Nemo is Heart's twin brother and like him, he also received the same gifts his brother did. Although Nemo is Heart's twin, he sees Heart as an older brother, and Heart sees Nemo as his younger brother.
Nemo is a bit more outgoing than his brother. Never afraid to show it off, he'll indulge himself in the looks and stares of colts and fillies alike.
He got his name from the movie "Little Nemo", which was a running gag between him and his brother so much he decided to go by the name as a nickname.
