Beyblade

Tyson faces off against Kane of Team Psykick and soon realizes his opponent has an unnatural advantage. Thanks to Doctor B, Kane has a powerful Cyber Bit Beast inside of his Blade. This means that when Tyson summons Dragoon, Kane's Cyber Bit Beast has the ability to copy Dragoon's moves and even improve on them. It's obvious from the get go that Kane's Cyber Bit Beast's powers are developing at an alarming rate and when it starts controlling his mind that's when things really get out of hand. Although a good Blader in his own right, under the control of the Cyber Bit Beast Kane's personality begins to change and when he's confronted by Salima he snaps and totally succumbs to its power. In the heat of battle and with the odds against him, Tyson reluctantly tells Dragoon to give in to defeat but the loyal Bit Beast summons the strength to continue the fight. This inspires Tyson and he vows to defeat the demented Kane at any cost.
