Sunny was a visibly young girl with a petite build and short height; it appeared that she wore a light colored long sleeved dress in Connie's flashback. Her light hair is fairly long, going down to her shoulder blades and is kept tied back in a pony tail.

Clash of the Titans arc
Sunny is first revealed in a flashback by her brother Connie Springer in which he remembers her playing with their little brother Martin. During this time, Connie worries for Sunny's safety as he searches their village of Ragako looking for survivors after news that Wall Rose had been breached by Titans coming from the south, the same location as their home town. It is later revealed that Sunny was one of the Titan that were created by the Beast Titan after the events of Eren and Annie's brawl in Stohess District.
