At Haven Academy.

Currently the academy was peaceful when out of nowhere multiple Decepticons and Grimms attack the school.

An: Scorpion Decepticons.

An: I can't remember this female Decepticon so tell me if you do.

???: "DECEPTICONS! DESTROY THIS ACADEMY! FOR LORD UNI-TRON!" The leading female Decepticon said as both Decepticons and grimms follow her commands.

Inside Lionheart office.

Currently the headmaster of Haven himself is shock at what he been told by Salem.

Lionheart: "What do you mean that I'm no longer useful!" He said with fear as he's talking to Salem through a Seer.

Salem: "True you been helpful but now that Lord Uni-tron is in charge he find you useless and ain't needed for the downfall of Union" she said then the Seer grabbed Lionheart as the leading Decepticon bust through the door.

???: "Goodbye Lionheart" she said and kill him.

Once Lionheart is dead the Seer then let go and show Uni-tron himself.

Uni-tron: "Excellent work Cinder. Now go and get the relic" he said revealing that the former human Cinder is now a cybertronian.

Cinder: "Understood my liege" she said then walk towards the vault.

Outside Haven academy.

It didn't took long until all the students were capture or killed and is in the center of the destroyed academy.

However it wasn't long until Cinder walk out of the ruined academy with the Relic of knowledge.

Cinder: "That was easy. Now then students you can either die or join the Decepticons" she said then smile as she see that the remaining students all agree.

Suddenly a blast knock the Relic out of her hand which she growl then look only to pale as she see Optimus prime with Ruby on his hand.

Ruby: "Surrender Decepticons! You're outnumbered!" She said as it reveal that several Union, Atlas airships, Autobots, Avengers and Justice League surround them.

Cinder: "Tsk never as we came prepared!" She said then out of nowhere multiple Decepticons warships appear and begin firing upon them.

Ant Man: "We're being overwhelmed! We have to retreat!" He said.

Flash: "I got the Relic!" He said only to be punch in the face by a new enemy.

Tony: "What the! It Ultron!" He said.

Lady Ultron: "Correction my drones and sentries" she spoke through one of the new enemies which shock everyone.

Cinder: "Get the relic!" She said which one of the drone did then the Decepticons teleport the Haven students onto the warships.

Ruby: "Wait. Cinder!" She said recognizing the voice which shock everyone that a former human is now a cybertronian.

Cinder: "Yup~ Now then hope you survived~" she said then she teleport the Decepticons and grimms away as the warships flew away.

Suddenly they heard ticking which they realize that Cinder planted a bomb.

Optimus prime: "Retreat!" He said then everyone run.

Once far away they see Haven Academy blow up into dust.

Ozpin: "This is bad" he said squeezing his cane with anger as he realizes that they lost once again.
