Onion boy has joined the server!
 
When Orion was first born and Celestia and Luna were introduced to him, the sisters misheard their mother when she told them his name, so instead of calling him “Orion” they genuinely believed his name was “Onion” the first few months of his life. That nickname never really went away, so when they were alone with each other they’d just call him Onion.
 
Had some free time to finally doodle the three siblings as young and the two elder sisters still being curious about this new baby brother of theirs. If I’m not too busy with other things I’d like to draw some more stuff with these three, such as their young adult/fully grown selves. I’d like to explore some of their color schemes and bodytypes more. Celestia is a lot like her mother with being very tall, skinny and frail. Luna is more like her father with a shorter, heavier and more muscular build. Orion is a little inbetween the two, but leans more towards his mother’s thinner frame.  
I know that in their famiyl tree, their manes are more flowy and have different colors. An alicorn’s powers grow more and more over time, and when it’s time for them to take over after their parents, their physical appearance can change. One of the things that changes the most is their mane, which begins to move and flow the more power they gain. Things like fur patterns, feather patterns and horns can also change.  
So in the future, Celestia’s will turn more fire-like, Luna’s mane will turn more mist-like, and Orion’s mane will turn more galaxy-like.
 
EDIT: Forgot to draw their tailfeathers, jinkies
