Alexei Dinoia

Alexei Dinoia, is the antagonist from Tales of Vesperia of the Tales game series. He was the commandant (the highest-ranking officer) of the Imperial Knights. However, he was secretly maneuvering events throughout the story to his own ends. He was in fact behind most of the events. He desired to control of the Imperial Throne and world domination; however, his actions had accidentally brought about a threat to the entire world.

Alexei was mortally wounded by Yuri after releasing the Adephagos (an apocalypse-like force) at Zaude, before death he reflects that perhaps he "was the greatest fool of all" before he was crushed to death by the malfunctioning blasita core. Flynn later on have claimed Alexei's position after his death.
