Personality & Characteristics
Boris seems to bring either fear or hatred from anybody who knew him at one point of history. For instance, while Kai, Tala, Spencer, Bryan and Ian display much loathing towards the man, younger kids such as Alexander are frightened by him and do anything he orders them to do.
In the first season, he was the Demolition Boys' trainer and also the main authority in the Abbey, but secretly given orders from Voltaire. Boris was the one who selected the boys he thought would fit in the monastery to train them to become excellent beybladers who would be part of his army to gain more power.
After the failure of his plans to take over the world, he came back, in G-Revolution, with an organization called BEGA. His goal was to transform Beyblade into a professional sport because, as he said, he was a changed man after he had wandered in Russia and watched kids play Beyblade in the street, telling Tyson and the others that he has turned a "new leaf". Of course, this sounded bizarre to everyone, and, no matter how much he cried while explaining his story, people like the Blitzkrieg Boys knew BEGA was in fact only a way to get more control, again.
Boris was also behind the whole Barthez's Soldiers scandal as he was probably the one who recruited Barthez in the first place as a mean to win his way through the Championship by cheating. When BBA Revolution faced Barthez, Miguel and the rest of Barthez team turned on Barthez, Boris' plans were failed.
During the qualification rounds of BEGA, he was uncaring as to how the match between Brooklyn and Kai played out, as long as the winner was the one he had in mind: Brooklyn. Boris told Hiro that he wanted the battle to be quickly over, and did not even raise an eyebrow at the damage Brooklyn was inflicting at Kai.
When BEGA fell, Boris was run over by dozens of fans who were going to see Tyson and Brooklyn battle. He was also peed on by a dog and a bird defecated on his face, but only in the Japanese version. Hiro Granger exposed his true reasons for joining BEGA and resigned from his position there as coach.
In the manga, Boris was actually only a subordinate to Dr. Zagart, and both worked to learn more about sacred Bit-Beasts so Dr. Zagart could steal them and resuscitate his first son Zeo.
Boris was also related to the Saint Shields, since they temporarily worked for the two men regarding the sacred Bit-Beasts matter.
- In Russian, Boris' name is spelled Борис Балков.
