Some or all of the canon Undertale characters swap roles and/or personalities with the other canon Undertale characters. e.g: Sans replaces Toriel. No new characters are added, and the story is relatively the same for the most part.

If only one character pairing is swapped, it doesn't fit in this type. In that case, the AU is most likely in the Character-centered type.
