Alan Sylvasta

In his human form, Alan has a fair complexion, blond hair, and teal eyes. He wears a dark teal suit, yellow waistcoat, a white collared shirt, and navy shoes.
As a normal beastman wolf, he appears to have light yellow-and-white fur and a humanoid looking face.
In his giant beastman form, he takes the form of a golden, three-headed wolf when he was powered-up.
Alan is a calm, poised, and commanding figure. When Yaba saw that Alan was calling him, he immediately tensed up and was fearful through the entire conversation. Alan's words also carry a lot of weight among his staff.

He also has a relaxed and playful side too. After the Medical Center bomb incident, he excitedly announces the closure of a research facility and his plans to visit Anima City.

He even has a certain pride as a purebred beastman, looking down on those of the hybrid bloodlines. Beneath his dashing exterior is a diabolical and manipulative heart that sought to control humans and beastmen at his own liking by pitching discrimination in both species.
He's the descendant of Reymond Sylvasta, a general who led an army that killed all the beastmen in the Eastern European beastmen-only city Nirvasyl roughly a thousand years before the events of the show.
Before the events of Anima-City, Barbara Rose (mayor of Anima City) trusted him, as she thought he was a "Good Human". Her research brought her closer to the Sylvasta corporation and, in turn, Alan Sylvasta himself. He was able to fool her into temporarily dismantling the city so that he would be able to carry out his plan.
Alan and Shirou share a mutual rivalry with each other, although Alan shows his disdain towards Shirou more passive-aggressively and insults the latter as a "hybrid". When fighting against Shirou in their godlike forms, Alan had no qualms to destroy Shirou.
He is the Main Anyagonist. In his god form he has 3 heads. Try to turn all beastmen into humans making them rage (Nyrvasil Syndrome)
