ChibiSusan

ChibiSusan is a small\chibi\child version of Susan Wainwright. Thus she can be considered to be part of the Wainwright and Bronte families and potentially be called ChibiSusan Wainwright or ChibiSusan Bronte but mostly just ChibiSusan.

ChibiSusan's backstory can vary but she is separate from simply Susan Wainwright as a child.

ChibiSusan's main gist is that she is a child doppelganger of Susan created by the Fovix-Nyaat from another plane of existence. She was sent to live with Susan and have adventures with her. She considers Susan to be her mom and Blair to be her sister. Boyd is either her dad or uncle depending on the ship.

ChibiSusan is loosely based on Chibiusa from Sailor Moon, but also on Kairi Bronte, which was Susan's clone in one of my old Sims 3 savefiles.
