Last time laserbeak kidnaped Ruby Rose and the Autobots and some of the humans came after only to discover it was a trap by Megatron and they were forced to surrender and Cinder Fall betrayed Megatron by putting him in stasis lock. The hunters and huntresses along with the Autobots were put in a prison cell which neutralized the hunters' and huntresses' aura and semblance and then Blake hold the story of the silver-eyed warriors which Ironhide said, it sounded the story of the Matrix of Leadership.
Now for the for where we left off.
Ruby:So what is this "Matrix of Leadership"?
Optimus Prime:Let me show you.
Optimus Prime opens his chest doors to show the humans the Matrix of Leadership.
Jaune:It's unbelievable.
Yang:Something with extraordinary power.
Blake:I've never seen anything like that.
Ruby:It sounds more heroic than all the silver-eye warriors combined.
Lie Ren:I'm speechless.
Optimus Prime closes his chest doors.
A Flashback appears
Optimus Prime tells the story of the Matrix of Leadership to the Hunters and Huntresses.
Optimus Prime:Eons of ago he plant Cybertron was a factory built by the Quintessons to manufacture robots which are ancestors of the Autobots and Decepticons in time the Quintessons have their robots to have intelligence so the machines can manufacture them selves.
Optimus Prime:Before long the machines grew too lazy and greedy.
Optimus Prime:There were simpler ways for the Quintessons to perform their slaves.
Optimus Prime:The Quintessons simply recycled it on spot.
Optimus Prime:The Quintesscons also use the robots to entertain them.
Ruby:So the Quintessons are octopus like robots with 8 heads.
Optimus Prime:That's correct.
Optimus Prime:The machines were pitted against one on another gladiatorial combat but some of our ancestors founded this combat pointless.
Optimus Prime:Some of them put a stop to it but we failed.
Optimus Prime:But the seeds of revolt planted and with one day yield terrible harvest but the quintessons fail to grasp.
Blake:So your ancestors rebelled against your creators?
Optimus Prime:That is correct.
Optimus Prime:But their robots gained feelings and emotions and felt the difference between freedom and slavery.
Optimus Prime:After the Quintessons were driven off Cybertron, for a time the robots lived in harmony but this didn't last the former consumer goods called them selves Autobots saw a peaceful existence while the military hardware wanted conquest and they got their way.
Weiss:Let me guess the military hardware were the Decepticons?
Optimus Prime:Correct Weiss.
Optimus Prime:For centuries they terrorized the Autobots.
Optimus Prime:Our ancestors knowing they can't defeat the Decepticons with firepower they turned to stealth and invented the art of "Transforming", the Autobots ruled for many centuries.
Lie Ren:So that's how transforming started.
Optimus Prime:Correct.
Optimus Prime:But in time the Decepticons also learned how to transform.
Optimus Prime:This one fateful night, far below the city, Megatron was born.
Optimus Prime:The Matrix was passed to Alpha-Trion the oldest of Autobots who kept it safely hidden for many years until the next Autobot leader appeared.
Optimus Prime:A gentle robot known as Orion Pax who fared to become Optimus Prime and so began the Third Cybertronian war which reached to this day.
Yang:You were once a robot called Orion Pax.
Blake:How your were reformed into Optimus Prime.
Optimus Prime:Well Megatron damaged me and the Aerialbots took me to Alpha-Trion and he rebuilt me as Optimus Prime.
Ruby:How they find you broken.
Silver Bolt:Well we we're tricked by the Decepticons and got sent back 9 million years while in Cybertron and we encountered Orion Pax and Ariel were then Megatron attacked them and damaged them then we took Orion Pax to Alpha-Trion where he rebuild him as Optimus Prime and then he send drones to Ariel bring her to Alpha-Trion where he rebuild her as Eltia-1 and then we had to blew up the energon storage to prevent a time paradox lucky Autobots brought us back to the present in time before the bomb went off.
Weiss*angry at Optimus Prime* Why you use the Matrix to obliterate the our enemies.
Optimus Prime:It is only used as last resort if all hope is lost and when we're in a darkest hour.
Ruby:Darkest hour?
Ironhide:Darkest Hour as in where all hope is lost and when the enemy is about to win.
Yang:Oh
Ruby:How are we going to get out?
Hound:Leave it to me.

Also I did little references from Transformers the movie (1986),The Transformers episode:Faces of Darkness part 4, Transformers Rise of the Dark Spark, and Beast Wars Transformers.
Also the next RWBY crossover after RWBY meets the Transformers part 5 will be either RWBY meets the Doctor from Doctor Who, RWBY meets the justice league, RWBY meets the Transformers 2:Beast Wars, RWBY meets Robotcop and Terminator, RWBY meets the Enterprise crew, or RWBY meets the memes and the creepypastas.
