Otherhand is the writer of the storyline of mother cognitive dissonance (not to be confused with Shigesato Itoi, the writer of the Mother storyline). He dosen't have an offical cameo, but he can be found if you load a save in a room only in the old vertion, or if you talk to a certian red mook on the concert grounds. He usualy appears in the form of a Mr. Saturn, with exception for the prevous stated red mook and if you lod a old save in the room that you fight larice in on mars.
