Character Synopsis:
Fabian "Flash" Kisho Sentry had always seen himself as a monster.

The reason for that lead all the way back to his father, who had done nothing but abused him and his brother into the little soldiers that they were. His whole life, Flash Sentry has grown up learning the ways how to kill and fight without mercy, how to take orders without hesitation, and how to "be a man" in the words of his father.

It's why he's always seen himself as a monster, so afraid of himself that he once didn't planned to have children since he was too afraid that he'd ruin them just like his father ruined him.

It's why he always thought that he was meant to be alone for the rest of his life.

It's why he was so terrified of knowing that deep down, there was a chance where he was just like his father and that was his fear.

But it's funny how Princess Theodora "Twilight" Sparkle manages to change his mind after the two first met. Although their love story wasn't easy, it was one that was clearly fought for and they won.

Then, the two happily had two daughters but their family became even more complete when five mutant turtles and their goddaughter joined the family.

Relationships with his family:
Kenji Sentry - biological abusive father. Flash Sentry has never been close with his father due to Kenji's value over strength or because of his father's abuse as Kenji claims that his son is weak and pathetic.

However, Kenji's abuse affected him the most since due to that reason, Flash Sentry has trust issues so if he gets a wrong vibe from someone, he will not trust that person, he views himself as a monster because of all the blood that's on his hands, and because of how deep down, Flash Sentry secretly just wanted Kenji to be his father.

Akira Wilson-Sentry - biological mother. Flash Sentry shares a complicated relationship with his mother. Although Flash Sentry adored his mother as a child as he is saddened by her death. But upon learning that his mother faked her death in order to leave, he grows resentment towards her for abandoning her two sons with their "monster of a father" and holds a grudge against her, refusing to forgive her for her actions.

However, the motherly-son bond is even more shattered when Akira Wilson-Sentry manages to kill Briana to keep Davina away from the Crystal Empire. Of course, it doesn't work out the way that Akira wants since Davina still shows up to kill them all. Although Flash Sentry hadn't forgave his mother for abandoning him and his brother, he is shown a true glimpse of his mother's love when she sacrificed her life to save her children.

Emiko Sylvie Sentry - biological eldest sister. This relationship starts out rocky as Flash Sentry mistrusted her from the moment that he first met her, even after Emiko proved that what she was saying was true, as he refuses to see her as his sister. However, it isn't till Davina's death that Flash Sentry where he finally accepts Emiko as his sister after everything they've been through and the two of them finally start becoming close.

Quill Teiji Sentry - biological eldest brother. Flash Sentry shares a very close bond since they only had each other throughout the years that were spent with their abusive father.

Queen Theodora "Twilight" Sparkle - current wife. Upon first meeting her, Flash Sentry did his best to avoid his feelings for her at first in fear of turning out like his father. However, due to almost losing her a few times because of his father, Flash Sentry gave in to his feelings that led to the two getting together and eventually married where they had their own family.

Princess Briana Gem Sentry - biological eldest daughter. Due to not being there throughout her entire life and for sending her away to keep her safe, their relationship starts out as awkward at first as neither one of them knows what to do [with Flash Sentry not sure of what to do while Briana struggles to accept her new life as a princess]. But eventually, the two grow a close father-daughter bond.

Princess Diana Leia Sentry - biological youngest daughter. Having been there for her up till she was one-year-old [having been when her father got captured by the Foot Clan in order to protect his family and the kingdom while her mother cast the spell that created the mysterious fog around the kingdom], Flash Sentry and Diana's fatherly-daughter relationship is very close and remains that way even when the two are reunited since Diana got what Briana never had; both of their parents in her life.

Karai/Miwa Hamato - goddaughter/adoptive daughter. As his and his wife's goddaughter, the two soon share a natural father-daughter bond—one that Karai/Miwa Hamato never got to experience with Hamato Yoshi/Master Splinter since she had been too focused on her revenge at the time.

Leonardo "Leo" Hamato - adoptive son. When he and his wife take him in as their son and even before then, the two develop a father-son bond.

Raphael "Raph" Hamato - adoptive son. When he and his wife take him in as their son and even before then, the two develop a father-son bond.

Donatello "Donnie" Hamato - adoptive son. When he and his wife take him in as their son and even before then, the two develop a father-son bond.

