With Ace and Marucho captured by the Vexos, Shun decides to head to Beta City alone to destroy the controller. On the way, he is ambushed by Shadow Probe, who is armed with Darkus Hydranoid. In the middle of the battle, Shun and Ingram realize that it is not the same Hydranoid they know, it is really mechanical bakugan Darkus Hades. Darkus Hades was created from Hydranoid's DNA and has none of the weaknesses that Altair had. Shun tries his best to hold his ground but Ingram and Hylash are no match for Hades and Bakugan Trap Darkus Fortress. Shun contemplates throwing in the towel out of fear for losing his partner like how he almost lost Skyress in a tough battle, but Ingram convinces him otherwise and that she will always be there next to him.
