Alan

Alan is an alien from a planet, of which he and Anne are the last survivors. He and Anne are the antagonists of the first 13 episodes of Sailor Moon R, although they were far more misguided than truly evil. He has blue hair, and a stripe of pink on his bangs each side of his head. He played the lyre.

Alan and Anne came to Earth sometime after hearing about it from Queen Beryl, as they needed energy for the Doom Tree. Alan and Anne sent Cardians to drain energy from people to give to the Doom Tree. This forced Luna to restore the memories of the Sailor Scouts so they could fight them.

While he and Anne were posing as humans at Serena's school, Alan fell in love with Serena. Anne did not know this at first, nor did he know that she was in love with Darien. They soon found each other out in Episode 4.

At one point, Lita fell in love with Alan, and Anne sent Cardian Mophead to attack them.

Alan wanted to play Prince Charming in the play, but was disappointed that Darien was Prince Charming and Anne was Snow White, so he sent Cardian Pierrot to crash the play.

When Serena and Anne got put in detention, Alan summoned a Cardian named Insectia who disobeyed him, jumping on his head, and even attacking ducks, until she was destroyed.

Eventually, Alan and Anne's identities were revealed to the Sailor Scouts, and they fought at the Doom Tree. Alan and Anne had the advantage, but Alan began to realize that what they were doing was wrong, seeing Serena with Darien made him realize the true power of love. Anne, however, did not, until the Doom Tree attacked Alan, and she jumped in front of him and took the hit, getting stabbed by one of the Doom Tree's vines, killing her.

After the Doom Tree told them that it needed love energy to survive, and that Alan and Anne's people were corrupted by the Negaverse, the Doom Tree was healed by Sailor Moon, and brought Anne back to life. Alan and Anne left Earth with the Doom Tree to start a new and better life somewhere else.

Both Alan and Ann attack with a powerful gravity blast that puts painful pressure on their opponents.

Trivia

 * Alan bears a strong resemblance to Fiore, a character that only appeared in the Sailor Moon R movie including similar color schemes matching hair color and style color palettes. Despite being almost identical, Fiore was never officially stated to be the same race.
 * Alan's pan flute melody was also used in "Dog Day for Artemis" and in the Sailor Moon Super S movie "Black Dream Hole", as the audio mixer of the final part of the second season on-wards had no involvement with the series in the first 65 episodes.
 * In the original Japanese, Alan and Anne (Ail and An) were introduced as completely new enemies with no connection to the previous enemy. In the first dub, they are associated with the Negaverse and heard of earth from Queen Beryl.
