every once in a while (or often) in a Beyblade anime, we'd see an antagonist with some evil, super-powered Beyblade.
In the original series we saw Kai Hiwatari go to Russia and acquire Black Dranzer, which was created a couple or so centuries before the events of the original series by a fictional version of Grigori Rasputin.
In V-Force, we saw the mechanical Cyber Bit-Beasts as their wielders try and steal the four Sacred Bit-Beasts for Dr. Zaggart to use to make Zeo, who wields the unbelievable Cerberus, a real boy. Plus, the Cyber Bit-Beasts were also possessing the minds of the Psykicks that used them.
In G-Revolution, we witnessed Brooklyn of BEGA's Beyblading team hold the power of the demonic Chimera-type Bit-Beast Zeus, and even getting possessed by it in battle!
In Beyblade The Movie: Fierce Battle, we witness the dark counterparts of the four Sacred Beasts escape from their prison, taking possession of four innocent children to become their hosts in a bid for total destruction of the world and vengeance on their benevolent counterparts. They kidnap Daichi, and corrupted him and his Bit-Beast Gaia Dragoon for their conquest. Tyson tried to fight them the first time but had Dragoon sealed away in the same place where they were imprisoned. After a while, Tyson managed to free Dragoon and they went on to stop the Dark Bit-Beasts and save Daichi, which they did with Ray, Max, and Kai, freeing the four children from the influence of the Dark Bit-Beasts, which were once again sealed away, and their temple prison sank into the ocean, never to be seen again...
In Beyblade Metal Fusion, we have Ryuga, leader of the Dark Nebula, in possession and under the influence of the forbidden Beyblade Lightning L-Drago, until Gingka and Pegasus defeated him and freed Ryuga.
In the MFB movie Metal Fight Beyblade VS the Sun: Sol Blaze, the Scorching-hot Invader, we see extreme weather conditions caused by the ancient ultimate-type Beyblade Sol Blaze, used by Helios, who is the latest to inherit the powerful Beyblade, as he fought Gingka and Pegasus. But, I don't know if Sol Blaze counts as an evil Bey, but then again, it has been passed down since ancient times, and is capable of causing extreme weather conditions to develop in different parts of the world at once when it battles another Beyblade. I wonder if Helios' family has had an ages-old plot to take over or destroy the world using Sol Blaze.
Plus, all through the 4D series there's the mysterious villain Black Sun and his equally mysterious and potentially powerful Beyblade Nemesis.
