Character Synopsis:
Briana Gem Sentry was different from most girls. With no memory of her past or biological family, Briana was raised by a family of mutants once her older siblings found her in the sewers and took her in when she was only a baby girl.

As she grew up, Briana was known to be the very glue that held her family. The bubbly little girl was always putting her loved ones' happiness before her own happiness, always hiding her thoughts and doubts from everyone. Like all adopted children, Briana wrestles with the one question that any adopted child feels:

Why would anyone give her up?

As she struggles with the question everyday, Briana would sneak out of the lair to see the lanterns covered the pitch black sky that always appear in the sky on her birthday as she always felt like the lanterns were for her.

On her older siblings' 15th birthday, her adoptive father and teacher finally lets the six of them to leave the lair and venture to the topside where they see the wonderful sight of New York City. At last, this was where all of their adventures were finally starting to happen.

But when Briana meets a boy with the name Cameron Chandler [OC owned by @MariChat3] who is said to be from the same place that she's from, Briana may just be able to learn more about her past and her biological family. But what Briana doesn't realize is that those secrets were kept hidden from her for a very good reason as she will learn that she has a prophecy hanging on her shoulders as she will need to finish the final battle with the one known as the Dark One in order for Briana to become the Destroyer, thus fulfilling the prophecy that was placed on her since... her decreased grandmother, Twilight Velvet was never able to finish it.

As more secrets are being brought out to the light, Briana has to answer one question for herself.

Does she realize who she truly is or is she nothing more than a villain and monster from the prophecy with all that darkness she holds inside of her?

The very villain and monster that parents and their children are afraid of?

Her Demon Side's Nicknames:
Unagami [by her parents and brother]
Princess of Darkness [by her parents' minions and any other demons]

Her Demon Side's Age:
114 [in demon years]

Her Demon Side's Family:
King Derek of the Underworld - biological father.
Queen Lilith of the Underworld - biological mother.
Prince Dread of the Underworld - biological older brother.

Unagami's relationship with her family:
King Derek of the Underworld - father. Unagami has a rocky relationship with her father since all Unagami ever wanted was to make her father proud and helped with his plans to take over the world but it was never enough as Unagami dealt with the consequences of her punishment, taking the abuse and torture from her father. This relationship becomes even more strained when Unagami escapes to the real world with her brother in order to take over the world for herself.

Queen Lilith of the Underworld - mother. Unagami has a rocky relationship with her mother since Lilith has tortured her physically and mentally her whole life. This relationship becomes even more strained when Unagami escapes to the real world with her brother in order to take over the world for herself.

Prince Dread of the Underworld - older brother. Unagami and Dread were once close and the two demon siblings grew closer when they escaped to the real world together to get away from their parents. However, as years passed, the bond between Unagami and Dread became strained when Dread came to discover his sister's plans of taking over the world for herself but the two demon siblings officially grew apart when the two were pulled into their vessels [Unagami with the Velvet family and Dread with the Riverstone family] by force due to Dread being the one that got them caught. Luckily, it would be thanks to Briana that Unagami is able to fix her relationship with her brother that the two demon siblings are able to be close again.

Unagami's relationship with her vessels:
Kira Velvet - decreased former vessel. This relationship was a rocky one as Kira only used the magic to her own advantage to torture others and terrify them in doing her own doing, seeing the demon as nothing more than a weapon.

Queen Twilight Velvet - decreased former vessel. This relationship was a rocky one as Twilight Velvet attempted to try to make Unagami her friend and ally but Unagami refused and attempted to take control over the woman's body and trying to scare the woman into giving her control but Twilight Velvet refused, putting the two at constantly odds.

Briana Gem Sentry - current vessel. This relationship starts off as rocky with Briana being afraid of Unagami and her destiny while Unagami attempted to take control of the girl's fear in order to gain control over her body. But as time goes on and once Briana slowly starts to learn how to control her magic and gets over her fear, Briana will manage to turn Unagami from a enemy into a friend and ally.

Personality:
Briana is very bubbly, stubborn, kindhearted, loyal, trustworthy, caring, and smart. Briana does believe in second chances to the ones that actually want one and she is a very forgiving person, which tends to make her naive when it comes to trusting people that she shouldn't trust as she can easily fall for the manipulative of her enemies.

Briana also happens to see the world as "rainbows and cupcakes" despite the fact that she has everyone else trying to get her to see that's not how the world works. Although Briana has her own set of beliefs, her biggest belief is that she wants to change the world and make it so, mutants and those that are different from normal humans like herself can walk around in the daylight without having to worry about being judged, this is the main belief that she wants to do not just for herself but for those that she considers family and the rest of her loved ones.

