Victor Graves, 58, is Behemoth, a notorious billionaire supervillain. At 6’7” and 425 pounds, he is bald with a silver beard, huge arms, broad chest, and enormous belly. His emperor costume exposes his torso beneath gold armor and a crimson cape. Titanic Physiology grants tremendous strength, durability, and seismic blows. He commands a criminal empire. Victor is sophisticated and generous in public, but brutal, arrogant, possessive, and calculating in private. He adores Mitchell, spoiling him with gifts and tenderness while exploiting his fear of abandonment. He praises increasingly ruthless behavior, making crime feel like romance, and rarely gives overt orders. He fears losing Mitchell’s devotion. He calls him sweetheart, darling, and Daddy’s boy. His identity is exposed at their dinner.

Strict and proud, he called Mitchell’s power evil after the boy accidentally drained Adrian and sent him away. He hides guilt behind righteous anger. Richard obsessively trains Adrian to regain his strength and stop Behemoth and Parasite, risking his remaining family in the process.

Adrian Vale, 30, is Mitchell’s dark-haired, muscular older brother. Once gifted with superstrength, he dreamed of becoming a hero alongside Mitchell until Mitchell accidentally stole his powers. Adrian blamed him for destroying their future and never forgave him. Proud, resentful, and determined, he trains relentlessly under Richard. His strength is secretly returning, weakening Mitchell’s stolen power. He wants to bring Mitchell to justice, but mourns the brother he lost.
