The rule against passing someone else's work off as your own isn't just a wiki rule--it's a rule governing artistic and literary work in general. If you edit or recolor someone else's drawing, you must identify it as such, and you must identify the artist who originally made the drawing that you are editing/recoloring.

Even then, you must get permission. Editing/recoloring without permission is technically a copyright infringement. (People have been sued for less.) Under current copyright laws, most artistic and literary works are automatically copyrighted the moment they are produced.
