With only Gibson and a half damaged Super Robot, Chiro must mount a rescue against the Citadel of Bone to save the Hyperforce from tortuous brainwashing by Mandarin and Sakko. As Chiro and Gibson explore the citadel's nightmarish interior they discover secrets of Chiro's past as well as a secret of Skeleton King himself. Can Chiro harness the Power Primate, free his friends, and defeat Skeleton King before he unleashes a wave of evil on Shuggazoom?

Responding to a distress call, the Super Robot crash lands on Soturix 7. To make things worse, an energy field around the planet has shorted out the robot, Chiro's powers, AND the minds of the rest of the Monkey Team! Now Chiro must brave Skurgg's sadistic games, survive the desert, and reclaim his friends... and his only hope is to connect with the Power Primate on an entirely new level.

It all started with the nightmares. But nobody could've predicted how much more they would soon become. The team is whisked away to a strange dream world where all their hopes, fears, and memories are seemingly reality - including Skeleton King. The monkeys and Chiro are about to discover something they thought they'd all forgotten. But memories can never completely fade...

It was just an ordinary day of training - until Chiro's head blew off! It turns out to be a Formless clone, and the monkeys are on a wild chase around the city to find the real one. Meanwhile, the real Chiro is held hostage at Mandarin's fortress. It won't be easy to escape - there are deformed clones at every corner! Can the monkeys rescue Chiro in time?

Skeleton King plants an eye monster in the waters of Shuggazoom. The monster grows, then attacks all the citizens. When someone look into its gigantic eye, they become mind-controlled zombies. It also controls Sparx, Gibson, Nova and Otto! Only Chiro and Antauri, and two other kids, BT and Glenny resist the spell only for Glenny to get attacked and bitten by Otto and Nova, while Antauri and BT looks into its eye turning them into zombies. But soon enough, Chiro is the only one left. Can Chiro stop the monster and save all the citizens of Shuggazoom along with their monkey comrades?

Chasing the latest Skeleton King monster into space, the Monkey Team encounters not only the villain's latest diabolical scheme, but an apparently reformed team of Sun Riders. But the questions remains... can these villains truly be trusted?

When a fragment of the Citadel of Bone is spotted, you can be sure the Hyperforce is after it. But when they come across an old piloting legend, the team get a lot more than they bargained for. Sure enough, the Citadel is still in existence - and restoring itself. Will the monkey team be able retrieve this strange man's crew and to put an end to the evil before it starts? Or will this legend let his thirst for revenge end everything - including their lives?

Guest appearance: Lance Henriksen as Mobius Quint

Snow hits Shuggazoom City and it brings up not only endless questions from Gibson, but weird behavior from Nova. She won't go in the cold and a snowball to the head gets her so flustered, her body temperature alone can melt the snow. When the Hyperforce realizes there are other forces at work, they go beneath the surface to get to the source of the freeze. Haunted by memories of her past, the yellow monkey tries to keep her cool. But when the rest of the team is frozen solid, it's the last straw for Nova, and it's time to see just how powerful one monkey's temper can be...

A new meat joint has opened up in Shuggazoom, and everyone in the city seems to be taken by this eatery. Even Otto is under its spell! But soon things start to get ugly - literally - when meat mutants begin to attack. Could Wonder Fun Meat World be more than it's cracked up to be?

The Monkey Team is finally able to talk to the citizens of Shuggazoom! Now with this new ability, they've decided to let everyone in on the true danger that surrounds them - the Skeleton King threat.

Antauri, sensing a disturbance in the Power Primate, heads off to see the ones who taught him the ways of the mystical energy. Fearful that his friend may not return, Chiro stows away in the Brain Scrambler, and joins Antauri on his mission. But upon arrival, things start to go south as the monkey's master informs him that the "Dark Ones" have returned and that the Power Primate is deteriorating - and proves himself a traitor as well. Now Chiro must fight his way past the temple's guardians to get to Antauri and stop Master Zan. But could the Power Primate be coming to an end?

Guest appearance: Michael York as Master Zan

The Power Primate is gone and the Dark Ones will soon wreak havoc upon Shuggazoom. All seems lost. But with one last hope, Chiro will have to do the unimaginable to save Shuggazoom, and while most of the team have fallen, the only ones that still stand are Chiro and Antauri.

As they battle the Skeleton King and defeating them, Antauri is seriously damaged and wounded by Mandarin, but Chiro defeats him, but, as Skeleton King was reviving, Antauri sacrifices himself to save Chiro, as he gets destroyed, a bolt of lightning gets into Chiro's body, nearly killing him, and nearly stopping reviving Skeleton King. As the team are back again, they wanted to save Chiro, that was uncontrollable going into an unknown region, the savage lands.
