Sailor Moon.

Serena (Sailor Moon)
is the main protagonist of the anime series of the same name. She is the leader of the Sailor Scouts and the moon princess. She is one of Pooh and Mario's best friends. She is very clumsy and a winer. She along with Rini, Amy, Raye, Lita, Mina, Amara, Michelle, Trista, Hotaru, Darien, Luna, Artemis and Diana will meet Pooh, Mario and all their friends in the Winnie the Pooh/Sailor Moon films. In Super Smash Bros for 3DS and Wii U, she will be set to be a new DLC fighter. Similar to Bowser Jr., her seven alternate costumes change the character's name and appearance to be one of the Sailor Scouts: Amy, Raye, Lita, Mina, Amara, Michelle, or Trista. However, they are otherwise identical to her.
