Masefield, Brooklyn

ブルックリン

Brooklyn is the strongest competitor in the series that Kai and Tyson must face. He is a naturally gifted Beyblader who does not need to exert effort to win. His personality has two sides: first, a calm and seemingly gentle side, and second, a psychotic, aggressive side. He defeated Kai as easily as child's play in their first match, although he lost drastically in their second when Kai, as he himself stated, unleashed his "true" potential. He has always believed that no one can beat him, so he did not put any hard work into battling because of his "natural ability".
Like Tyson, he is at one with his bit beast, but Brooklyn forms physical traits of his bit beast; for instance, wings form on his back that reflect his bit beast Zeus's wings.
His childhood strongly influenced his personality. Because he always won, other children did not want to play with him, so he was often left alone. During Brooklyn's Beyblade match with Tyson, because Kai defeated him, he went insane. Brooklyn has always Beybladed using only his natural ability, and because that was good enough to win, he never put much energy into his matches. He realizes that by using the combined powers of his emotions and abilities, he could create much more damage. Eventually, all his negative emotions reach their apex, especially his annoyance, frustration, and sadness. These mix with the evil darkness of his demonic bit-beast, Zeus, and using the King of Darkness attack, creates a black hole that proceeds to ravage and devour the entire world and everyone in it into his soul. Thus, he declares himself a god. He only calms down once Tyson explains to him the true meaning of Beyblading, using the power of the bit-beasts of his team-mates (Kai, Ray, Max, and Daichi) and Tala's Wolborg (Tala woke up from his coma and sent Wolborg with his special ice attack to help Tyson) to dispel Zeus's darkness, returning the world to normal, albeit heavily ravaged. Once the chaos had passed, Tyson and Brooklyn continue their battle as it should have been, a friendly competition, free from the machinations of the now disgraced Boris. Tyson wins in the end due to Dragoon absorbing other bit-beasts's powers and then attacking and defeating Zeus. Both bladers then took their Beyblades and battled again, however, the victor was never actually shown.
