RYUGA (part 3)

Personality
Ryuga's personality varied greatly between seasons. This is most likely due to him getting rid of the dark power, that effected his personality.

Beyblade: Metal Fusion
In Metal Fusion, Ryuga was portrayed to be evil and merciless to his few allies and enemies. He loved to attack the Beys of his enemies until the Bey was defeated. He also enjoyed terrorizing other Beybladers and had a power-hungry personality; he despised losing a battle as well. He was cocky, thinking that he had the power to beat anyone else before him. In the finale, Blader's Spirit, it was revealed that Ryuga's actions was caused by Lightning L-Drago's possession over him.
Also, after being freed from the dark power, Ryuga obtained powerful knowledge about becoming one with a Beyblade and understanding it, in contrast to his power-hungry personality from before


Beyblade: Metal Master
Ryuga he is more of an anti-hero now, instead of a villain. He was also a mentor for Tsubasa during the season, to help him as he struggled with his dark power.
Ryuga did not seem to be very fond of Julian Konzern and his Beyblade, and Gravity Destroyer AD145WD because Ryuga believed that there should be only one reverse-rotating Bey, which is his L-Drago.
Ryuga did help Team Gan Gan Galaxy because had subbed in for Tsubasa and Yu while they were in the hospital.

Beyblade: Metal Fury

However, he still retained a lust for power in Metal Fury, as shown by his repeated attempts to control or absorb Nemesis's power, although he was not as hungry for power as before.
In Kenta's Determination, however, he was shown to be caring. He took care of his Bey, waited for Kenta under a tree when he fainted, used L-Drago to light a fire for him, and even fed him. He was also shown to have a "sixth sense" which makes him alert to Beys being prepared for launching, to which he quickly launches his bey to either stop the Blader or ignite a battle.
While battling Rago in the Beggining of the battle Ryuga Use his special move Dragon emporer Decends Which didn't really have effect on Diablo Nemesis. Ryuga new he had no chance of defeating Rago he ended up being flown back almost dead but helping Kenta during the battle with Rago.
