After a narrow victory against an eye creature, Antauri tells the monkeys to create new techniques by tomorrow. Chiro stumbles upon a monkey helmet and monkey glove which makes a shield.

Just as Chiro is beginning to understand the mysterious Power Primate, an enormous planetoid known as Q is detected headed straight toward the planet. Gibson's plan is to fly up in the Super Robot, and blast Q with Otto's newly completed gravaton disrupter. Simple, right? Not quite. Imagine the team's surprise when they discover that the giant planetoid is actually a living, speaking space creature! Their only hope is to be swallowed by Q, and disable the propulsion unit within it. Unfortunately for Chiro and the monkey team, this task won't be as easy to carry out as it sounds.

With the monkeys always beating the Formless before he does, Chiro is starting to feel a bit useless. After a failed attempt to catch the creatures before his teammates did, he discovers that the citizens of Shuggazoom City have mysteriously disappeared. And a trip inside a weird elevator with no buttons leaves Chiro imprisoned in a massive pit. But with the help of the Power Primate, he is able to call the team. They come to him rescue, only to be captured as well. Can the Hyperforce rescue the citizens of Shuggazoom from the Pit of Doom? Will they defeat Elevator Monster.

After saving a small abandoned creature from an avalanche of rocks on Shuggazoom's moon, Ranger 7, Chiro takes a liking to the little guy just like Chloe, much to Gibson's dismay, adopts it until they can find its true home planet. At first Chiro has a blast with Thingy, until weird things start happening. The Super Robot's functions go out of whack, even dumping Gibson into deep space.

To make matters worse, the virus has infected Gibson, transforming him into an evil mutant minion of the Skeleton King! Guest appearance: Frank Welker as Thingy

It's hot in Shuggazoom City. Very hot. So the monkeys decide to cool off with a swim, and everyone seems excited; except Sprx-77 and Chiro. But the water begins to rise, and soon floods the city. On a rescue mission, Chiro's fear holds him back once more, and no doubt would he have drowned if the team had not saved him at the last minute. Deciding to get to the source of the problem, they plunge down to the deep depths of Shuggazoom's water base, to find that the pillars holding everything up are terribly corroded. And the massive dents look oddly like teeth marks...

On patrol of the city, Sparx detects a strange force nearby. Chiro is eager to watch his favorite TV show The Sun Riders, so the magnet-fisted monkey insists that he go alone. He hasn't gone far when the other monkeys realize he's disappeared, and they can't contact him in any way. They set out to find him, and after a bumpy ride in the Super Robot, they find themselves stranded in a wasteland of junk, occupied by Lord Scrapperton, a man who has "upgraded" all of his human parts to make himself fully robot. But this guy seems way too happy - creepy happy - and Chiro is suspicious. He keeps the cybernetic collector busy while the monkeys search for their friend. Guest appearance: Eric Idle as Scrapperton

Chiro, who is tired of giving up his precious time to protect the city, suggests that an automatic defense system should be constructed to keep Shuggazoom City safe, so he doesn't have to. Otto and Gibson create the perfect line of defense, and it works magnificently after an attack by a weird [space] creature. But things start to get out of hand when three horrifying beasts slip through the cracks. The team successfully captures them, only to have them merge and go on a destruction spree! Now Chiro must take responsibility for relying on a machine to do the job that he was chosen to do, and stop Flytor with the team's help - even if it means shutting down their impressive defense grid for good.

When the team hits the circus for a day of food and fun, they get that and much more than they wanted. The mysterious ringmaster has taken an interest in the monkeys, and soon captures them with the help of the strange [Snake] Charmer and the enchanting [Jungle] Girl.

But can they free the rest of the team and stop these side show freaks from transforming all of Shuggazoom's citizens into creepy clowns? Guest appearance: Robert Englund as the Ringmaster

Can Chiro harness the Power Primate, free his friends, and defeat Skeleton King before he unleashes a wave of evil on Shuggazoom?

When Sparx says that Tolomac 3 is just another piece of rock floating in space, he couldn't be more wrong. It turns out that there's an entire kingdom of giants living there, and they've mistaken the Super Robot for one of their own.
