The Battle Begins

The Battle Begins '''is the twenty-fourth episode of Tenkai Knights. It first aired on February 22, 2014 on Cartoon Network in the United States.'''

Plot
This episode begins with Beag and his army staring at the malfunctioning portal before the Tenkai Knights show up. The Knights nor Beag know what to make of the strange light, but they assemble their army and prepare to invade Vilius's fortress. Guardian Boreas then tells them the events that transpired in the last episode after crashing the Dropship into a plateau.

Meanwhile Granox pretends to be the leader of the army of the Corrupted, but Vilius is in a good mood so he decides to ignore it. Granox then asks about the battle, but when he finds out they lost, he asks if it was Slyger's fault. He then tells Granox how he failed to obtain the portal, but "have achieved something even better."

The Knights then find out that they will need to go back to Earth before the battle because of the malfunctioning portal, but a side effect takes them to an alternate dimension where Vilius has taken over and destroyed humanity. Boreas explains that this is a possible future if the Knights don't stop him and the two worlds from merging.

Chooki and Guren go to the library to check out books on history's greatest generals why Ceylan plays soccer and Toxsa does chores for their training. They all say their goodbyes in case the world should end the next day, but the only one who seems to understand what is happening is Wakemai.

Meanwhile on Quarton, Eurus questions Dromus's and Venetta's decision to "proceed as planned" even though Vilius had returned.

On Earth, Boreas and Mr. White are concerned that they cannot contact the other Guardians.

Vilius states that the battle is about to begin and everyone takes their positions. The Corekai make the first move and soon the Knights Robofuse into the Air Lancer Jet to destroy a big chunk of the Corrupted and the fortress wall.

They then split up, Bravenwolf and Tributon going after the Dragon, and Valorn and Lydendor going after the reassembly device. Soon Valorn and Lydendor are attacked by Granox and Slyger and Bravenwolf and Tributon are attacked by Dromus and Venetta. All the Knights, Granox, Dromus and Slyger go into Titan Mode, but Venetta doesn't. The episode ends with Dromus's and Bravewolf's swords clashed.
