Bakugan
The spring-loaded battle-toy franchise from Spin Master and Sega Toys (Bakugan Battle Brawlers), tied to an anime series that launched in Japan in 2007 and on Cartoon Network in the U.S. in 2008. The toys were marble-like orbs that popped open into fierce little figures when rolled onto magnetic metal battle cards — a successor to the Pokémon and Beyblade collect-and-battle craze.
