BEGA rises
When the championship finished Kate still kept in Japan and she passed the most part of her time at Tyson's. Everything was going peacefully well until the BBA got suddenly closed one day and BEGA appeared on its place. Kate was in totally despair and disbelief when she saw that the owner of BEGA was Boris and that his chief was still Voltaire. As they tried to convince her, Tyson, Max, Kenny and Daichi that they were different from before Kate couldn't believe in a word they said. She also didn't her friends be caught by that same old promises of power.
Kate was already worried but it got worse when Tala and the other Blitzkrieg Boys, except Kai, said to her and to her friends that they were going to stop Boris' and Voltaire's new plan before it was too late. She tried to go with them but Tala didn't let her go, since challenging Boris could be too dangerous. However after some time she and her friends decided to go to BEGA anyway and they arrived there just in time to see Bryan and Spencer being defeated by the cruel and arrogant Serena, but it had not ended yet because Tala was about to begin a fight against Garland. Kate was with a real bad feeling and it was confirmed when Boris obligated the two bladers to fight until exhaustion and so Tala got severely hurt.
Kate was crying of despair, begging to her brother to talk to her. He only said that he discovered that Barthez was an ally of Boris and that he just took the Majestics from the championship because they wanted to be the world champions in order to satisfy Voltaire's plans. After that, he went unconscious and Max and Spencer helped Kate to take him to the hospital, but there the medic said that the boy was in a coma.
Kate was already destroyed but there was more: Kai betrayed her once again when he decided to join BEGA. Moreover, he betrayed Tala and all the other abbey boys even knowing through what they passed in Boris' hands. He didn't even care about the fact that Tala was at the hospital. Nobody could believe that Kai was being so cruel just to face Tyson again. And he was not the only one who betrayed them, Hiro also did it.
Tyson was so mad with that entire story that he challenged BEGA for a match, but the new team G-Revolutions needed to reconstruct their beyblades in order to have a chance to defeat them. They and the remaining Blitzkrieg Boys, who stayed with them at Tyson's too, tried several times to buy beyblade pieces, without success. At least the former Bladebreakers were positively surprised on how the Russians were friendly outside a stadium.
Everybody was still depressed about Kai's betrayal and Kate along with the Blitzkrieg Boys visited Tala at the hospital every day. It was a dark time for her heart again.
