The fact that Eclipse was even born was a surprise for his parents since they weren’t even sure they were capable of conceiving offspring together and in a way they were right. Eclipse wasn’t born in the normal way, since he was literally made from chaos magic influenced by Discord and Tia’s desire for a child of their own.

His hair’s quite strange in that part of it is just like normal hair while another part flows ethereally like his mother’s. With his father’s help, he’s trying to get the hang of controlling it, but struggles with it a lot. Sunburst and Starlight did make a magical golden hairtie that when he uses it, he has better control of which part of his hair has that etheral quality.

While he can go bipedal, he prefers going on all fours since he has some rather poor balance and doesn’t want to end up embarassing himself in public.

Often taciturn, only speaking much when he feels it’s needed or when he’s around those he’s close with.

Has astigmatism and dyslexia, but is ashamed of these since he wants to keep up the image of a flawless prince, even if his mother always tries to reassure him that he doesn’t have to keep pressuring himself. He does wear glasses to help with the former, but only complied with it since he figured it would make him look wise.

Because of their very similar personalities and the fact they can relate to each other, he’s good friends with Breaking Ground.

Is in a romantic relationship with Summersong, who he had known since his childhood. They were introduced to each other during one of Fluttershy’s visits to the Royal Family and the two became fast friends and often played together. Surprisingly to most, he’s the younger one between them.

Often tries to be very stern and serious, especially when it comes to court politics. He usually tries to set up marriage arrengements that are advantageous in any way (ie, alliances, power, etc.), with his many cousins often being the target of his attempts at political matchmaking. His cousins, meanwhile, have varying reactions to his attempts but often they’re annoyed especially since it does somewhat make him a hypocrite since he’s “essentially married” to Summersong out of love.

Capable of flight and magic, but prefers to not try them out of fear that it could lead to something dangerous happening. He had two accidents related to those things back when he was younger, and it’s scared him out of trying them ever again.