Michelangelo "Mikey" Hamato - adoptive son. When he and his wife take in him as their son and even before then, the two develop a father-son bond.

Eclipse "Clips" Hamato [OC owned by GeekyCookie1] - adoptive daughter. When he and his wife take her in as their daughter and even before then, the two develop a father-daughter bond.

Physical Appearance:
While he is an attractive man, Flash Sentry has curled blue hair and blue eyes. Due to his childhood and martial arts training, he has a very athletic body that he keeps in shape. His clothing style is a white shirt, black leather jacket, black jeans, and black sneakers with white laces on them.

Personality:
Due to his childhood and his father's abuse, Flash Sentry has trust issues and can be a little paranoid, hence the reason why he refuses to accept Emiko as his sister upon first meeting her. He is known to be overprotective of his loved ones and due to his fear of becoming his father, he hides how he feel inside as he is afraid of being seen as weak and pathetic—as Kenji Sentry had often called him that throughout his entire life, hence a trait that he realizes Briana got from him as the two often hide how they truly feel deep down beneath their walls.

Flash Sentry also has a temper, one that he got from his father.

However, Flash Sentry is also quite loving, caring, kindhearted, intelligent, creative [as he enjoys painting to get his mind off of things that bother him], and extremely stubborn. Although there are a few times where he tends to let his insecurities get the better of him, another trait he realizes that Briana got from him.

Quotes:
[ongoing].

"Mark my words. If you come after my family, I will rip you apart. And I get my temper from my father." — Flash Sentry in general, but mainly directed towards Soren Chandler [OC owned by MariChat3].

"Attempt to kill us all and you'll be making a mistake, Soren. And besides, even if you did managed to eliminate us all, one day my children and the rest of their family would come for you, and their children after that. On and on for all your days. An endless cycle of violence is what you will bring upon yourself and your son." — Flash Sentry to Soren Chandler [OC owned by MariChat3].

"Seems like we're officially orphans." — Flash Sentry to his siblings after their mother sacrificed her life to kill Davina in order to save them.

"Family isn't just the people who coddle you, who grant you your every wish. They are the people who fight for you, who you fight for." — Flash Sentry in general.

"Family can be more than just those with whom we share blood. We can choose our family." — Flash Sentry in general.

"You abandoned Quill and me! You left us with our monster of a father! Well, guess what? You rant and rave about the monster I have become, but you, Mother—you and father are the author of everything I am." — Flash Sentry to his mother, Akira Wilson-Sentry.

"We were innocent once, brother. The way that we were raised was forced upon us by our father—he turned us from the children we once were to the killers we are now. We are the demons lurking in the shadows, we are the savage killers in fairytales told to children but not for my children. Not for Miwa, Briana, Diana, Leonardo, Raphael, Donatello, Michelangelo, and Eclipse. In their story, we are the knights in shining armor. Without you or Twilight by my side, I don't think I can survive my own love for my children. I need you. I need you, brother. The monster in me can only be checked by the monster in you. Only together can we defeat our demons and save our family." — Flash Sentry to his brother, Quill Teiji Sentry.

"No, Quill and I weren't born like this. Her you fight for; lovely Emiko, the daughter you barely know. But there was a time when you knew me and Quill as your sons! There were moments where all you had to do was to be our father! And even then, you despised us, didn't you? I want to know why." — Flash Sentry to his father, Kenji Sentry right before he kills him.

"Oh, come on, Quill! You can't honestly say you're surprised, can you? You wanted Davina dead just as much as we all do, I wanted to punish our mother, and I had a way to kill two birds with one stone! I am never going to change, our mother is never going to change, and you are never going to change! You're never gonna stop straining to find one tiny speck of redemption in our mother, and she's never gonna stop disappointing you [Quill finishes talking]. I don't want to know the whole story, Quill! I don't want to know any more excuses or lies or anything that tells me anything other than the way I know it went down. Our mother faked her death, left her sons behind, searched for her daughter nonstop, and went out of her way to forget us forever! That is the only story that matters, Quill. She tossed us aside without any concern what would happen to us or what father would do to us. As far as I'm concerned, our mother deserves what she gets. She deserves what she gets." — Flash Sentry to his brother, Quill Teiji Sentry about their mother, Akira Wilson-Sentry.
