Invincible: Blood of Two

Two sons. One world. No mercy.



Mark Grayson was born to be a hero.

Marcus Grayson was born to survive.



In a world protected by costumed champions and manipulated by secret powers, the twin sons of Nolan Grayson — Earth’s greatest hero — are raised in the same home, but shaped by very different truths.



While Mark dreams of flying and saving lives, Marcus watches. He listens. He prepares. Because deep down, he knows their father isn’t who he says he is — and when the truth comes crashing down, it’s Marcus who’s already ready to act.



As Mark rises as Invincible, Earth’s hopeful defender, Marcus walks the darker path. A brutal tactician,and the weight of secrets too dangerous to speak aloud. Armed with the knowledge of the future and a mind sharper than any blade, Marcus becomes the hero Earth never wanted… but may not survive without.



But blood is complicated.

And when Viltrum comes for them all, only one truth remains:



You can’t save the world… without spilling blood.
