Invincible.

A lean young male of average height with pale light skin, D.A. Sinclair has neck-length black hair slicked back, accentuating his noticeable widow's peak. His greyish-blue eyes are sharp and piercing, complemented by an Aquiline nose and a defined chin, giving him an air of authority and intellect. He typically wears a lab coat over casual clothing, with a pair of glasses perched on his nose, enhancing his scholarly appearance.

Sinclair is cold, calculating, and driven by a desire to prove his theories correct. He sees people as mere subjects for his experiments and has little regard for their well-being. His intelligence makes him manipulative, and he often uses charm to mask his darker intentions.

D.A. Sinclair is a brilliant but morally ambiguous scientist who believes that human weaknesses can be overcome through engineering. After attending Upstate University on a special program, he became obsessed with the idea of creating the perfect being, leading him to kidnap students and transform them into ReAnimen in his underground lab. His genius is matched only by his ruthlessness, as he seeks to push the boundaries of science at any cost.
