Mamoru (his name in the original Japanese) first appears in episode 1.
The Sailor Starlights, also known as the Three Lights, first appear in the fifth and final season of the Sailor Moonanime, known as Sailor Moon Sailor Stars in episode 173. This episode's title translates to "A Goodbye and an Encounter! The Destiny of Flowing Stars."
In both the anime and the manga, the sixth Sailor Senshi to appear is Sailor Pluto. In the anime, she first appears in in episode 75 (episode 68 in the English dub). In the manga, she appears in Act 18: Time Warp - Sailor Pluto.
I hope this helps but I know it was the first appearance of sailor v when Serena said we finally found the 5th sailor scout.
Sailor Moon and the rest of the scouts first meet the Heart Snatchers in episode 90. The target in this episode is Raye. In this episode, you also get a first glance at Sailor Neptune and Sailor Uranus. Also, Sailor Moon's transformation brooch stops working and she can't turn into Sailor Moon anymore.
Seiya first appears in episode 173 season 5 "A Farewell and a Meeting! The Flow of the Stars of Destiny" :)
She first appears in episode 173, and I believe she (or in the anime, he) is in every episode from 173 to 200 when Galaxia is finally defeated and she returns to her planet.
Episode 60 of the original uncut series. This is the first episode of the second ark (story) of the second season Sailor Moon R
Sailor Venus' first anime appearance is as Minako Aino, in a non-speaking role, in Japanese episode 33/or episode 29 in the English dub. She later appears as Sailor Venus speaking, at the end of that same episode.Her first appearance in the manga as Sailor Venus, and not as her previous "Sailor V" code-named identity is the final act of the Codename: Sailor V manga; her first appearance in the Sailor Moon manga is Act 8: Mamoru Chiba - Tuxedo Mask.Her first appearance in the live-action series Pretty Guardian Sailor Moon is Act 12.
I don't know which episode, but the Sailor Scouts get their Crystal Power in the Sailor Moon anime series "Sailor Moon SuperS," when Pegasus, the well, um, pegasus, arrives and updates Sailor Moon and Sailor Mini Moon's lockets.
She was in the very first episode.
I think episode 10 from the first season is the best because its the last episode with Jadite before queen beryl froze him but it was good to see his last fight with the sailor scouts.
episode 54 in English
