Alexei Dinoia

Alexei Dinoia (アレクセイ ディノイア) is the primary antagonist of Tales of Vesperia. Alexei represents his country's government as the commandant of the Imperial Knights.

As an Imperial Knight
When Alexei was younger, he joined the knights in hopes that, much like Flynn and Yuri did, he would be able to gain enough influence to make the world a better place. As Alexei climbed in ranks, he became well known and revered for his ideals, gaining the respect and support of many of his fellow knights, including Schwann Oltorain, as well as the townspeople. In his spare time he researched vigorously for ways he could achieve his goals, and at some point, discovered the true nature of the Blastia as well as the nature the power of the royal family, and sought a way to use the information to help with his dream. However, as time wore on, Alexei grew more and more weary with the injustices of the world and he became more and more obsessed with changing things. Eventually, he began to believe that the only way to change things was to purge the world of its "scum", and decided that the only way to do so was to unleash calamity into the world. As he made his plans, he gained followers and continued his research. He also began to experiment with Blastia, one such experiment being the usage of Blastia to support the life of those who would otherwise be dead. During the Great War, Alexei would fit fallen soldiers with Blastia to replace their heart, and if successful, he would use the individuals to do his bidding. The two most notable successful subjects were Yeager and Schwann; the latter would eventually turn on Alexei and bring about his downfall. By the time of the events of the story, Alexei had become Commandant of the Imperial Knights and was prepared to execute his plans, with Khroma being his only fully informed confidant. His ambition took him to betraying the Knights and the government, but due to his promises of a changed world he had recruited many knights to his cause without them knowing the true nature of his plans. Flynn Scifo took his place after his death.

The Enduring Shrine of Zaude
At Zaude, the party finds Alexei in the deepest level, trying to figure out the formula to make it work. Alexei tries to escape to the top, but the party finally attacks and confronts him. Alexei is defeated, but while fightning the group, he was still analyzing Zaude. Alexei tries to activate it, only to be stopped by Yuri. Then, everyone witnesses the Adepaghos's arrival (in fact, the Shrine of Zaude wasn't a weapon like Alexei thought, but rather a barrier that the ancients used to seal away the Adepaghos, since they weren't able to destroy it ) and the death of Alexei, who was injured by Yuri and was crushed by the core of Zaude. Alexei had tears in his eyes before he died.

Fighting Style
As expected from the commandant of the Imperial Knights, Alexei is shown to be a formidable combatant and can be considered one of the hardest bosses in the game. He has an array of powerful melee attacks, such as Ill Wind, Apocalypse Toll (時練爆鐘), Guardian Frost, Radiant Dragon, Grave Worm (破邪地竜陣), and Raging Ice Fang. Alexei is also known to have very dangerous spells like Tidal Wave and Holy Rain. Alexei's most devastating attack is his mystic arte, Brilliant Cataclysm.
