's Biggest Crisis (1994) and Mimete did not appear until Death of Uranus and Neptune? The Coming of Talisman (1994), respectively.
Sailor Uranus never directly destroyed any of the Witches 5 with World Shaking in the original series. She only destroyed a Daimon with the attack.
Mimete didn't pose as a Mugen student, nor was her civilian disguise as Mimi Hanyuu a celebrity in the original series. However, she did audition to become a celebrity.
