OC DYNAMICS WEEK 2025

Want to explore your original characters’ dynamics and share them with other creatives? Or maybe you’re making new OCs and need ideas for their relationships to each other? Welcome to OC Dynamics Week!

OC Dynamics Week is an event taking place on August 18th - August 24th 2025. There is a prompt for each day of the week and three bonus prompts! Simply post your creation (any medium!) about your original characters using one of the given prompts. Fill one prompt or all of them, does not matter, just make something and have fun! Use the tag #ocdynamicsweek25 so that other participants and I can see it!

I will be reblogging your creations on this blog!

Rules:

Original characters only! Fandom OCs are fine, but the characters within the dynamic must be OCs.

Make something (writing, visual art, some other creation) with a given prompt, then post it on Tumblr during Oc Dynamics Week and use the hashtag #ocdynamicsweek25. Interpret the prompts freely and include as many OCs within the dynamic as you wish!

There are no strict rules for what content is allowed. However, I may choose not to reblog something if I feel that it goes against the spirit of the event (AI generated content, hateful content etc).

Event is over but you still want to do the prompts? No worries, keep working on the daily prompts or fill the bonus prompts if you wish! I'll keep reblogging posts for a while after the event is over.

Bonus rule: interact with at least one other creation for each piece you make yourself! Like, reblog, leave a reply, or even send the creator a message if you want - let’s spread the love! ♡

Prompts:

Day 1. roommates / competitive

Day 2. best friends / soft

Day 3. co-parents / awkward

Day 4. cousins / playful

Day 5. lovebirds / shy

Day 6. coworkers / curious

Day 7. distant relatives / difficult

Bonus prompts:

ex-friends / formal

strangers / suspicious

neighbors / vulnerable

Prompt guide

each prompt contains a type of relationship and an adjective. you can fill a day's prompt in one of 3 ways (using the first prompt as an example): 1. use only the type of relationship → make a piece about roommates, 2. use only the adjective → make a piece about ocs who have a competitive dynamic OR 3. use both → make a piece about roommates who have a competitive dynamic. 

only do the prompts you want to do! you can do the bonus prompts after the event if you want to keep going, or you can swap out one of the main prompts for a bonus prompt.

Asks are open in case you have any questions! Happy creating!♡
