Rosa Sparkle Pie

Princess Twilight Sparkle would sometimes sneak out of Canterlot, away from her duties as Princess, to spend time with Pinkie Pie. One day, Twilight used a spell that created a child for the two. Her name was Rosa Sparkle Pie. Twilight could not raise the child because it was forbidden as Princess, so she had to leave Rosa with Pinkie. She used to be happy and kind, but due to being constantly bullied for being born an alicorn and for being the daughter of a "clown" (Pinkie), she moved to Canterlot to study magic. Here she discovered that Princess Twilight Sparkle was her other mother, which was how she was an alicorn. Frustrated, she killed her own parents, earning her cutie mark.

She's calm, quiet and likes to spend time on her own. She gets frustrated whenever someone mentions friendship or when she sees ponies simply frollicking around. Her personality is similar to that of Snowfall Frost's (before her reformation) and Moon Dancer's personality (before her reformation). She's a sadist, as she discovers when she kills her own parents and starts experimenting on other ponies. She can be slightly insane (acts like the fanon Pinkamena Diane Pie) at times.

Her body type is that of the average mare's. She has Pinkie's skin color and Pinkamena Diane Pie's (as in the depressed version of Pinkie) hair style (except the front is a bit shorter, similar to Maud's hair style) and Twilight's purple hair color with a few streaks of Pinkamena's hair color. She wears dark red glasses.
