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 in disguise. 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 by 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 he will always be there. Shun is defeated by Shadow and passes out. The Vexos, having now captured the rest of the Resistance, plan to keep them as hostages while keeping Dan and the others stuck on Earth forever and while they take all Bakugan.
