Summary
Hero. There aren't many who can give you the same opinion of what a hero is... everyone has their own definition. But everyone can collectively agree that a hero saves lives and beats the bad guys.
The GDA creates a boy who can become that hero. Yet as the challenges wage on as the boy fights threats alongside other heroes, he will soon learn there's much more than just fighting threats.
Being seen as an abomination, nothing but an emotionless shell of his original, he tries his hardest to save.... because that's what a hero does, he saves lives, and he doesn't stop.

Summary
"So...you named yourself Invincible, yet you've had your ass thoroughly beat on more than one occasion?"
Mark huffed softly at the inquisitive tone of the other boy, a light flare of embarrassment--maybe even amusement--dusting his cheeks as he leaned back on his palms; the rough texture of cement a dull pressure to the pads of his fingers where they protruded from his gloves. The two were sat upon one of the many skyscrapers in the city, a brief respite from fighting crime for the past hour or two.
"I- well, I thought it was a good name at the time! And it sounds cool," he argued, head tilting to look every other way than Casey, the dim shine of the setting sun glinting off his mask's goggles. Lifting his arms, Mark crossed the limbs over his lean chest, the movement smudging a bit of dirt that had rooted itself in the blue stripe that curved beneath the chest of his suit.
Casey only managed a small head tilt at Mark's tone, a hint of defense bleeding through. It made the boy's lips curve slightly. "Well, least it's easy to pronounce--can't say the same for mine."
---
Or, a story in which Cecil ends up finding a use for Mark's blood after all--an asset at his complete beck and call.

Summary
Camille “Cam” Grayson is the oldest daughter to Debbie and Nolan Grayson. Just like her brother, Mark Grayson, she grew up relatively normal. As normal as can be when your father is the most powerful man in the world. the idea that she could follow in his footsteps was held over her head since she had been told about her father origins. Though, years later she was now just a history major at Upstate University. Completely average.
