Dan and Drago enter the hybrid world of Pyrus and Darkus where the dark army is running rampant. Dan and Drago are saved from Pyrus/Darkus hybrid Bakugans Centorrior and Druman by Nobilion: a Pyrus Tigrerra who is the oldest and wisest of all Bakugan. Nobilion explains how the negative energy has been influencing all of Vestroia, except those who can hide. Nobilion also mentioned that the Negative Energy has also created the evil hybrid Bakugan. Upon running into Centorrior and Druman again, Drago and Nobilion end up engaging them in battle. With Nobilion's sacrifice, Dan and Drago try to defeat Centorrior and Druman.
