One day,
cards began to fall
from the sky and were picked up by kids all over the world. The cards
featured different characters (which could be reached by saying "field
open"), different environments, and different powers. Kids created a
popular battle game not knowing that these cards actually corresponded
to an alternate world called Vestroia.
In Vestroia,
a rogue Bakugan named Naga lusted for control, and schemed to seize all
of the power for himself. When he tried to absorb the silent core and
seize its power, the negative energy proved too much for Naga to
handle. The negative energy exploded and the Infinity Core fell to
earth. The creatures of Vestroia started to emerge in Bakugan battles.
Now it is up to Dan and the other Battle Brawlers to find the Infinity
Core and reunite it with the Silent Core to restore balance. At the
same time, an evil Bakugan player called Masquerade is taking away
Bakugan that belong to other people. As well, a scientist called
Michael Gehahbich disappeared into Vestroia. When he returned 6 months
later, he came back as a creature known as Hal-G, half Bakugan-half
human. Hal-G is plotting to reunite Naga with the Infinity Core to take
over the world. Dan and his friends must stop Hal-G's evil plans
