  [[Leo the Lion|Leo the lion]] holds the distinction as being both [[Neflite|Nephrite]]’s and the [[Negaverse|Dark Kingdom's (Negaverse’s)]] first male [[youma]]. He also holds the distinction of being the first [[youma]] assigned only to kill [[Sailor Moon]]. To achieve this, [[Neflite|Nephrite]] sought approval from [[Queen Beryl]] for his plan to impersonate and don the appearance of [[Tuxedo Mask]] so he could exploit [[Sailor Moon]]'s “foolish love" by luring her into a trap and learn of her true identity <ref>[http://soul-hunter.com/sailormoon/profiles/villains/motd/shishiza.php - The Oracle (Shishiza)]</ref> before killing her. As part of his plan, [[Neflite|Nephrite]]’s mails bogus love letters to junior high school students with certain areas of [[wikipedia:Tokyo|Tokyo]] (including [[Sailor Moon|Usagi (Serena) Tsukino]] and [[Sailor Mars|Rei (Raye) Hino]]). Unfortunately, his plan fails when one of the high school student's, ([[Naru Osaka|Naru Osaka (Molly Baker)]]) questioned [[Neflite|Nephrite]], asking him if he was behind the distribution of bogus love letters to the female students. Suspecting that she was [[Sailor Moon]], [[Neflite|Nephrite]] “led her on” to test if she would walk into his trap at the Shinjuku MS Department Store. Not only did [[Naru Osaka|Naru Osaka (Molly Baker)]] correctly figured out that [[Neflite|Nephrite]] wrote the bogus love letters but was naive enough to attend the Shinjuku MS Department Store attend earlier than expected and recognise [[Neflite|Nephrite]]’s alter ego inside the [[Tuxedo Mask]] disguise. After confronting her in his [[Tuxedo Mask]] outfit demanding that she “reveals herself”, he drained all of her love energy despite the latter pleading that she was not [[Sailor Moon]]. "When the masquerade was exposed after he was discovered draining [[Naru Osaka|Naru Osaka (Molly Baker)]] of her energy by her best friend [[Sailor Moon|Usagi (Serena) Tsukino]], she quickly changed into [[Sailor Moon]] to confront [[Neflite|Nephrite]]<ref>[http://www.fortunecity.com/rivendell/everquest/90/L/leo1.html - The Ultimate Sailor Moon Encyclopedia (Leo)]</ref>", "at which point the two long-time adversaries finally met face to face <ref>[http://ww.fortunecity.com/rivendell/everquest/90/N/nephrite.html - The Ultimate Sailor Moon Encyclopedia (Nephrite)]</ref>"! Once Nephrite fully revealed his true identity to [[Sailor Moon]], he scares her with an illusion of his clones before creating an illusion of the star [[wikipedia:Regulus|Regulus]] to whom he calls upon its power. The illusion of the star transforms into the constellation of [[wikipedia:Leo|Leo]] within which the [[youma]] of the same name leaps out and begins chasing after [[Sailor Moon]]. Had it not been for [[Tuxedo Mask]] striking Leo the lion on his face, [[Sailor Moon]] would have been fatally wounded. Returning his favour, [[Sailor Moon]] helps [[Tuxedo Mask]] battle Leo the lion with her [[Moon Tiara Magic|Moon Tiara]] attack, only for it to fail her as it merely stuns the [[youma]].  "Upon recovering, the [[youma]] continued his pursuit <ref>[http://www.fortunecity.com/rivendell/everquest/90/L/leo1.html - The Ultimate Sailor Moon Encyclopedia (Leo)]</ref>" of [[Sailor Moon]] and [[Tuxedo Mask]]. He is recalled by [[Neflite|Nephrite]] after he successfully traps the retreating [[Sailor Moon]] and [[Tuxedo Mask]] inside an elevator rigged by [[Neflite|Nephrite]]. However, both [[Sailor Moon]] and [[Tuxedo Mask]] escape from [[Neflite|Nephrite]]'s trap and certain death with the help of [[Sailor Mercury]] and an ill [[Sailor Mars]].

  == Trivia ==
  *He is the only undefeated monster of the week in the entire anime. It is possible, however, that he may have been destroyed along with the [[Negaverse|Dark Kingdom (Negaverse)]] (along with the other unnamed and unused monsters) when [[Princess Serenity]] destroyed [[Queen Beryl]].
