Dis boy is the firstborn of Applejack and Trenderhoof! He's a pretty chill dude with a charismatic voice. He wears contacts because he often accidentally broke his glasses as a colt. I don't really have anything else for him at the moment sadly OTL
But he lives with his ma and his sister on the Apple family farm! Applejack and Trenderhoof divorced years ago when Applejack discovered he was having an affair. Cosmic Crisp has two half siblings and a stepmother. He hasn't met the older of his half siblings, though from what he understands they were born before his younger sister Autumn was born. Cosmic Crisp wonders if they felt lonely growing up without Trenderhoof actively involved with their childhood.
He knows he feels a little lonely now that his father has a new family to devote himself to.
