Any ships (platnic and romantic) can be submitted.
Any type of fanwork material can be accepted i.e art, fanfiction, art and crafts creations, song playlists, video or picture edits, etc. You think of it? Try and do it! We'll love to see what you can come up with your skill and creativity.
Works that don't have ships (such as character study or general works) can be submitted for the event as well.
Any NSFW works including underage characters engaging in sexual acitivites themselves will be rejected. Metal Bat | Badd's age seems to be difficult to trace to a proper status of whether he's legal or not nominally (here's the post where we've discussed this). For creators event it is up to you if you want to include him at all though! In this event his birthday has taken place and he is 18 and able to to be portrayed/written wiht NSFW themes, so NSFW posts involving Metal Bat | Badd are eligible for submission!
Works with OCs or Reader as the main/secondary character will not be accepted. This has to be works where the main relationship or character is someone canonically from the manga or webcomic.
Anything made with AI/Generative Models (GM) is unacceptable and will be rejected. This event is meant to be an act of love for the community by celebrating the genuine love for the One Punch Man series shown through the unpaid labour of creating fanworks. Using AI/GMs to create fanworks undermines that genuine love by ignoring the time, effort and emotional connection it takes to create these pieces through personal capability alone, and AI/GM devalues whatever it makes compared to if a person made it themself because the novelty of a person creating that piece by their own ability never dies.
Subsequently any works submitted as real but later found to be made with AI/GMs will be removed swiftly, and for lack of clarity/deception will result to an immediate blocking from engaging with the rest of the event.
