All these AUs were created by multiple different people on Tumblr, some of them you can find as a Tumblr post screenshot on Pinterest. Just recapping the many types of Soulmate AUs out there! Feel free to use any of them!
Sidenote: How I title these AUs are gonna suck. You have been warned.
Timer Soulmate AU! Where there’s a timer on your wrists that counts down to when you meet your soulmate.
First Words Soulmate AU! Where you know the very first words your soulmate will ever say to you or what you’ll first hear them say when you meet. Alternative: Same thing but you know the words once you turn 18.
Last Words AU! Where you know the last words your soulmate will ever say to you. You don’t know you met them till you lose them.
Age Soulmate AU! Where you stop aging at 18 till you meet your soulmate.
First Touch Soulmate AU! Where there’s a black stain where you and your soulmate should make first contact. Like someone has a black stain over their knuckles. That means they’re going to punch their soulmate (probably at least) upon first meeting and contact.
Writing Soulmate AU! When you write on your skin the same mark appears on the same place as your soulmates. Such as if you doodle on your skin your soulmates gets those doodles on their skin.
Your Name Soulmate AU! Where you have your soulmates name on your wrist. First or last name (up to you). Alternative: Name appears once you’re 18. Alternative: It’s your enemies name on your wrist. Alternative: Both your soulmates name and enemies name, you don’t know which is which.
Other Half Soulmate AU! At birth you are given a necklace that is the missing half of your soulmate’s necklace.
Colour Blind Soulmate AU! Where you’re completely colour blind till you meet your soulmate Optional: Things go back to black and white when they die. Optional: Except of when you meet your soulmate its when you and your soulmate first touch.
Sharing Pain Soulmate AU! Where bruises, cuts, blisters, and such appear on your skin if your soulmate gets them and visa versa. Like if you get a paper cut your soulmate gets the same cut. Optional: You don’t feel the pain of it. Or you do feel the pain of it and can help treat the wound so your soulmate is okay.
Hues Of Hair Soulmate AU! Where you have a strip of your soulmates hair colour on your wrist and when they dye their hair it changes.
Colour Of Your Eye Soulmate AU! Where you only see in the colour of your soulmates eyes, you can’t see other colours till you meet them. Like if your soulmate has blue eyes you can only see blue till you meet them. Alternatively: You can’t see the colour of your soulmates eyes. Not until you lock eyes with them and see a whole new colour in them.
Light Of The Heart Soulmate
AU! Where the center of your chest glows when you and your soulmate meet. Ex: That one comic that has the nerd in the jock that’s connected to the original post. Find it on pinterest if not on tumblr.
Fear In My Soul Soulmate
AU! Where you feel when your soulmate is about to die and can help prevent it. Like you feel a pain in your soul when they’re in trouble.
Heterochromia
Soulmate
AU! Where you have one eye that’s your your eye colour and the other has your soulmates eye colour. When you meet and make eye contact, your eyes switch back to their original owner.
Mark We Share Soulmate AU! Where you and your soulmate have identical marks that match each other. Like you have the mark of a cat curled up in a ball, your soulmate has the exact same cat. Optional: When you and your soulmate make physical contact, the mark moves to meet each other. For example your soulmate touches your hand, both of your cats rush up to meet each other. (This one came from @gallopingmonroe-blog)
Red Thread Of Fate AU! You know the legend of the red thread of fate? That’s this AU. A red thread of string on your pinkey finger that connects you to your soulmate. The thread cannot be broken but it will stretch and tangle.
okay so you know the soulmate au where on your 21st birthday you wake up in your soulmate’s body? imagine if you were dating someone for a long time and on your birthday you wake up and you’re in their apartment so you’re like “yes it’s them!!!” and then you look in a mirror and you’re in the body of their roommate
Red tallies appear for every person you’ve loved, black for every person you’ve loved that has died, and a white tally for when you meet your soulmate
A mark that matches, sometimes like a puzzle piece to someone else, and grows hotter the closer they are to you
You have a tattoo of what your soulmate is most passionate about
You have a tattoo of the first words they say to you
You have a tattoo of how old you both are when you meet
Changing tattoo that tells you the coordinates of where your soulmate is
Tree tattoo that changes with the seasons, but blooms pink in spring instead of white if you met your soulmate
Identical tattoos or birthmarks
Incomplete tattoos that complete themselves on your skin when you meet the person with the rest of your tattoo
Tattoos that change colour depending on what your soulmate is feeling
Eyes
Heterochromia – you have one eye of your soulmates eye colour and when you meet you get your own eye colour instead of having two different eye colours.
You only see in black and white until you meet your soulmate
Reverse black and white where you give up seeing colour when you meet your soulmate
You only see in black and white until you touch your soulmate
You only see in the different shades of your soulmates eye colour until you meet them
You can’t see the colour of your soulmates eye colour until you meet them
You see colour the first time you hear your soulmates voice directly and the colour spills from their lips
Ears
You can hear your soulmates voice in your head, but only when they sing
The secondary voice in your head is your soulmate speaking
You can speak once you meet your soulmate
You can hear once you meet your soulmate (the first thing you hear is their voice)
Time & Age
When you reach 18 you stop aging until you meet your soulmate
Watch countdown to when you’ll meet your soulmate
Reverse countdown, your clock counts up and freezes when you meet
You have a clock on your body that tells you what time it is where your soulmate is, it changes colour when they get closer to you
Body or Hair
At new years on midnight for a single minute you possess your soulmates body
Your chest glows when you look them in the eyes
Marks on your soulmate appear on your own body
You have your soulmate’s hair colour on a stripe at your wrist, when they dye or chance their hair colour the stripe changes
If you change your hair colour, your soulmates changes to the same colour (your hair goes to it’s natural colour when your soulmates does)
When you change your hair colour, your soulmates eyes change to that colour
You and your soulmate share all physical senses (I.E pain, heat, pleasure, etc…)
Other
Red sting to connect soulmates
Your soulmate is the only person you remember from your past life
Everyone is given a journal that they can use to write to their soulmate
When you sleep, if your soulmate is awake you can see what they’re doing
You dream your soulmate, but very basically (such as their silhouette or the view of their back)
Telepathy soulmates
Sharing skills and talents with your soulmate
When your soulmate eats something you crave what they’re eating
When your soulmate cries you cry
When you kiss your soulmate for the first time your entire body glows
I got a lot of ideas from this post so I recommend you check that one out too!
