Soundwave Soulmate Prompt? You can see what your soulmate draw on their skin
Sorry this was super long lol!
TFP Soundwave X Reader Soulmate AU
Soundwave had thought for a long time that he would be forever alone. He’d watch as everyone else got small little marks on their plating that would fade in a matter of hours, while he had none.
He believed that some just never got soulmates- him included. So when after millions of years a small doodle appeared on his plating, he was shocked. He quickly made his way to his berthroom so no one else could see.
Once there he inspected the mark. It was a very-well drawn image of the Autobot’s insignia. He quickly felt irritation pull at his spark. Was his soulmate an Autobot? He hesitated for a moment before drawing a Decepticon symbol on his arm.
You were sitting in the Autobot’s base when you felt an odd sensation on your skin. You looked down to see a Decepticon symbol on your arm. It looked like someone had scratched your arm to make the symbol.
You yelped in fear and held your arm out like it was burned. Ratchet’s eyes quickly fell to you, being the only other in the base.
“What’s wrong?”
“The-there’s a thing on my arm.” He walked over and gently turned your arm over.
“You shouldn’t be drawing this on your arm.” He scowled.
“I-I didn’t! It just- just appeared there!”
Ratchet’s eyes immediately furrowed. While humans didn’t have the concept of sparkmates, Cybertronians certainly did. The fact a human could be affected stumped him.
“Did you draw anything on yourself?” He asked. You pointed dumbly to the Autobot symbol you had drawn on yourself a few minutes ago. His frown only deepened, realizing that your sparkmate must have been a Decepticon.
“What? What’s wrong?” You pleaded in fear. The other Autobots returned to the main hangar as you loudly interrogated Ratchet.
“I fear that you have a Sparkmate- which I didn’t know was possible for a human.”
“A what?” You demanded.
“A sparkmate?” Optimus questioned. “How is that possible?”
“I’ve never heard about this before.” Arcee commented.
“It must be a Decepticon, look at the markings!”
All of the bots began talking about it as you grew more panicked. You yelled out unintentionally. “SOMEONE TELL ME WHAT’S GOING ON!”
All eyes fell on you with guilty looks. Optimus gently placed a few digits on your shoulder. “It appears you have a… sparkmate. It is what you humans would refer to as a ‘soulmate’. A sparkmate, however, is someone you are actually bound to- not just someone you feel an emotional pull to. Anything you draw on your skin will show up on your sparkmate. Before you, there has never been a recorded case of an organic and a Cybertronian being bonded before”
You sat dumbfounded. You looked at your skin where the Decepticon symbol was fading. “So, this is like. I don’t know. This is a Decepticon? That I’m bound to?”
Optimus nodded solemnly. “I think it may be best for you to refrain from drawing on yourself. We have no clue who you’re bonded to- and it may put you in danger. Many Decepticons have killed their sparkmates to prove their loyalty to Megatron.”
The fear on your face was obvious. When you went home, you could feel nothing but fear. What if they caught you? What if they killed you?
You were about to go to sleep when the odd sensation returned. On the inside of your hand, large letters appeared. They were foreign to you, being Cybertronian.
You tried to resist the urge to write something back, but you ended up putting a question mark on your wrist.
Soundwave had realized you were a human when the question mark arrived. He had always wondered why he didn’t have a sparkmate- and now he knew. He had no idea how to feel about it, either. So he went to the one person he could always confide in- Megatron.
“They’re human?” Megatron thought. Soundwave thought Megatron would laugh, but he instead seemed thoughtful. “I didn’t know something like that was possible. If you wish to collect them, I will not stop you.” Megatron patted his oldest friend on the shoulder who only tilted their head.
Megatron noticed their confusion. “This will not leave this room, understand?” Soundwave nodded his head. “I had a sparkmate. It was before the war when I met him in the mines.” Megatron’s face pulled into one of sadness- something he’d only seen once on his leader’s face. “We had spent a few million years together when they became one with the Allspark. Energon deficiency. The senators refused to give us the energon we needed to survive- only enough to keep us running. We tried to save him, but there was nothing anyone could do.” Megatron grabbed his shoulder once again and looked at him in his faceplate. “Your sparkmate is destined to be with you. Don’t let them slip through your digits- human or not. You’ll regret it for the rest of your life.”
Soundwave was shocked by the advice given to him by the warlord. He trusted his advice nonetheless, and began searching for you. He drew on his arm plating, a simple question.
You were at base again when you felt it. You looked down to your wrist to see a name written in English- Soundwave. Your face went pale when you realized just who your sparkmate was. You read all about him and the atrocities he’d committed. You felt your head grow light as you began to sway.
Bulkhead called out to you when he noticed you walking weirdly. You looked up at him with glossed over eyes and he just barely managed to catch you with a servo before you collapsed.
“Ratchet!” He yelled. Ratchet and the others immediately ran over. As Ratchet looked you over, he noticed the writing on your wrist. His face contorted in fear.
“What is it, old friend?” Optimus’ deep voice sounded from beside the medic.
Ratchet almost couldn’t get his words out. “Their sparkmate is… Soundwave.”
Concerned looks flashed on everyone’s faces. They knew just how brutal he could be- he was a gladiator before the war after all. “We must have surveillance on them at all times. If Soundwave is contacting them through their bond, it cannot be good.”
When you woke up, they explained everything. You couldn’t help the fear you felt at the idea of someone so terrifying trying to contact you. However, the messages left were oddly… sweet. He would often ask how your day was, or what your favorite color was. When you were at home you would write on yourself- and this went on for months.
You actually began to enjoy talking with the silent mech- just as much as Soundwave. He was actually really funny, but also awkward. He often talked about his son, Laserbeak (and whatever Laserbeak got into that day).
One day Soundwave asked you the question you’d been expecting for a while. “When can we meet?”
You bit your lip as you thought of it. You weren’t even sure if you should meet him. Despite everything in your brain telling you not to- that he was just leading you on or he was going to hurt you- you wrote back. “Tonight.”
You went out back to avoid being seen by Bulkhead. You looked back at his vehicle mode from the small hill you climbed up in guilt. You looked back over the hill, and made your decision.
You walked for a few miles. Your legs felt as if they were on fire. You plopped down onto the ground when you heard it- a quiet whooshing sound. You turned around to see an odd looking jet coming your way.
A Decepticon transformed midway and flipped to the ground, landing on his two pedes. You looked at him, and made eye-visor contact. He was beautiful- from his frame to his purple glowing biolights. He, too, thought you were beautiful.
You both took a step towards each other. Before you could say anything, he scooped you up. You both only looked at each other as he held you close to his visor- and it just clicked. It felt right to be in his hand.
Before you could stop yourself, you spoke. “I love you, Soundwave.”
Soundwave pressed his faceplate against yours, signaling his love for you too. With that he whisked you away back to the Nemesis. For now, you’d keep your new-found relationship secret from the Autobots- but that would only last for so long.
