Well, here's my Sonic persona Paprika's reference sheet and "wiki page" bio, since y'all have probably been waiting for them...
Quick Note: Fleece the Sheep and Scruff the Goat belong to AngelLuvsPianoAndArt. Sonic and Nights into Dreams belong to SEGA. The other fanmade stuff belongs to me.

Paprika the Raven (カラスのパプリカ Karasu no Papurika) is a character in the Sonic the Hedgehog series. She is a resident of the seaside city of Beatbox City. She, despite what many around her think, believes that finding redeeming qualities in any evils is possible and hopes that finding them will help to better the world. She possesses an innate ability to shapeshift, which she can use to guide herself through a situation.
Born in uptown Station Square, Paprika lived her life trying to see the good side of the things she saw around her. After meeting Sonic the Hedgehog, Paprika and her friends put together Team Spice to help him combat against the forces of evil. However, having heard about Sonic's adventures, Paprika expressed distress over learning about his meetings with some of the enemies he faced. Paprika plans to use alternative approaches to change the way they perceive Team Sonic, with her sights set on the Zeti.

Paprika is an anthropomorphic raven with black feathers that span over almost all of her body. The only part of her body observed to not be black is her gray beak and her brown eyes. She has long, black hairlike feathers on her head, which is always tied into an updo, usually one that combines a ponytail and a bun.
Paprika's attire is various, but she commonly sports a light purple bodysuit, a lilac scarf and a light black leather jacket with a very large collar. She also wears plum purple gloves with matching shoes, each having almond soles and cuffs, white straps and light mauve ribbons designed on the backs.

At one point in Paprika's childhood, her parents adopted Puff, a chihuahua who can create clouds.
Paprika grew up in the city of Station Square, where she looked to find good qualities in the world around her, even through hard times. Throughout her childhood, she showed great skill in music and performing, as she was raised in a family who was passionate about musical theater. Later on, Paprika and Puff moved to Beatbox City, a city known for its liveliness and its fabulous taste in music, to pursue their dream careers, and they currently go to college there, where they met all of their friends.
Around this time, Paprika met siblings Scruff the Goat and Fleece the Sheep, who she became best friends with. She, Fleece, Scruff and Puff would then go on to form Team Spice after learning about Sonic's adventures and accomplishments.
Paprika, hearing about them, was touched by the fact that some of the villains Sonic fought were put through abuse and torment before meeting him. Desiring to learn more about them, Paprika decided to put her views to the test, and now she is looking to help the Zeti overcome their problems, make peace with her kin and be happy. She currently resides in an apartment complex in Beatbox City, sharing an apartment with Puff, and attends school at the city's local university.

Paprika is very compassionate, caring and good-natured, especially when she has a cause to be. She's very passionate when it comes to both doing good and the theater. In fact of the latter, Paprika is so theatrical that she literally lives out her life as if she is the star of a musical, singing whenever she's feeling her best. In spite of this, she knows when the time is right to put her choreographed musical numbers aside, such as when she's in a situation that doesn't call for them.
Her nature is very optimistic, upbeat and silly. She is the type to liven the mood if something is wrong, even likely to toss in a song. Seeing as her showtunes can go on for a while, though, her allies are hesitant when it comes to that.
Despite being a pacifist, Paprika can and will land a hit on someone or something at times when she absolutely has to. For example, she doesn't seem to have any trouble with destroying Eggbots and other evil machinery.
Even though she is generally sweet and bouncy, Paprika has a tendency to be a bit loud and talkative, which can make things uncomfortable for others. She's also a bit too blunt, randomly stating whatever comes to her mind a lot of the time.
Paprika has recently gained a fascination with Zeti, as she is pursuing a goal of helping the Deadly Six lead better lives, but not knowing where to start. She also wants to study the biology of the Zeti race.

Paprika's noted ability is her innate power to shapeshift, able to transform into any being she thinks of. Her most notable forms are her recent Zeti form, as which she calls herself "Zarmony," and her wisp form, which she mainly uses as means of blending in, calling herself the "Black Rhythm." She can also become other species such as cats, wolves, bears and small critters like Pickys and Flickys. However, Paprika's power only allows her to take the form of the species in question and not their abilities. For example, she cannot manipulate magnetic fields or use the Magenta Rhythm powers of her wisp form's type. With that said, Paprika also has trouble getting around as a wisp. Paprika is able to bounce from form to form, but only for limited times, as it becomes too much for her.
Being very skilled in music to the point where she can spontaneously sing and dance, Paprika can sing and dance really well. She's also a talented actress due to her "theater kid" attitude. Paprika can play piano, guitar, bass and drums, calling this talent her "one-man band."

Paprika's best friends are her fellow members of Team Spice. She met Fleece and Scruff around the time when they first moved to Beatbox City, sharing her love of music with Fleece and her quirks with Scruff. She is closest to Puff, so the two care a lot about and are supportive of each other. As a whole, Team Spice is a very cooperative group.
Paprika has a lot of other friends she enjoys being with, such as members of her class including two bird sisters named Poppy and Penny, buggish roommates Bobbi and Dolly, and a trout fish named Eulalee who lives in the same apartment complex as Paprika and Puff. She holds equal amounts of love for all of her friends, and even through pursuing her goals, she never turns her back on any of them. She also loves Salta the Chinchilla, a new friend of hers, who lives away from Beatbox City but still sometimes comes to see her.
Paprika serves as an ally to the main group, even doing computer work for the Resistance, as would be mentioned in Sonic Forces. However, she disagrees with them about a few things, seeing as they don't believe she can bring out good qualities in beings as malicious as Zeti.
