OC DYNAMICS MONTH 2026

Welcome all OC enthusiasts! This entire August 2026 will be all about your OCs, or more specifically, the dynamics between them. Post your writing, art, or whichever medium you choose on Tumblr with the hashtag #ocdynamicsmonth26 and make sure to show some love to other participants as well! Your posts will be reblogged to this blog.

My asks are open for any questions & comments you might have! Please read the rules and prompt guide first!♡

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 Month and use the hashtag #ocdynamicsmonth26. Interpret the prompts freely and include as many OCs within the dynamic as you wish!

You can post your work late, for example you can post your creation for Day 1 on Day 15 if you want! All I ask is that you don't post them early.

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). Including content warnings for heavy topics is encouraged!

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! ♡

Prompt guide

Each main 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 ex-friends, 2. use only the adjective → make a piece about ocs with a powerful dynamic OR 3. use both → make a piece about ex-friends who have a powerful dynamic.

This year, the bonus prompts are dialogue prompts. You can combine or swap them with main prompts or just do them in addition to the main prompts! You can use the exact wording, tweak it to fit your piece, or simply use the dialogue to inspire your work without using it directly.

Day 1 of @unwholesomeocweek: Violence/Hatefucking

(If u count getting ur leg humped by your boy best frenemy as ‘hatefucking’)

Ninjago Oc Secret Santa 2025

What is a Secret Santa?

A Secret Santa is a gift giving event; you’ll be assigned someone to secretly make a gift for, and someone will make a gift for you in turn.

It’s very important that your giftee doesn't know you are making them a gift and vice versa, that you don’t know who is making you a gift!

Are there any rules?

Absolutely no N/S/F/W or Suggestive content is permitted for prompts, gifts, or references. This is /not/ an 18+ event.

Blood and Injuries may be permitted at the giftee's decision.

No direct contact with the person you’re making a gift for; you can communicate through me or ask through anon on tumblr if you can.

No AI art/writing, Gacha edits, face claims, picrews, or bases will be permitted for oc reference submissions or gifts.

Oc x Canon and Oc x Oc ships are 100% allowed.

Fankids, sonas, and self inserts are also allowed; my only rule is that fankids of Lloyd x Canon ships are not permitted.

Respect requests regarding holiday or seasonal preferences when making a gift. Don’t depict an oc participating in a holiday or seasonal activity that the creator asked not be depicted.

You must draw the character(s) you were assigned and they must be visible (feel free to ask for clarification)

How many ocs can be submitted total?

At least one oc is required, but up to three can be submitted ^^

What will I need for sign ups?

Refs or art that show a clear, colored depiction of your oc.

OR at a piece of writing for said oc (does not need to be a whole fic. Could easily just be a quick blurb showing how they’re written as a character)

Basic Information/Fun Facts about your character. This can be background information, relationships, likes/dislikes, age and height, personality, etc.

Suggestions or prompts for your gift giver. Stuff to help get their brain going.

Your blog name (not the name you go by online but the url name. Like @/Ninjago-Oc-Appreciation. Make sure it’s a tumblr url, and not from any other social media)

What’s the general timeline for this event?

Sign ups will officially begin near the end of October, around the week of Halloween.

Assignments will be within the first couple of weeks of November.

You will have until December 23rd to January 7th to finish your piece. These will be the designated posting days.

January 8th to 14th will be the designated late week.

How do I sign up?

In Late October, I’ll post a google form where you can submit your oc(s)! There will be one for writing and one for art!

Please reach out to me in someway after signing up. This can be through messages, asks, comments, etc. In the past we’ve had issues with the forms, where they’d “eat’ a submission, and I’d like to know when to check to make sure this doesn’t happen again.

Additional Notes:

The event title, Secret Santa, is simply a reference to the holiday activity/a gimmick. It is not meant to restrict the event to only those that participate in Christmas, so feel free to join in regardless of what holidays you celebrate (or lack thereof).

Google forms does require an email in order to make submissions with images and documents, a necessary part of the sign up process. The process is entirely private on your end, so I will not be seeing the emails used.

If you cannot use google forms for whatever reason, please contact me. I'd be happy to work something out.

We’ll be using #NOSS2025 and #SecretNinja2025 as tags for this event!

That’s all! If you have any questions feel free to let me know, I tried to cover everything but I may have missed something!
