Sunny is a kind, optimistic and bright mare who has a passion for studying the past and learning about the history of friendship, along with a strong determination for uniting ponykind.

Her passion for bringing different creatures together made her the target of extreme criticism and social exclusion for much of her life. But a positive attitude and a few good friends helped drive her to the day she reunited most of ponykind.

For the most part, she is an ordinary individual who works at a smoothie stand, roller skates, and loves spending time with her friends.
