Headcanons TMNT 1987 Shredder with Fem!Reader
His obsession with revenge against Splinter and the Turtles would always come first. If your goals or morals ever conflicted with that mission, you'd quickly learn where his priorities truly lie.
Trust would be a constant battle — he trusts almost no one completely, and there'd always be a flicker of suspicion that you might betray him, no matter how much history you'd built.
Half of your relationship consists of playing referee between Shredder and Krang. When they start bickering over who gets to use the trans-dimensional portal, you are the only one who can step in, hand them both a cup of coffee, and tell them to focus.
The Technodrome is constantly getting stuck in terrible locations—the center of the Earth, under the ocean, or freezing in Dimension X. You are perpetually wrapping yourself in blankets. Saki, surprisingly, will use his cape to wrap around you when the heating system fails (again).
Shredder is genuinely thrilled to have someone around who actually possesses more than two brain cells. You are the only person he trusts to double-check his blueprints for his latest ridiculous "Turtle-destroying" device.
Every time the Turtles thwart his plans, he storms back into the control room throwing an absolute tantrum. Your job is to sit back, let him yell about "those wretched, miserable amphibians!" and dramatically pace the floor until he runs out of steam.
“I require your company!”
Saki has a massive ego that bruises easily. After a particularly embarrassing defeat (usually involving getting covered in garbage or slipping on a pizza), you are the one who tells him his plan was actually brilliant and it was purely Bebop and Rocksteady’s fault that it failed.
His mood instantly improves when you suggest a slightly less convoluted plan for next time. If you validate his evil genius, he looks at you like you hung the moon.
Saki doesn't do "soft" romance very well. Instead, his declarations of love are intense and highly theatrical. He will point dramatically at a monitor showing a conquered city and declare.
"Once I rule this world, you shall be by my side!"
He is incredibly vain about his armor. It takes a long time for him to feel comfortable enough to take the helmet off around you. When he finally does, it's a sign of absolute trust. You probably have to help him polish the metal blades on his gauntlets on Sunday afternoons.
In the quiet hours when Krang is scheming and the Technodrome hums softly, he talks about the old days in Japan, his clan’s fall, and his burning need for respect.
His love language is aggressively protecting you. If a Foot Soldier bumps into you or Krang snaps at you, Shredder is immediately in their face.
"Do not speak to her in that tone, you miserable brain!"
When dealing with Bebop and Rocksteady, you are definitely the good cop. Shredder will chase them around the room threatening to mutate them into something smaller, while you just sigh and hand them a mop to clean up whatever they broke.
The mutants actually really like you because you stop the boss from yelling at them 24/7. They occasionally bring you stolen trinkets from the surface, like a slightly crushed box of chocolates as a thank you, which Saki will immediately confiscate to "inspect for Turtle traps" before giving it back to you.
Dates are either ridiculously extravagant or comically villainous. Candlelit dinners in the Technodrome’s command center while Foot soldiers serve mutated sushi, or “romantic” evenings watching the Turtles fail spectacularly on surveillance monitors while Shredder monologues about his latest genius plan. He once tried to take you to a fancy restaurant in New York… by having the Foot Clan clear out the entire building first.
Jealousy Level: over 9000. If any of the Turtles so much as look in your direction, Shredder goes full drama king. “You dare speak to my woman, you wretched reptiles?!” He’ll dramatically pull you against his armored chest mid-battle just to make a point. You’ve had to physically stop him from challenging Leonardo to a duel over a polite “Are you okay?” from the blue-masked turtle.
He insists you learn self-defense from the Foot Clan’s best trainers, he supervises every session with a critical eye. He wants you capable, but he also loves the idea of being your dark knight in spiky armor. If you actually manage to take down a Foot soldier or outsmart one of the Turtles, Shredder beams with twisted pride.
“That’s my girl!” followed immediately by, “Now stand back while I finish this.”
You’re slowly (very slowly) making him slightly less genocidal. Not enough to stop hating the Turtles, but enough that he might spare certain civilians if you give him the big pleading eyes. He’ll never go full hero, but he’ll grumble and redirect his latest death ray if it means keeping you happy.
