So I have an original character (no bull) I want to make in MUGEN. Can I use them again (like in an actual game) or will there be a problem?

Its yours no matter what you do to it, put it in deviantart in drawings or make it for mugen. If you are worried you can add a readme to it.

Just remember that someone might use your character and edit over it to make something else, that happens. Doesnt make your idea ny less your own.

If the original character is edited using an existing character sprite (for example, using a Ryu sprite as base), it may not be 100% original, and instead be considered a derivative work. Just to keep into consideration in case you want to profit or monetize it
