No, we have plenty of tournaments that do not require Takara Tomy Beyblades, though you will not be able to participate in official tournaments.
No it didn't. Beyblade is alive, well and very cool as it has always been.
While Hasbro Beys are generally easier to get and sometimes cheaper to get in America, Takara Tomy Beys almost always outperform Hasbro Beyblades because of the way the burst system works on Takara Tomy Beys and overall build quality. On Takara Tomy Beyblades, the Beys are held together using the tooth system as opposed to the slope system that Hasbro Beys use. The tooth system is way stronger as opposed to the slope system, which simply holds the beyblades using an incline and no teeth, which make them easier to burst, thus making the competition heavily skewed toward the Takara Tomy user. Furthermore, the materials on a Takara Tomy Beyblade are actually made to the specifications the bey is supposed to follow. With Turbo Hasbro beys, the metal on the energy layer is replaced with plastic, making it infinitely worse than it's Takara Tomy counterparts. Luckily, Hasbro has released the Pro Series, which are more faithful to their TT counterparts. These beys are allowed in UBS tournaments.

While the UBS doesn't have nearly as much funding, the UBS has a better sense of community, along with a rich history. For info about the history of the UBS, go to the about us page.
