WIP reference drawing for my DCA OC, Star. (Imagine she has hands)
It's kind of hard to tell from this picture, but her freckles are 4-point stars. Also, that half-circle at the bottom of her mouth is lipstick, not a tongue. Her swirly eyelashes are supposed to be the same style as the one that Sun and Moon have, but I may change them to straight eyelashes, like the ones used for the Star Orphans in SOTM (the glowing star baby things in the White Tiger section). I also think her outfit could use some work, especially the skirt (it was completely plain, but my sister helped me with the 8-point star pattern). I don't know if I'll ever put her in a story, but if I do, she'll look something like this.
As mentioned in this post, Star was supposed to be Sun and Moon's successor after they left the Pizzaplex. She was based on them and the Star Orphans. Her design was meant to be similar enough to Sun and Moon that guests could see the resemblance, while changing some of their less-popular features for more marketability. In the main timeline, her development barely made it to the concept art stage before Fazbear shut down, but there are some timelines when she was mostly finished before being abandoned.
According to Star's programmed backstory, she is Sun and Moon's younger sister who was sent to watch over the Superstar Daycare while they were away on an adventure. Like her brothers, she loves arts and crafts, gymnastics, and of course, children. As her ballet slippers might suggest, Star was also supposed to be a dancer, but they never had time to program or teach her how, so the only remnant of that part of her character are a few ballerina-themed voicelines.
When they find her, Sun and Moon are confused at why she exists, and even more confused that Fazbear suddenly decided their characters were related, but quickly accept her. Once they convince her that they are her "brothers," Star becomes overjoyed with seeing them after their long journey. Now sympathetic for their newest sibling, they decide to take her home and fix her up. They and their families work on her body and her mind until she reaches a more stable state, then they begin to teach her the fun stuff, such as dancing, playing games, and talking about things other than the daycare.
