The men Minako has loved

Alan (episode 42)

Alan was Minako's love from England. She loved him, but he only saw her as a friend. When Minako discovered Alan loved her friend, Katarina, she left. But then, Katarina and Alan came to Japan 6 months later, and Minako was reliving her past. Then, Kunzite attacked Katarina and turned her into a monster, but Sailor Moon healed her back to a human. After saving Katarina, Minako accepted the fact that Alan loved Katarina.

Haruka Tenno/Amara/Sailor Uranus (episode 92)

Before find out Haruka's gender, both Minako AND Usagi had a crush on Haruka, whom they thought was male. They were sneaking around, seeing this "boy" with Michiru/Michelle/Sailor Neptune and got jealous and wanted to see who "he" was like. At the end of this episode, they were both shocked to find out Haruka was really female (she looks just like a man, though).

Tiger's-Eye and Hawk's-Eye (episode 141)

In this episode, Minako fell for two guys at the same time, Mr. Torajin (Tiger's Eye) and Mr. Takano (Hawk's Eye). At times, she kept two-timing to date both of them at the same time (oooh, Minako...). But then they revealed themselves as Tiger's Eye and Hawk's Eye and then they stole her Dream Mirror. Fortunately, she got her Dream Mirror back and joined her friends to fight the Remless sent by Tiger's Eye and Hawk's Eye.

He gets a new show and Sailor V is forgotten because of him. He claims to help girls and is a girl's best friend. And with that, Minako falls for him. Not only does he play Kaitou Ace on TV, but as him in real life and helps Sailor V with her missions. Eventually, Minako gets to win a part in a movie with him. Sadly, she finds out he is also really Danburite, the leader of the Dark Agency (which also works for Queen Beryl and the Dark Kingdom). He also reveals to her that he is the reincarnation of Adonis, her lover from her past life as Venus in Magellan Castle. As he lay dying, he told her that she will forever have her duty as a Senshi over love. This is sadly, a case of a love not meant to be
