Return to Imperium

After a mysterious event known as "The Merge" shuffles the universe, an aspiring Ninja teams with a smart techie to navigate a new and unfamiliar world.

The Merge (1)

Arin and Sora develop new powers that just might help them confront the dragon hunters. Can the Green Ninja teach them how to harness their abilities?

The Merge (2)

On training day, Arin and Sora sneak out of the monastery to attend the Crossroads Carnival and uncover a villainous plot that tests their skills.

Crossroads Carnival

When the Bounty airship returns with no captain, Arin, Sora and Lloyd use clues to figure out what happened to Kai. Is it a trap... or something worse?

Beyond Madness

To save Cloud Kingdom, the Ninja must work together to send a terrifying tentacled beast back where it came from and close the Mergequake — and fast!

Writers of Destiny

When the Ninja meet their match in a Photac — an indestructible techno-beast — Sora believes that a mission to Imperium is the only way to destroy it.

To bust the imprisoned dragons out of Imperium, the Ninja will need to work hard, think fast and find one big exit! Unless the Photacs get there first.

Sora hacks into the Imperium logs to find Riyu. Nya and Kai explore a mysterious passageway. Lloyd leads an epic battle against an army of Photacs.

The Calm Inside

Ninja never quit! Nya, Kai and Zane give the battle against Imperium new hope while Lloyd uncovers a mystery hidden deep below the city.

The Battle of the Second Monastery

To stop the MergeQuakes from getting worse, the Ninja travel to the Temple of the Dragon Cores to learn more about something called "The Coalescence."

The Temple of the Dragon Cores

When the Ninja split up to find the three Dragon Cores, Arin and Lloyd take the airship but soon need help from a village of peaceful algae farmers.

Gangs of the Sea

Mr. Frohicky and Zane head to the Crossroads to locate a Wyconium coil. Elsewhere, Wyldfyre's pranks complicate her and Kai's Dragon Core quest.

Wyldly Inappropriate

Nya's Seeker Stones lead her and Sora to something they weren't searching for. As Zane's Assistant Keeper, Mr. Frohicky can't do anything right.

The Last Djinn

Sora and Nya search for the Dragon Core with a magical compass. Arin and Lloyd get put to the test in Mother Garden. Wyldfyre and Kai play keep-away.

They Call It Doom

In the Land of Lost Things, Nya runs into an old pal while Sora looks for an alternate power source to ward off a junkyard monster called "The Hoarder."

Land of Lost Things

Lloyd and Arin arrive in the Administration, where they learn the Dragon Core will be demolished if they don't act fast — and file the correct paperwork.

The Administration

While the Ninja try to figure out a way to bypass Imperium's energy barrier, Empress Beatrix tests a deadly weapon powered by stolen Dragon Cores.

Absolute Power

To expose Empress Beatrix's mistreatment of dragons to the naïve citizens of Imperium, the Ninja will need help... from a man on the inside.

We Are All Dragons

Empress Beatrix's rampage pushes the MergeQuakes dangerously close to the tipping point, unless the Ninja can work together — and save the world.

The Power Within

A phenomenon known as the Merge has caused many legendary realms to suddenly combine into one, but their union is unstable. A Spinjitzu Ninja Master must train a new generation of heroes to help find Elemental Dragons who can save the planet before the forces of evil use the same dragon energy to destroy this new world.
