Author's notes:

Hello! This is a Transformers AU crossover with Percy Jackson. Here's all of the basic things you need to know.

This takes place almost right after Blood of Olympus ended. Ignores all other series

Logos Prime is one of the Thirteen, but isn't Soundblaster.

This transformers universe combines elements from multiple continuities, including Transformers Prime, various IDW sources, G1 cartoon, Bayverse, and Animated. These range from weapons, to lore, to personality, to abilities, and alt. modes. I took some liberties with the story and the characterizations.

I reworked this chapter to be better, but unfortunately made it twice as long as most chapters I write. Sorry.

Soundwave

It had been decades after the Great Cybertron War ended. While I still lead the Decepticons, I had lead them on a path of peace and equality, not the path of violence and destruction that Megatron was leading us to, and my loyalty made me overlook this. Now, long after the War, I had recently gained interest in researching my past.

Even before the War, I had no interest in investigating my past. The farthest back I could remember was lying in an alleyway, desperately trying to drown out everything I was hearing. That was the day Laserbeak, Buzzsaw, and Ravage found me and taught me focus. That was the day I became Soundwave.

I never bothered in trying to remember past that day. Partially because I didn't want to, partially because I couldn't. Every time I tried to remember before that day, my mind just came to blanks. I assumed my past was nothing but traumatic, so I had no problem with suppressing memories I already forgot.

When the War ended, me and the other Decepticon veterans were sent to live in Trypticon Station. I understood me becoming leader, as I lead the Decepticons in their final days.

However, I didn't understand was that leadership came to me too naturally, almost like second nature. I had never thought about being a leader before, and had no memory leading. So why did leadership seem so easy for me?

I wanted to consult Optimus Prime. Deciding I wanted his help to investigate my past, as he was one of the most educated librarians still alive, as well as being the last prime.

I decided to leave Barricade in charge while I left, as he would be the most likely to maintain order without the station devolving to violence. Just in case, I put in a request for Ultra Magnus to pay a visit and help Barricade maintain peace. After all, a crowd of Decepticon War veterans could be quite... rowdy.

I had to leave my weapons at the station per Autobot protocol, but I made sure my cassettes were with me. I never go anywhere without them if I can help it.

As Prime and I flew to the Cybertron to comb through the census records, I felt this odd sensation, like something was calling to me. Something, or someone, I couldn't explain. It wasn't something I deemed important, so I merely ignored the feeling.

We arrived at Cyberton in a short time. We ventured to the archive building. Autobots did double takes when they noticed me wearing my Decepticon symbol, but Prime reassured them I was only searching for my records. After a bit of a walk, we arrived at the archive building.

Combing through the records, I frequently found myself tempted to read stories relating to one of the thirteen original Primes, Logos Prime. I was perplexed, as I had no previous interest in the Lost Prime, yet I always unconsciously reached for texts relating to him.

When I was finished, I held both my census records and various texts of Logos Prime. I sat down to read, focusing all my attention on reading to utilize my enhanced information gathering skills. I barely noticed Prime walk up to me.

"Soundwave, you seem to have picked up quite the number of texts? Are you sure these are all your census records?"

"Affirmati-... no. I have picked up records I found of me as well as texts relating to Logos Prime." 'Strange, why was I about to say Logos Prime's records were also mine? Was I not paying attention?'

Prime hesitated to respond, clearly catching my halted claim.

"...Well, then. I was unable to find much on you, so I researched your cassettes. Ravage, Laserbeak, and Buzzsaw, specifically. I know Rumble and Frenzy are your creations."

"You do not need to do so, as I already know that they were strays before they met me."

"Still, I would like to read into their records in case it reveals any new information."

"Thank you, Prime."

We sat in silence for a time. My records revealed no new information about me, only restating what I already knew. I finished reading my records in seconds. Reading the records of Logos Prime took far longer than reading my records, however I did finish them. Eventually, Prime spoke.

"I haven't been able to fond any new information in these texts. Have you found anything yet?"

"Negative. Although, I have found Logos Prime's texts interesting, so-"

I finally took a good look at all of the images of Logos Prime. I had initially ignored them in favor of speeding up the process of reading the texts. When I looked at him, however, recognized him. Logos Prime looked similar to me.

