At Union Academy.

It took three weeks but Union rebuilt the academy but currently the star students, Martha team, and other students are in the headmasters office.

Ozpin: "Students we had received a message from Schnee Dust Company about an attack from one of their massive mines. They ask us to go to this mine and stop this attack" he said.

Ruby: "Um mr Ozpin what kind of mine is this? I know dust and Energon are important but what kind of mine are we going after?" She ask.

Optimus: "This mine is massive and have both resources you mentioned miss Rose. Which is why Bumblebee and his team will be helping you" he said surprising the students at how serious this mission is.

Rias: "What? But why? Simply we can defend and get this mine on our own" she said only for her brother to slam his hand on the table.

Sirzech: "This is no longer a game sister! We ain't sure if the Decepticons are responsible since they went quiet a week ago after Uni-tron broadcast. So take this serious" he said surprising her at how dead serious her brother is.

Bakugo: "Pft please those scraps will be easy to handle especially if that weakling is leading them" he said only for Nezu to give him the death glare.

Nezu: "You will die if you don't take the Decepticons serious you brat" he said shocking the students at his tone.

Izuku: "Yes headmaster Nezu" he said covering Bakugo mouth.

A hour later.

It took a hour but both students and Bumblebee team arrived at the mine but they are shocked to see dead Atlas soldiers and dead Schnee employees too.

Asia: "What kind of monster would slaughter these innocent people" she said.

Bumblebee: "I'm not sure. For now students stay behind us" he said then they walk in the mine where they noticed that there's not any dead miners but only Atlas and Schnee employees.

Wiess: "Where are the miners?" She ask.

Strongarm: "I'm not- Wait this is strange" she said finding scratch marks near the corpses.

Tenya: "Are those scratch marks?" He ask.

Strongarm: "Yes but it look recent too" she said frightening a few students.

Asia: "Did grimms attack the mine?" She ask a bit afraid.

Bumblebee: "No otherwise there miners corpses" he said as they walk.

It wasn't long until the group discovered the digging site only for they to be shocked at the fact the miners are helping the Decepticons and Insecticons mining the resources.

The group hide behind a wall to avoid being detected.

Blake: "Are the faunus helping with the enemies?!" She said with a whisper tone.

Sideswipe: "This doesn't make any sense. Decepticons and Insecticons wouldn't work with organics beings" he said.

Grimlock: "Maybe the faunus are forced to work?" He suggested only for them to hear a faunus miner spoke which they look to see something that shocked them.

Faunus: "Hey Steve where do I put this crate of Energon at?" A random faunus miner ask a Decepticon.

Decepticon (Steve): "Over there at the other entrance" a Decepticon said pointing at another entrance.

Faunus: "Thanks. Also Stella how is Lord Uni-tron doing?" The same faunus said talking to a female vehicon that is sitting on Energon.

Stella: "He doing fine and I can't believe those Schnee employees and hired Atlas soldiers would abused you all" she said shocking the Autobots and students.

Faunus: "Well it much better than working with you Decepticons as you're helping us out instead of watching us" the same faunus said as he walk to the other entrance.

Honeybee: "... Did you knew about this Wiess?" She ask.

Wiess: "No but I'm feeling bad that these faunus were abused" she said with honesty.

Cardin: "Tsk doesn't matter we teach these traitors that siding with the Decepticons are their worst mistake" he said then both himself and his team charge at the Decepticons and miners.

Bumblebee: "Dang it!" He said as Cardin and his team blow their cover.

Stella: "Oh look Union brats and Autobots are here" she said which cause every Decepticons, Insecticons and miner to look at the group.

Bumblebee: "Autobots and Students attack!" He said then the students and his team attacks.

Stella: "Tsk SHATTER! AIRACHNID WE NEED BACKUP" she said then exiting the other entrance is  two Decepticon who appearances cause the perverts to drool.

Shatter: "Ah so Union sent Bumblebee, his team, and the Union brats to this mine" she said.

Airachnid: "And judging from their attacks they aren't prepared against us" she said.

Arcee daughter, Maira look at Airachnid with rage in her eyes.

Maria: "You! I'm gonna scrap you for what you did to my mother in the past!" She said running at Airachnid only for the Decepticon to grab her by the neck.

Airachnid: "tsk like mother like daughter" she said knocking her out then throwing her at a wall near Honeybee.

Honeybee: "Maria!" She said and about to run to help but Decepticons attack her.

Bumblebee: "Dang it! We're outmatched!" He said realizing the situation then see Issei about to do something stupid.

Issei: "Dragon" he couldn't finish when he was shoot in the d*ck causing him to scream in pain as it reveal the miners are using holy blessed guns.

Blake: "Why would you help the Decepticons!" She said looking at the Faunus miners.

Faunus: "They free us and treat us as equals!" The miners shout and shoot at the students and Autobots.

Cardin was about to attack when a Decepticon slice off his leg causing him to scream in pain, shock and horror.

Bumblebee: "Retreat!" He yell seeing several students getting injured then both Autobots and students run while dragging the injured and unconscious.

It wasn't long until the Autobots and students successfully escape which Decepticons, Insecticons and miners all cheer at their first victory.

Airachnid: "Heh this is only the beginning" she said.

Back at Union.

It took two hours but Bumblebee and the other students, that ain't recovering, stood in front of the headmasters and reported what happened.

Optimus: "How did they avoid detection? And got the miners to join them" he said.

Bumblebee: "I'm not sure but from what we see it seems we need to do a investigation on Schnee Company and Atlas" he said.

Ozpin: "If we did then we need evidence and currently we don't have none" he said which shock Martha team.

Martha: "No evidence! We heard how a whole bunch of faunus confessed Schnee employees and Atlas soldiers abused them!" She said.

Optimus: "I know but confessions ain't enough" he said shocking his own daughter.

Martha: "I can't believe this" she said then angrily leave the office with her team following.

At the Land of Darkness.

Currently Uni-tron heard the report about the mine that his Decepticons had captured and is please with how successful they defend it.

Uni-tron: "This is only the beginning Union and Autobots. As you will face my wrath on what you did to my father after his self banishment" he said with his eyes glow purple and blood red.
