From left to right:
Pleased Aesthetic: Composed, proper, and calm, Aesthetic is the opposite of his daughter, which makes sense because he isn't her biological father. The two look nothing alike, and do opposite things, yet have a really strong bond. Probably because Shot is a hyperactive, positive little pony. Aesthetic is a magic school teacher down in Cantorlot, and his talent is using magic, and teaching it to young ponies. Since Shot is an earth pony, it was rather hard to get close with her at first. While growing up though, through love, he went to all of her soccer games. He is very positive himself, and goes by every rule in the book possible. He can be a little stern, but he tries is best not to be controlling.
Big Shot: Being Shot's biological father, he is one hell of a soccer player. He was very famous in his younger years, as they renamed Canterlot's home soccer turf under his name. His legacy moved onto Shot's, making the family duo very well known in the community. He is confident, yet humble, and knows his right from wrong. Mr. Shot is supportive, yet hard on Shot to do her best. She's so optimistic though, it's hard for her to break down. Mr. Shot it very patient, and trains her has much as he can. He loves his family dearly, but can come across as too pushy.
Hard Head: This athletic hunk is the offspring of Pleased Aesthetic, but he doesn't really look like him. At all. He got all his looks from the same surrogate as Long Shot, and for good reason. Hardy is a really tough, yet gentle dude. He is really good at football, and plays in a national league for Canterlot. He isn't really one for "family bonding", and absolutely despises his younger sister. Probably because he's jealous over how much his other dad paid attention to her, and only her. Hardy normally feels left out, and resorts to playing some ball with his buddies. He's really a softy, but doesn't come across that way in front of his peers.
