Rock Leone is the first bey Kyoya owns. He first used it against the battle with Gingka, after defeating the Face Hunters. Gingka pretty much just got worried at the first fight, but that didn't worry him enough, so he stomped him with Starblast Attack, making Rock Leone play itself. In the second battle, Rock Leone beat the shiz out of Storm Pegasus, until it did an asspull and defeat leone. Rock Leone seems to be WAY stronger in Metal Masters, being able to fight Galaxy Pegasus and have an advantage over it. Until they beat the shit out of themselves and it ends up in a tie. Same as Metal Fury, except the collision of special moves didn't beat the shit out of their spinning. After metal masters, this Bey wasn't used ever again in any major fights.
