The Bakugan™ Battle Brawlers
promotion ran for four weeks. The set consisted of two characters
Preyas™
and Hydranoid™
and each character had his own Battle Balls which were
available in four different colours. Each ball transforms into a
battle piece:
Preyas Balls
Hydranoid Balls
Each piece also included a
Bakugan Battle Card
and there were 12 different cards available.
