Bakugan Toys have become the hottest toys on the market. These little marbles are amazing. Based on the cartoon network cartoon, you can now battle your own Bakugan with the release of the toys. There are 6 primary colors in Bakugan. Luminoz is Grey, Subterra is Tan(Brown), Nova is Red, Aquos is Blue, Zephyroz is Green and Darkon is Black. You lay you metal Bakugan down and roll your Bakugan marbles that pop open in to characters. You then add the G rating on the marble to determine who wins the battle.
Now (around Nov 10th) Bakugan has just come out with the new Bakugan B2. They are a little bigger then the series 1 and series 2 marbles.
