Eight Unabara

Eight is the younger sibling to his older brother, Kite Unabara. Both take a liking to the element of water, and own Beyblades of a water element. Eight can be strong in battle, but can also be a sore loser, and a "cry-baby" about it. He likes to draw on the face of his opponents when they lose with a pen, in order to humiliate them a bit more and to have fun. (Source: Beyblade Wikia)
