Inspired by 20 Fun Things to do With Your OCs! by Stormyth on YouTube. These are things I am doing or plan to do with my characters. It also helps with theming and descriptors when I'm writing.
This is all for fun and geared a bit more towards writers than visual artists. I'm doing this with characters from my book Wings a Flutter which you can learn more about @wingsaflutter-author
LONG POST AHEAD. I couldn't use Read More because it broke the number order.
Flower Language
Exp | Celeste: Dried Orchids - admiration, beauty, and sophistication + rare and enduring love
Crystal/gem meanings
Exp | Bailey: Amethyst - Peace, intuition, and clarity
Scent Profile (Perfume/Candle)
Your elemental power is greeen...or strawberry or patchouli, perhaps amber and sugar crystals
Build a Pokémon Team
I believe there are over 1,000 pocket monsters each with their own unique skills and aesthetics. Which six best fit your OC?
Draw/Write in Different Styles
It's good practice for visual artists to understand shape language and color theory. When it comes to writers, it can help your characters' personality be more unique if you lean into Shakespeare for some and Tomi Adeyemi for others.
Suggestions for visual: Winx, FNAF, Poppy Playtime, Strawberry Shortcake. Danny Phantom, Spongebob, Hazbin Hotel/Helluva Boss, Sanrio, Pucca, Monster High
Write Your Own Fanfic
If you're not already, this is a good way to get out ideas that don't work in canon (due to story line, it being too ooc, etc) but you still want to explore.
Make an Animal Companion
Turn your OC into an companion or make an animal to be their companion.
Role/Personality Swap
Based on Glee: S3 Ep20 “Props”, but it has been done MANY times in media. Swap heroes with villains to see how similar or different they really are.
Do a High School!AU
If you're writing adults, it can be fun to imagine what they would look like when they were even more immature than they are now. If your high school has uniforms, how would the character try to skirt around the rules to customize their look? Would they even try?
Plan a Collab
Possible brands include: Build a Bear, Bath & Body Works, Dunkin’ Donuts, Crubl Cookies, any fast food place, Squishmallow, Squishable, Selkie, etc.
Make a Coloring Book
What scenes would you like to come to life? Draw or sketch them out, or find others' pages that look similar to your imagination. Don't forget to give proper credit to original artists if you choose to post it somewhere!
Design Merch
Did somebody say Marketable PlushieTM? For artists, it's a lesson or quiz on how to simplify a design. For writers, it can help you pay more attention to details even with the most mundane objects. Kind of a part 2 to Number 10
Design a Logo/Signature
How would your OC write their name? Sloppy vs thoughtful writing. A visual thought exercise.
What fruit is your OC?
This can kind of go with Number 3, but this one is more about taste and texture. This is a fun research rabbit hole to go down if you're feeling stuck.
Design a nail set based on your OC.
Or just find nail sets that are already made that reflect your OCs if you don't wanna do all the detail work.
Give them powers or take them away (Same universe)
How would your OC change if they received the magic/ability to save a person they lost or get revenge? What if they lost the only thing that made them special?
Make a Playlist pt2
This is just adding on to what Stormy's video suggested. I think it'd be fun if you made a playlist from the POV of an OC making it for another character. Option 2: A ship playlist. Extra challenge: Using only a single genre, especially one you're unfamiliar with could lead to new discoveries.
Make a Tarot/Oracle Card
Depict couples as The Lovers, of the resident introvert as The Hermit. Maybe make your own deck completely from scratch!
Compare Heights
I tend to use Hikaku . It's just fun to see the variety and helps with writing movement and interactions.
Create an in-universe Guide.
I've done this with Wings a Flutter in Canva. It's also sort of the whole purpose of my authorial blog.
