When creating an OC, it's always important to make them feel real and make sure they fit into the land of Equestria. However, if said OC is a sibling of a canon character, you have to go a step further and make them look and feel like an actual sibling that said character would have. You'd have to work harder to get people to buy your character.

This is the home for any OC that happens to be the sibling of a canon character. Whether it be a major, minor, or background pony, it doesn't matter who your OC is the sibilng of. It can be part of this group.

So... show us those lovely OC Siblings!
