I feel like since Roblox S has grown more and more within the last 5-6 months, there's been more requests to add people's OCs and what not. Some of those requests, weren't from people who were devs So first thing, if you want your OC in Roblox S you must be developer for Roblox S. There's few exceptions such as you've won an event, made fan-art and such, or just have an OC that'd be interesting to add Second. Make the OC relatively normal. Don't make the type of OC where "Oh! They always win this and that, they never lose" or "Hey, my OC has this ability and that ability! They're so overpowered and cool!!!" Make things relatively normal for everyone else Another thing, you can have as many OCs as you want, but don't excessively make 15 OCs without thinking each one through, make their lore somewhat contribute to the story/world and if you can't do that, try to make a mascot somehow One MORE thing is designing and this is somewhat complicated so I understand if some things didn't make sense before this. When designing an OC, there's a certain style that I'd like Roblox S to go off of. If that OC doesn't go off that specific design I'll most likely redesign it to make it match. If you'd expect your character's items to appear in-game or would like to wear their avatar, they'd have to lose sleeves if you had planned to add them, otherwise they're considered more of a mascot than anything. To make this part easier, try using items already in the Roblox S Catalog or ask me/@RobIox_S to check a certain item on the actual Roblox's list of accessories. Final thing is, they can make their own contributions to the world (such as factions, stores, etc.) as long as it can be easily programmed in-game. If it'll take next level coding, we likely can't accept that. Also, if you make an OC and aren't necessarily apart of the dev team, tell me or @Ah-Jay_11 about it or else it isn't canon I hope this helps people who are interested in making OCs for Roblox S! If there's anything else you're not sure on just ask me and I'll help
