The Hero of the series. Quite an Idiot Hero at that, too. He's got nothing more than a decent top and a love for the game, but that changes when he finds the bit-beast Dragoon in his grandfather's dojo. He joins with Ray, Kai, and Max and wins the world championship for all three years of the show.
Aesop Amnesia: Especially in the later two seasons, where he is in constant need of getting his ego put in check.
Glory Seeker: Very much so, to the point that he unnecessarily takes away challenges that could have been spread around the group to make for more interesting rivalries. While in Europe, Tyson gets to battle Robert, Oliver, and Enrique, three of the best bladers on the continent, while Johnny is saved for Kai. Tyson gets three rivalries, while Max and Ray get what?
It's All About Me: For the first half of G Revolution, Tyson has this attitude. He refuses to understand it's not Ray, Max, and Kai's responsibility to get him to the finals of every tournament, only for him to take the title in the end, and then think "they" are champions, when Tyson is the one who gets all the glory in the end.
Living MacGuffin: It seems like everyone one wants a piece of him, and/or his bit beast.
Small Name, Big Ego: To be fair, it's partly justified. Tyson's become the world champion two times in a row. However he tends to think he's unstoppable and lashes out at people when things don't go his way.
Took a Level in Jerkass: While his team mates mostly mellowed out following their initial arcs, Tyson's selfishness and ego problems snapped back and worsened with each season, only causing spaced issues in the first.
The Lancer to Tyson. He was actually the team captain of the Bladebreakers, and was almost always shrouded in mystery. This changed when the team went over to Russia, where a bit more was divulged about his past. He made a brief Heel-Face Turn to join the Demolition Boys, but decided to return back to the Bladebreakers after they proved he belonged with them. In the third season, he defected back to the Demolition Boys (now known as the Blitzkrieg Boys) so he could face Tyson in the world championship. He does, and he loses.
Knight Templar Big Brother: Someone better help you if you do anything to his friends! He WILL hunt you down, and GET his revenge. Just ask him about Wyatt.
Characterization Marches On: Hugely apparent in V Force. Kai's more willing to talk to people, gives helpful advice as a team leader, and is visibly closer to people. All while still being stoic and standoffish.
Dull Eyes of Unhappiness: After being defeated by Brooklyn he is seen aimlessly walking around and slouched on the ground of an alley with these. The look is completed by the tired lines underneath his eyes.
"The Reason You Suck" Speech: Kai gives an epic one to Brooklyn, explaining that despite being the most powerful beyblader in the series, it doesn't mean shit because Brooklyn has never once put his heart and soul into the game from beginning to end like Kai has. It pretty much traumatizes Brooklyn too.
The Big Guy: Most passionate and brutal competitor of the bladebreakers.
Characterization Marches On: Similar to Max, Rei started off slightly more comical and shared some of Takao's arrogance and playfulness. This faded in favor of him becoming a more lucid Team Dad for the others.
Chick Magnet: Very much in season 1 though this quickly dies down after.
Took A Level Of Jerkass: Slowly turns from the nice and easy-going from season 1 to more angry and demanding by season 3. Possibly because he had inner longings to have a rematch with Tyson (he forfeited in season 1, and did not have any chances to battle him in tournaments after) and the pressures of being the new captain of the White Tigers. After his rematch with Tyson, he does get better.
Curb-Stomp Battle: She not only knocked Draciel out of the match, she blasted him out of the stadium so hard, Max couldn't even react to catch his blade!
Humble Pie: She never fight against Max again but the exhibition match before the American tournament (in which she, Max and a lucky normal blader were teamed together) knocked her down a peg since, even if you have good strength. It doesn't mean jack squat if your opponents gang up on you. Heck it was Max's strategy that wound up winning them the match much to her chagrin.
Insufferable Genius: Emily's smart and she knows it. And won't let anyone else forget it either. Course smart doesn't mean automatically better
Berserk Button: While Enrique much prefers to enjoy the company of his girlfriends and spoil them rotten rather than live up to his title as the best blader in Italy, he does not take well to anyone assuming he's a poser who has no real skill, as Tyson soon found out.
Half-Identical Twins: It's a bit difficult believing that Queen and King are even related at all, let alone twins.
Hoistby His Own Petard: Used an attack that ended up destroying her own blade, which after so many times she had done the same to other bladers very karmic. indeed.
Karma Houdini: It could be argued that she and her brother are actually the most successful villains in the show. They got away with all their crimes technically speaking. Queen had her blade and bit beast destroyed thanks to her attack ring backfiring on her, now that's karmic punishment.
Brilliant but Lazy: He'd rather sit in a grassy field and play with small animals than watch a beybattle. But he's the most naturally gifted blader in the series, he doesn't ever need to practice anyhow. His immense natural skill even gives him some sort of unexplained powers of prescience that allow him to predict most outcomes of battles.
Mix-and-Match Creatures: Zeus is an odd mish-mash of many animals. According to the Beyblade wiki, it has "the head, fur and arms of a jungle cat, a white lion's mane, black eagle-like wings, a horse's lower half and bull horns growing out of his chest".
Adaptation Distillation: Appeared much more earlier in the manga and also wielded Metal Draciel and Metal Dranzer instead of just Metal Driger.
Char Clone: Besides hiding his identity at the beginning, he seems somewhat amoral, as if all it mattered to him is seeing Tyson getting stronger like when he fake defected to BEGA. And towards the end of the show he is dressed almost exactly like Char in Zeta Gundam, except the colors are different.
Chessmaster: His strategy of improving Tyson's beyblading. He joined BEGA so Tyson would step up his game considering the opponents he is facing. He personally trained Brooklyn, getting him interested into the sport and possibly getting better through Kai (he may have wanted Kai to face Brooklyn twice because he will know that he will lose at first but come back stronger and beat Brooklyn. After all, Hiro approved Kai's request to challenge Brooklyn. He knew that Brooklyn will be deeply affected by the lost and become stronger, giving Tyson a really tough challenge later on. One must wonder how deep in the tournament did he plan.