Briana is known to hide the fact when she's angry when her biological father leaves the city to find something in Japan the day that he's free from Jake's spell, believing that he left because he wanted nothing to do with her as she blamed herself for him leaving. As time goes on and she learns more secrets, she will slowly but eventually learn to let go of this anger but as her journey continues, she will come across more things that she'll get angry at but with all that anger, sadness, grief, and pain she'll bury inside... when it explodes, it may or may not be good.

Briana also has a habit of giving her word as a way to promise something since she never turns her back on her word, always working hard to fulfill that promise she made as she sees it as her own ninja way.

Briana is also known to easily let her fear control her. When she finds out about her demon side, Unagami or the prophecy, Briana will try to avoid using her magic. However, when her magic first shows up, the first and only person she goes to about it is her adoptive father as she begs him for help against the voices and pain in her head. To which, Briana will follow her adoptive father's advice through everything and her whole life as the advice Master Splinter goes her is...

"Conceal it, don't feel it, don't let it show."

It's only a matter of time before that advice backfires on her as well as Briana will have to learn that the prophecy will happen whenever she wants it too or not.

Anxiety: Intense, excessive, and persistent worry and fear about everyday situations. Fast heart rate, rapid breathing, sweating, and feeling tired may occur [definition from Google].

None.

Any Pets?:
Briana does have a pet German Shepherd puppy that she named Max, who she adopted as her own when she found him abandoned in a alleyway alone, scared, and hungry. However, this soon changes after a certain incident that involves Max going through a transformation that will constantly put him and Briana on opposite sides.

Demon Abilities & Powers That Briana Can Do:
• Dark Demon Magic: This allows Briana to be able to conjure spells and use magic as a way to fight and protect herself. For example, she can make demon shadow hands with her magic.

• Super Speed: Briana is able to run faster than humans due to being the vessel of Unagami.

• Shadow Clone: This ability allows her to make one or two clones of herself. However, the clones will disappear if something happens to Briana since she is the host. When the clones disappear, the clone's memory will go to Briana since she is the host.

• Multi Shadow Clone: This ability is very similar to her Shadow Clone ability but this one allows her to make about two-hundred clones of herself. However, the clones will still disappear as well if something happens to Briana since she is the host. When the clones disappear, the clone's memory will go to Briana since she is the host.

• Telepathic Connection/Bond: Due to the fact that Briana is the vessel for Unagami and with Johnathon [OC owned @GeekyCookie1] being the vessel for Dread, the two of them have a telepathic connection/bond that allows them to feel each other's presence by sensing their magic. Due to this connection/bond, Briana and Johnathon [OC owned by @GeekyCookie1] can also speak to each other in their heads telepathically. Eventually, both Briana and Johnathon [OC owned by @GeekyCookie1] will discover that the two of them can feel each other's pain physically and emotionally.

Quotes:
[ongoing]

"No, Cameron [OC owned by @MariChat3] Kaz may a city boy as you call him but he's so much more than that. He's a man of nobility far greater than yours, a man who can make me happy, a man who can make me feel safe, and a man who can make me feel loved. So, I'm picking a man over a boy."

"Zane [OC owned by @MariChat3] you will see your dad again. Now that we know that he's alive and that Soren and Jake are hiding him somewhere in Shredder's lair, I promise you that I'll make sure you get reunited with your dad."

"I never turn my back on my word! That's my ninja way!"

"You found me."

"Pound it!"

"You were my new dream."

Other Facts:
[ongoing]

1. Briana is inspired by Emma Swan from the show Once Upon A Time, Elsa from Frozen and Frozen II, Maya Hart from Girl Meets World, Naruto Uzumaki from the Naruto anime, Wanda Maximoff from the Marvel Cinematic Universe, Hiccup Haddock from the How To Train Your Dragon series. She is mainly inspired by Rapunzel from Tangled, Tangled: Before Happily Ever, and Tangled: The Series.

2. Briana and Mara Sparks [OC owned by @MariChat3] have their own handshake, in which the two share a fist bump, calling out "Pound it!" after a successful mission. This is a reference to the show Miraculous Ladybug.

3. Briana tends to act all nervous and will stutter around Kaz, making it obvious to everyone [but herself and Kaz] that the two like each other more than friends. This is a reference to how Marinette acts around Adrien.

4. Due to being the vessel of Unagami, Briana has a hypermetabolism (also known as a fast metabolism) when it comes to food and because of her hypermetabolism, Briana cannot get drunk since alcohol doesn't affect her. This is a reference to Barry Allen from The Flash.

5. She was sent away as a newborn.

6. The relationship between Briana and Unagami is similar to the one that Bruce Banner has with The Hulk in the Marvel movie The Incredible Hulk. This relationship doesn't change till Briana manages to change that with Unagami.

7. Mutagen is a fatal weakness to her and can kill her within a few days if it gets into her bloodstream due to the fact that her demon magic and mutagen isn't compatible together.

8. Due to the fact that Briana was born prematurely before her due date, she is very scrawny and skinny.
