Bakugan

Bakugan Battle Brawlers. "My whole life changed one day when these random cards were raining down everywhere. At first they seemed harmless enough so a bunch of us kids created a cool new game, that's when we realized these cards weren't so harmless after all. They were packed with incredible powers from another world." The Bakugan Battle Brawlers: Dan Kuso: The leader, Pyrus attribute user, partner Bakugan is Dragonoid which he calls Drago. Runo Misaki: The hot headed tomboy, Haos attribute user, partner Bakugan is Tigrerra. Marucho Marukura: The rich one who is also the tech guy, Aquos attribute user, partner Bakugan is Preyas. Julie Makimoto: Not much to say about her then she's honestly annoying, Subterra Bakugan user, partner Bakugan is Gorem. Shun Kazami: The calm one and a ninja, childhood friends with Dan and created the game alongside him, Ventus attribute user, partner Bakugan is Skyress. Alice Gehabich: The kind hearted strategist from Russia, dislikes brawling and doesn't have a partner Bakugan but knows pretty much everything about Bakugan. The villains: Naga: The main villain who tried to control all the power in Vestroia but in doing so accidentally imprisoned himself inside the silent core. Has the power of brainwashing. Hal-G/ Dr. Micheal: Alice's grandfather who discovered the Bakugan and when Naga seized the silent core he was infected by Naga's negative energy which turned him into Hal-G and under the control of Naga. Masquerade: A masked figure who wants the ultimate Bakugan and is working for Naga for unknown reasons, basically being Naga and Hal-G's enforcer, Darkus attribute user, partner Bakugan was Reaper but he replaced it with Hydranoid seeing more potential in it. Sends Bakugan to the doom dimension. Top ranked brawler in the world, getting the title seemingly over night. There are other characters like the top ten ranked brawlers and Wyvern who is Naga's sister and Drago's girlfriend but there isn't enough room to explain them all.
