Season 2 - Episode Guide

After barely escaping Krytus, the BF5 regroup on Earth in order to repair the Hub and upgrade their vehicles.

On a recon mission to Sark, Zoom confirms Vert's worst fears: that Zemerik is up to his old tricks and is attempting to rebuild his Blue Sark army. But Zoom also discovers something much more terrifying: that Krytus and Kytren aren't dead after all. It appears they've come back from the dead!

Sage gets a distress signal from a MOBI that crash-landed beneath the surface of the Vandal Ocean. And it turns out it's carrying a valuable cargo: Blue Sentient Data-Logs!

When Grimian – a powerful Ape Vandal – snags the battlekey in a battlezone, he challenges Kalus for leadership. Kalus is forced to defend his "crown" (the Talon of Vandal) in the ritual of Kio hakoko – a series of difficult challenges.

Thanks to a tip from Zemerik, the BF5 head to a Red Sark Moon in the hopes of linking up with a mysterious resistance movement that is giving Krytus and his Red Sark army some difficulty.

When Sage has a disturbing nightmare about a mysterious artifact known as the Double-Helix Crystals, she orders the BF5 to find them before The Crimson One can get his hands on them. If he does, he'll be able to release the frozen Red Sentient civilization, destroy Sage, and achieve his goal of ruling the multiverse.

The BF5 have survived the initial onslaught of the Red Sentients and decide it's about time to turn the tables on their new enemies. They're going to take the initiative by attempting to destroy Kytren's respawn chamber. If they do that, the Red Sentient will be unable to resurrect and will be destroyed forever. Then, it's just a matter of picking off the remaining four, one by one.

The BF5 discover a battlezone that contains a cave full of Blue Sentient shells. Guarding them is a small Diad named Quardian, who used to be the servant of an ancient Blue Sentient named Boralis.

Ages ago, the Blue Sentient Council of Five fired a terraforming pod in order to rapidly build a new homeworld for the Blues. Unfortunately, it went astray and disappeared in the depths of the multiverse…until Sage finds it!

While searching for a secret backdoor portal to the Red Sentient Homeworld, Vert and Tezz are led, instead, to a secret factory on Planet Vandal.

While battling the Vandals, a freak fusion accident causes Sherman and Grimian's brains to switch. So unbeknownst to the BF5, they accidentally take Grimian (in Sherman's body) back to Earth, while the Sherman (in Grimian's body) stays on Planet Vandal…

When an earthquake accidentally dislodges the Mouth of the Dragon – an ancient structure designed to seal a quantum flux tear – Zen is drawn into the Red Sentient homeworld and pursued by Krytus and his team. Fortunately, he sends an SOS to Zoom and the BF5, who immediately set out to help him.

When Krytus creates a Pulse Scanner – a device capable of locating Blue Sentients with interdimensional sonar – the BF5 must figure out how to destroy it before he uses it to locate Sage on Earth.

While hunting down the Red Sentients, the BF5 catch them in the middle of one of their nefarious plots: they're trying to take out Rawkus – the Eternal Equalizer – so they can dominate the multiverse.

While fighting the Red Sentients and trying to destroy Krylox's respawn chamber, Vert and Zoom attempt to fuse into the SkyKnife. The only problem is, when they emerge from the fusion vortex, they're no longer in the battlezone, but in the Shadow Zone instead!

The BF5 discover that Krytus and the Red Sentients are hunting for a rare and nearly extinct beast: the legendary Magmatrox! The beasts used to roam the multiverse by the thousands, but were hunted to the verge of extinction by the Reds in ancient times; the Reds used the beasts' rhinoceros-like horns to enhance their psychic powers. Sadly, Krytus is hunting down the last known Magmatrox and it's up to the BF5 to stop him!

While investigating Krytus's ancient interrogation zone, the BF5 discover a surviving Blue Sentient – Sage's old mentor and a former member of the Council of Five! Not to mention the twin brother of Kytren.

The BF5 join forces with an unlikely ally: Zemerik! He has intel that Krytus is trying to activate an ancient factory battlezone that will allow him to upgrade his Red Sark army and become unstoppable. Zemerik has a special virus that he can upload into the zone in order to stop Krytus. But he needs the BF5 to give him access to the battlezone so he can unleash it.

While the BF5 fight their enemies in a battlezone, Vert is saved from destruction by a mysterious warrior who intervenes. Turns out the mysterious warrior is Jack Wheeler – Vert's long lost dad!

While Vert and Agura attempt to fuse during a battle, Krytus rams Agura out of the way and is accidentally drawn into the fusion vortex behind Vert. Krytus' anti-matter energy reacts with the fusion energy, causing Vert and him to fusion jump into the Shadow Zone!

While investigating a mysterious signal on Planet Vandal, the BF5 uncover a shocking truth: that Grimian has been secretly working with Krytus and the Red Sentients to overthrow Kalus and form a grand alliance.

When Sage starts acting suspiciously, Vert follows her into a battlezone, only to have his suspicions confirmed by, of all people, Krytus. Krytus convinces Vert that Sage is actually more dangerous than he is!

To weaken both Zemerik and the Reds, Sage attempts to create an anti-Sark super virus. If successfully manufactured and administered, all the Sark – both blue and red – will be rendered useless, leaving Zemerik and the Reds without armies.

The BF5 work with their old Kharamanos ally, Tromp, to deliver a debilitating blow to Kalus and his Vandals. They plan to covertly penetrate a caldera in the middle of the Vandal homeworld that is the main power core of the planet and plant a Phase Nullification Bomb. When detonated, it will destroy any Sentient-based technology on the planet – effectively taking out all the Vandals' vehicles and weaponry.

When Krytus and his team figure out a way to unfreeze The Frozen Ones – the millions upon millions of Red Sentients caught in the Double-Helix Stasis Field – the BF5 must act quickly to balance the playing field. Vert realizes that there's only one way to do that – by reuniting the Blue Sentient minds with their shells and restoring the entire Blue Sentient civlization.
