In the english dub there were some misinformation. Kai was the leader of the Bladebreakers in the english dub only, not in the original dub.
Since there are always people editing pages with wrong information on the wiki, friendly reminder: Takao and Kai's last beyblades are Dragoon MSUV and Dranzer MS as pointed out in the chapter 14 of Bakuten Shoot when they are watching their sons (Makoto and Gou) confronting each other. Dragoon MF and Dranzer MF probably got destroyed in their last battle (since they don't own them anymore) in the previous chapter. The story of Rising happens after the chapter 13 and before the chapter 14 of Bakuten Shoot.
So, summing up...
DRAGOON: Dragoon MSUV -> Dragoon MF -> EVERY BEY RELEASED IN BURST (RISING) -> Dragoon MS UV (again)
DRANZER: Dranzer MS -> Dranzer MF -> EVERY BEY RELEASED IN BURST (RISING) -> Dranzer MS (again)
CHAPTER 13 and 14 END:
Tyson was intended to be left handed, this is also why his beyblades spin the other way. I'm leaving this note here. This was spoken to a bunch of people on a forum by a Japanese business man and fan back in the early 2000s, he was explaining why right handed people often have minor difficulties with Takao/Tyson's Beyblades. As far as I know its the only example of this from the early Beyblades, the rest were made for Right handed.
From what I gather, its because the way most launchers were designed only suited the right handed players, so Tyson's Beyblades were meant to cater to those who otherwise couldn't use the other Beyblades. Its sort of like a Left-handed scissor situation. One-Winged Hawk (talk) 10:48, January 17, 2018 (UTC)
Please don't be offended
The Pokémon comparison was sadly true and the fault lies with Hudson Software. The old Jisedai Begoma Battle Beyblade of where Tyson comes from was a clone of pokemon. The company also made Robopon, though they spiced up the main character by changing the style of hat (yet some assets are almost the same in the two games in terms of background stuff).
They were not the only company guilty of doing this... Medabots is also loosely based on Pokémon. There was also Space-Time Detective Genshi-Kun... which wasn't a game but was a manga and anime. One-Winged Hawk (talk) 21:16, January 18, 2018 (UTC)
