At Knightonia.

It been a hour and every civilians is panicking because a horde of new grimms are attacking the front gate with the Squirebot being useless.

At the same time the knights and Union students are heading towards the gate with Clay yelling at Lance.

Clay: "Are you happy Lance! You jinx us and now we're facing new grimms!" He said.

Lance: "How was I supposed to know that my comment would cause fate to summon these new grimms!" He said then both knights and Union students arrive at the gate that soon open for them but they are surprised to see these grimms are easily beating Atlas robots.

Axl: "Woah these grimms are no joke" he said.

Aaron: "yeah and when did Atlas robots get here?" He ask.

Wiess: "They actually was sent here in case of grimms but seeing these grimms easily taking them out proves that us heroes are needed!" She said then attempt to attack.

However to everyone surprised her glyphs are doing nothing against these new grimms as they produce heat.

Ruby: "That new" she said a bit excited.

Yang: "Doesn't matter let's show these grimms that they are weak against us!" She said then both Union students and the knights attack these grimms.

Meanwhile with Monstrox party.

Currently the three are near ruins which have strange and chaotic events going on.

Monstrox: "Ah these are cause by none other than the Book of Chaos" he said as both himself, Roodaka, and Jestro are in a barrier that he created.

Jestro: "I'm glad we're safe in here" he said a bit happy to be protected from the chaos happening around them. The three then look at the Book of Chaos.

Roodaka: "So how do we get that book?" She ask which Monstrox send a magic blast at the book causing it be trap in a orb thus stopping the chaos.

Jestro: "That was anticlimactic" he said which Monstrox shrug his shoulders and cause the barrier to vanish then grab the orb before adding it to the other orb that contains the book of evil.

Monstrox: "mm i think it time for us to get a vehicle as walking can be tiresome" he said then summon a few lava monsters including: Sparkks, Burnzie, and Beast Master.

An: give credit to the original artists.

Beasts Master: "What is your bidding master?" He ask.

Monstrox: "I want you to build us vehicles so that traveling can be quicker" he said with a polite yet commanding tone which Beasts Master nod then order the monsters to do what he ask.

Meanwhile back at Knightonia.

Currently the Knights and Union students are being beaten like they were dolls.

Rais: "How are we losing against these grimms!" She said throwing a magic attack that was then reflect back to her.

Akeno: "No idea! But these f*ckers are difficult to be killed!" She said as she send thousands of lightning at several grimms but those lightnings are absorb into the grimms which they use to cause Squirebots to shut down.

Bakugo: "Ahh! Just die you extras!" He said using his explosion quirk on multiple grimms only to reveal his attack done nothing.

Motoyasu: "Why is nothing working!" He said as he use his spear attacks but none of his attacks affect the grimms.

Itsuki: "Grr these grimms are cheaters!" He said as his bow attacks doesn't affect the grimms either.

Lance: "I admit this is difficult!" He said a bit overwhelmed by the strength these grimms have.

Inside Merlok library.

Two younglings enter the library to search for a strange signal they detected.

These two are Ava, a genius freshman, and Robin, a knight in training/mechanic.

The two then discovered that Merlok somehow magically become a program who was trying to warn about Monstrox.

Merlok: "I'm here to help!" He said.

Ava: "Alright. So let fight some monsters" she said picking up her pad.

Merlok: "Yes! Get ready for Nexo Scan!" He said.

Back at the gate.

It seems hope was all but lost for both knights and Union students when Ava suddenly spoke through Clay comms.

Ava: "Clay raise your shield to the sky. Now!" She said surprising Clay but with no choice he did and suddenly his armor begin to glow.

Merlok: "Nexo Power: Dragon of Justice!" He said.

Then Clay begin to slay the grimms with ease surprising both Knights and Union which the Star students growl.

It wasn't long until all five Knights managed to slay all the grimms thus causing the Star students to feel rage at how these Knights easily slay these grimms.

Afterwards it reveal that Merlok who become knows as Merlok 2.0 was alive and the civilians celebrate the victory of the Knights while Union Star students are enrage that the Knights is getting the credit. However what the kingdom doesn't know is that one grimm had survive and leave to report the situation.

A hour later.

Meanwhile with Monstrox group.

It wasn't long until Monstrox, Roodaka and Jestro are on a vehicle call the Evil Mobile driving towards the Lava lands.

Monstrox: "Stop! I'm sensing the grimm that I sent to Knightonia" he said which the Evil Mobile stop then the grimm reveal itself.

Grimm Nui-Rama.

This grimm then report what happened which Monstrox frown after hearing the report.

Jestro: "He can understand what that grimm is saying?" He ask which Roodaka nod.

Monstrox: "It seems Merlok is alive but now become a program and gave the Knights a new power call Nexo Power" he said surprising the two at this new information.

Roodaka: "Well despite this we still have the advantage as they haven't discovered the evil books yet" she said which Jestro nod.

Monstrox: "Perhaps but they will soon know and if Union get their hands on those books they will be a threat" he said then the Evil Mobile continue to drive on.

Meanwhile at the Land of Darkness.

At the same time Salem have gather her allies and discuss about Monstrox.

All for One: "So it seems the report that we received twenty years ago was true after all" he said.

Shalba: "Indeed but the question is why should we recruit this Monstrox into our League of Darkness?" He ask.

Pein: "Probably because Monstrox deserve it for the suffering he went through by Union headmasters. Plus he will seek revenge against Union" he said.

Ragyo: "Indeed and he's quite handsome~" she said licking her lips at a photo of Monstrox.

Zeldris: "Mm I wonder who his parents are" he said gaining the other villains attention.

Muzan: "why did you ask that?" He ask.

Zeldris: "Just wondering since there ain't a lot on his family from the report" he said which did peak the other villains attention.

Salem: "Good point but for now we wait till he reply to my messenger that I sent" she said gaining the villains attention.

All for One: "And who did you sent?" He ask.

Salem: "A new bounty hunter called Ronin" she said.
