3Below: Tales of Arcadia : Episode 19

When their planet's monarchy is overthrown by a coup, royal alien teens Aja and Krel flee to Earth accompanied by their brutish bodyguard.

After crash-landing in the town of Arcadia, the royals -- now disguised as humans -- search for suitable technology to power their ship.

Krel builds a mind-reading device in hopes of blending in with humans. Elsewhere, General Morando dispatches bounty hunters to track down the royals.

Royal super-fan Stuart offers to help eradicate an alien beetle infestation before it exposes the siblings' true identities.

The royals take a driver’s ed class, hoping to find parts for their ship. Instead, they're led on a high-speed chase with the Zeron Brotherhood!

A giant troll wreaks havoc at the school science fair, threatening to expose both the troll world -- and the royals’ true identities.

Aja and Krel are summoned by the school board to produce proper identification. Zadra discovers the identity of the traitor who aided the coup.

An incoming message from Akiridion-5 alarms Vex. Meanwhile, the arrival of bounty hunters ruins the royals' outing in the woods with friends.

The royal heirs look for Aja's missing serrator in the forest, where they mistake Trollhunter Jim Lake's Amulet of Daylight for her lost weapon.

In a daring heist, the royals and Stuart infiltrate a high-security military base in hopes of stealing the final part to power the mothership.

Aja decides to tell Steve she’s actually an alien, but her confession is cut short by a visit from the Zeron Brotherhood.

The royals celebrate their last day of school -- and on Earth -- with friends, but Zadra's arrival with revelations of betrayal shakes them to the core.

Alpha unleashes a barrage of attacks on the siblings, enabling Omen to hijack the ship and take the royal cores. Will this be the end of House Tarron?

Left vulnerable after Omen's attack, the royal heirs look to conceal their damaged ship but are soon confronted by the bounty hunter Magmatron.

Aja and Krel enlist Stuart to help find their former ally, who’s being held prisoner at a bounty hunter outpost on the moon.

With General Morando's invasion of Earth imminent, Krel tries to stop the fleet's advance with unwitting help from the kids of Arcadia.

Mother, the AI controlling the royals’ ship, reflects on keeping the peace between her quarreling family. Morando discovers a secret hidden on Earth.

Colonel Kubritz stages a phony quarantine of Arcadia High School in a ploy to capture the royals -- and their advanced weapons technology.

Unable to stop an asteroid hurtling toward Earth, Kubritz pleads with the royals to help destroy it by offering stored alien technology from Area 49B.

Krel builds a prototype device that will create a wormhole back to Akiridion-5, but Luug swallows it whole before it can be tested further.

The last defenders of House Tarron face off against General Morando and his army of Omen robots in an all-out battle for survival.

With General Morando searching for Gaylen's Core, Aja and Krel must travel into their parents' subconscious to learn the core's location first.

After learning the location of Gaylen’s Core, Toby calls Trollhunter Jim Lake, and Blinky advises the royals to consult the Soothscryer.

As the town of Arcadia gathers for the premiere of "Kleb or Alive," an army of Omens, led by an armored Kubritz, makes plans to lure out the royals.

With the fate of the universe at stake, the royal heirs and their allies must gather their forces for the ultimate battle to defeat General Morando.
