Scarlet Sunburn

THIS is Scarlet Sunburn. I mentioned her in Crimson Star's story, but here is more about her. Scarlet is the daughter of DayBreaker and Starlight Glimmer from an alternate timeline. In this timeline, DayBreaker has been ruling Equestria for a long time. One day, she learns about Starlight Glimmer's cutie mark free town. She knows the power one must have over others to, not only steal their cutie marks, but to convince them to follow her in doing so. She visits the town and "asks" Starlight to become her adviser or personal assistant or whatever. Starlight doesn't really have a choice, so she agrees, leaving her town behind to live in Canterlot, although she visits is occasionally to recruit new members and keep things in order. DayBreaker and Starlight work together for a long while before DayBreaker confronts her on working together to try and create an heir. DayBreaker had found an old spell for making a same-sex offspring and thought Starlight to be the only one smart enough to try this with. Again, not left with many options, Starlight agrees, and they create the most powerful Unicorn child whom they name Scarlet Sunburn. Scarlet Sunburn is as evil as evil gets. She gets her cutie mark in leading ponies into war and creating explosives. Both of her parents are very proud of her. One day, her cousin, Crimson Star, jumps to her dimension. DayBreaker, now knowing that there are other dimensions, especially one in which her sister rules, orders her daughter to fight Crimson Star and take control of his powers. Daybreaker wants to control all dimensions and to do that needs to control her nephew. The two cousins have an epic battle, but Crimson eventually gets the upper hand. Crimson later revisits the dimension, knowing DayBreaker would stop at nothing to try and take over the multiverse. He foils her plans, which angers Scarlet. As a last ditch effort, Scarlet follows him back through his portal and into the canon universe to take over the canon world in the name of DayBreaker. She fails, and Crimson Star refuses to return her to her timeline, at least until she is reformed. It takes Scarlet a LONG TIME to become reformed, but she eventually learns to accept things how they are. She ends up fallowing in love with a changeling: Beetle Juice. Beetle Juice is super nice to her and makes her let her guard down. The two have kids together and being a mother changes Scarlet Sunburn. Crimson Star eventually offers her a chance to go back home to her true timeline, but Scarlet denies him, saying she liked her new life and didn't want to be used for war anymore. She also wants to be prepared to a time DayBreaker figures out how to do dimensional jumps without her and will be here to protect her family.  There is more too this, but I'm still figuring it out.
