Changes

The reissued older releases of the BakuTech series bear the suffix of {{Nihongo|'''Kai'''|改|kai}} after their names. Kai is from the Japanese verb meaning "modify" or the noun meaning "reformation." As the suffix suggests, each of the Kai releases have a different color palette from the original releases. More importantly, each of them has some of the plastic non-Convert Parts, usually located at the lower part of the Bakugan, changed into metal, which lowers the center of gravity of and gives extra weight to the Bakugan, consequently increasing its defensive power. However, the change of the center of gravity may make the Bakugan only suitable for curve shoot with its Convert Parts unchanged.
