Personality & Characteristics
He knows what he wants, and how to get it too. He thinks that if he can get the bit-beasts power (Dranzer, Driger, Draciel, and Dragoon) and transfer it into Zeo's circuits, he can turn Zeo into a real boy. He convinces Zeo that he can be turned into a real boy by talking Zeo into his crazy plan, and all he has to do is leave Tyson and the Bladebreakers, and steal their Bit-Beasts.
His eldest son, Zeo, died in an accident many years ago. Overcome with grief, he forced his youngest son to assume the identity of his older brother and to change his name from Leon to ZO. In the anime, ZO is an android that Dr. Zagart created to replace his deceased son.
He began the project to extract the bit beasts from the ancient rock. He first hired Alan McKenzie to steal the ancient rock from Judy's lab in NYC. He then proceeds to have Doctor K have the bit-beasts captured but after several failures, he fires her.
He extracts two extraordinary bit-beasts from the rock, Orthros & Cerberus which he then sealed in the two coinciding blades (Orthros & Burning Cerberus). He then chose an expert blader named Gordo to wield Orthros and train Zeo, his android son copy to perfection. He then gave Burning Cerberus to Zeo. He had them both enter the world championships.
Thanks to Zeo, he managed to collect Dranzer & Draciel but due to Tyson & Dragoon, they were both freed ensuring that Zagart plans to make Zeo human are foiled. He then accepts Zeo for who he was & the two live on better terms with the world.
Leon is Dr. Zagart's younger son, whom he trained to be like Zeo after Zeo's death. In the anime, he is actually an android replica of the real Zeo.
Zeo is Dr. Zagart's first son, who was killed in an unfortunate accident.
Mr. Dickenson and Dr. Zagart were once colleagues known for doing bit-beast research. After going their separate ways, their friendship was strained, though it's implied they made amends after Dr. Zagart reformed when Tyson defeated his son in battle.
- Dr. Zagart is the only main antagonist who reformed after his defeat.
