The way the Ultimare Universe works is “every core character is mostly the same, but everyone’s swapped personalities with each other. Also it takes place in Manehatten.”

Sparkling Cider (Applejack) is a composed, sophisticated businessmare, who develops and markets a wide range of products derived from apples. Apple-scented candles, apple-based body lotions, etc. Mulled Cider (Big Macintosh) is a beatnik poet and artist, complete with black sweatshirt, beret and tiny glasses. Madam Applecrest (Granny Smith) is a world-famous graphic designer and food critic. And Apple Spritzer (Applebloom) is basically Eddy from Ed, Edd n Eddy.

Ivory (Rarity) is a shredded blue-collar gem miner. Never seen in a dress, only overalls, workout clothes, sweatsuits or actual suits. Utterly lacking in social refinement, but has abs you could grind meat with. Naturally, she and Sparkling Cider are in a relationship. (In fact, this whole AU only exists so that its creator could double up the amount of rarijack he was mainlining every day.) Marble (Sweetie Belle) wants her big sister’s respect and to go down into the gem mines with her. Considering her complete inability to even lift a pickax, let alone swing it, neither of those goals are likely to happen anytime soon. Her friendship with Apple Spritzer isn’t a natural result of compatible personalities, but a result of exterior factors. Specifically, the frequent occurrence of them being forced into contact with each other as a consequence of their sisters relationship. Marble’s strong moral character and work ethic frequently clash with Apple Spritzer’s more opportunistic and mercantile attitude towards life.

Ink Blot (Pinkie Pie) is a newspaper cartoonist who publishes under a pen name and only leaves her apartment when necessary, because she’s shy and introverted to the point that she might legitimately be neurodivergent. She actually possesses the same musical talent as the rest of her family, her parents Clef Rock (Igneous Pie) and Parsley Sage (Cloudy Quartz), and her sisters Cashmere (Marble), Izzy Rock (Maud), and Decibelle (Limestone), but the thought of performing in front of an audience causes her to stop breathing. Her equivalent to ‘Pinkamena’ is a being referred to as ‘Ink Splotch.’

Cottontail (Fluttershy) is an irrepressible ball of creative energy with a huge fixation on animals of every kind. Instead of taking care of animals, she’s constantly making new costumes in order to pretend to be them. She also greatly enjoys making stuffed dolls of animals, and then sneaking into ponies’ houses to leave them on the nightstands of foals (while dressed as a raccoon, of course.) Growing up she wasn’t allowed to have a pet, so she made her first stuffed animal to fill that space. A battered winged rabbit she called ‘Bunny Angel’. The only animal she isn’t allowed to dress up as except in extremely dire situations is the bear. Cottontail bringing out The Bear is very much a ‘we have reached DEFCON 1’ thing.

Prism Wing (Rainbow Dash) dreams of coordinating the greatest Wonderbolts routines ever seen. In fact she has more than enough talent and skill to be the best flyer ever herself, but she’s too much of a neurotic control freak to ever try. Her meticulousness and adherence to procedure make her an excellent organizer of Manehatten’s weatherponies, but she doesn’t cope well with having to throw the book away and figuring it out as she goes. She also has serious anxiety and self-image problems. Her current pupil is Manehatten street kid Plume (Scootaloo), who seems to be under the impression that she’s some kind of anime protagonist. She puts on an image of extreme ‘too cool for school’-ness to mask how unhappy and alone she really is, as her inability to fly thanks to having wings too big for her flight muscles to move has made her an outcast with every one else in her age group (except for her fellow Manehatten City Mavericks, Apple Spritzer and Marble.)

Stardust Nova’s (Twilight Sparkle’s) skills with all things magic is matched only by how great she believes she is and her desire to apply the spells she finds to real-life situations. Specifically, situations like the faces of monsters. A professional monster hunter, Spyke (Spike) entered her life when Princess Celestia charged her with bearing the consequences of slaying a dragon in order to earn a spot in Celestia’s monster hunter program, by tending to the single dragon egg that survived the battle. Everyone thinks the Captain of the Guard received his bad-ass facial scars from fighting some great evil. Actually, it’s because he had to grow up with a baby sister who is both a magical prodigy and someone with abysmal trigger discipline.

@Tragiclady  
No, he’s just still a dragon, but more combat oriented, since Twi is a monster hunter.

I’m not familiar with this setting. Is this version of Spike a firebender?
