Now that the finale happened I wanted to include ships that were (kind of?) canon. Just wanted to design colorful horses again.

Nightfall (TwilightSparkle x TempestShadow)
Nightfall is a scrappy little ball of anger. She's not really good at friends and doesn't really have any interest in getting better. But she's constantly surrounded by cheery ponies who want to be her friend. She'll never admit it but she does like their company and being around them. She gets very protective when others mess with them.

Lil Cheese (PinkiePie x CheeseSandwich)
Lil Cheese inherited twice the chaotic party energy from their parents. They come off really intense but much like Pinkie and Cheese, are adored for their intensity. They don't really talk much but find other ways to make ponies laugh. They are particularly good at prop comedy.

Zapple Cider (RainbowDash x Applejack)
Zapple Cider is just as energetic and spunky as her parents but not the least bit competitive. She often shies away from competition and isn't very driven. She enjoys doing things at her own pace which can sometimes be a good thing and can sometimes be a bad thing. The zap apple harvest is her favorite time of the year.

Selenite (Rarity x Luna)
Selenite is a calm, prim and proper princess. She's rather quiet and tends to keep to herself. Despite this she's still incredibly dramatic like her mom, Rarity. Her dramatics take the form of brooding. She can often be found staring out a rainy window, trapped in her own head. She's fascinated by precious stones and enjoys helping Rarity around her shop. She also spends a lot of time with Luna, who is now retired.

Hoover (Fluttershy x Discord)
Hoover is just a regular earth pony. Not even a pegasus like his mom. Just an earth pony. He also doesn't appear to be able to get a cutie mark. His parents were very confused when he was born as they were expecting hime to be some sort of demigod. As he grew they waited to see if he'd show signs of having chaos magic or any magic at all. But no. He's just a pony. Which is probably the most chaotic thing of all given the circumstances.

Cinder (Spike x Ember)
Cinder was born and raised in the Dragon Lands. He's a bit of a troublemaker and quite sarcastic. He likes to act big and tough but he's really a kind soul. He's very interested in pony culture and likes to go visit whenever he can.

Phoenix Feather (Celestia x Novo)
Phoenix Feather is an incredibly passionate (and powerful) young prince. He has his heart set on being a ruler one day. He spends a lot of time shadowing Twilight Sparkle or his mother Princess Novo, learning how to be a leader. While Celestia is supportive of this, she's worried that Phoenix isn't living life to the fullest. Since she's retired she makes sure to travel with Phoenix and get him to relax every once in a while. Phoenix and his older sister, Skystar, are set to rule Seaquestria and Mount Aris. But seeing how Phoenix is deathly afraid of water, he'd prefer to rule Aris.
