Selena is a female mountain dragon who first appeared as a playable character in Super Mario Galaxy 3.
Selena is generally an easygoing character. She enjoys the 'simple pleasures of yesteryear'. She is friendly to those she cares about, but does not take any prisoners when it comes to defeating the Koopa Troop. Selena is more than happy to help Mario on his journey, and gives him a hand when he is fighting in Bowser Jr.'s Star Striker.
Selena's native realm is a castle known as Selena's Dragon Dungeon, a cool, peaceful place inhabited by several Toads. She took responsibility for teaching her Toad neighbors certain tricks to survival and does her best to protect them from harm - and from each other's tricks.
- Selena is the only playable character to be a female.