At the same time, the thing that was calling me grew louder. I could no longer ignore it. Before I could process anything, I found myself standing on what seemed like the courtyard of a fortress. I looked around, but only saw twirling patterns, strings, and light. The fortress itself looked old, yet advanced at the same time. Some of it looked like it was made from the wreckage of a ship.

I walked to the front entrance, intending to announce myself. Strangely, the doors opened for me. Inside the fortress looked even larger and more confusing than the outside. Yet, I was able to navigate to what looked like a throne room.

Sitting atop the throne was one that looked like me, except, different. He was silver, and had armor with wings. I knew he was Logos Prime.

He introduced, "Greetings, my heir."

"Heir? What do you mean?" I asked.

"Ah, you see, I've been looking for an heir to inherit my powers. One I could trust. Yet, aa long as I've looked, I never found them. Until I found you."

"Me?"

"I wanted one worthy of my power. One who was strong, intelligent, and responsible. I wanted the one to brought peace to Cybertron."

"If that is so, you should have chosen Optimus Prime, should you not?"

"Don't be modest. It is true he was the one to negotiate, to build a peaceful society, to grant Decepticons amnesty. But who let him?"

"I am afraid I do not understand."

"Optimus could make as many negotiations, speeches, plans, and offers of peace he wanted. But he couldn't bring peace. The only one who could was the one who brought the Decepticons to peace. You brought the end of the War. You brought peace."

"I still do not understand. If you chose me to be your heir since the War ended, why would you wait until now? After all, the War has been over for decades."

"I needed you to learn."

"Learn what?"

"About me. I couldn't let you be my heir while being clueless about the power you would inherit. Now do you understand?"

My confusion cleared. "Affirmative." I answered.

"Thank you. Now, I shall pass my powers onto you."

"According to your texts, you could travel Universes. Could you not return home?"

"I'm afraid I cannot. Being in the undead universe for this long has done things to me. I fear what I may become if I return."

"So you are trapped?"

"Yes. Now, be still, as this process may hurt."

"Affirmati-"

I could not fully answer before power surged through me. It was painful, as he said. I felt my systems overloading, circuits nearly frying. Then, just as quickly as the pain started, it subsided, replaced with a feeling similar to what humans call an adrenaline rush. I had a level of energy I had never had before. I felt as if I could face any threat.

I looked back at Logos, and he no longer had his armor or wings. He looked like I did before hand.

"You feel it, don't you? The power. The possibilities. The memories."

"Excuse me?" I questioned.

"Ah, you have not received my memories."

"Received your memories?"

"You can't learn everything from books. You need experience."

As if on command, memories surged in my mind. It felt painful, but not nearly as much as I anticipated, possibly from my experience with downloading large files of information during my time as a spy.

"I have shared with you all the memories you need to control your newfound power. However, I cannot allow you to return to Cybertron just yet."

"Why not?"

"You seek knowledge of your past, don't you?"

"Affirmative. But, would it not be better to send me where I would find this information?"

"That is where I'll be sending you. A place where you will find this information."

"How?"

"You see, any records of your creation have been erased from your world. The only way to find your past is to be guided by your dreams."

"How could I dream if I cannot sleep?"

"Where I'll be sending you, you will be able to find the Dreamer. There, he will be able to reveal your past in a dream-like event. Understand?"

"Affirmative. Although, can you help me find this 'Dreamer'?"

"I don't believe it should be too hard for you to recognize them."

"But how will I find them?"

"To put it simply, you won't. They'll come to you. Although, their entrance won't be very subtle. Got it?"

"Affirmative."

"Perfect. Now, take this."

Logos Prime walked over, holding something. He handed it to me, and I saw it was a defunct Matrix, his Matrix.

"Now, you shall go to the world I have detailed. You will find the universe coordinates in the transferred memories. I have made sure your cassettes and weapons are with you, and you have ample means to produce energon. Farewell, Soundwave."

I stated, "Farewell, Lost Prime."

He opened a Universe Bridge to the disclosed world I would find my past in. Before I walked theough, the former Prime called out, "By the way, be careful. The people of that world can be quite the handful.

"Affirmative."

With that, I walked through the portal. The Lost Prime may have a twisted sense of humor, as he put me high in the sky. I couldn't transform fast enough, so was stuck falling like a meteor. I could only aim myself at the shores of the camp.re
