Rikki was born to her dad Terry and unnamed mom who later died during Rikki's early childhood. Terry made it a tradition to celebrate his late wife's birthday so Rikki would always have a connection to her which she eventually became sentimental of. Rikki grew up in Dolphin City and became friends with Cleo, Emma and Lewis. Rikki has a light skin tone, red-brown eyes, and wavy/straight bright red hair.

Her usual outfit, as a human, consists of a white button-up blouse with a single tone shirt underneath, rolled up cuff capri pants, and red and white sneakers.
