No you have to match your power to the numbers on the side then add together to see who wins the battle! Only match the colors with BakuNano's
Possibly Yes or at the same time maybe No. So it seems that if there will be a season 5 it will be called Tech Masters or something like that. I'm a Huge fan so hopefully... OK just watch out for new episodes do not trust that weird February stuff. Wrong there will be one its already released in japan and the bakugan toys are called bakunano
