Homnibus is a kindly old wizard or enchanter who first appeared in 1955 in the Johan and Peewit comic story The Moonstone. He appeared in several subsequent adventures, most notably the "non-canonical" Smurf story "The Smurfs And The Magic Flute". He also appeared in various episodes of the Smurfs cartoon show until Season 8.
He is a friend of Papa Smurf's who often visits him in order to play chess or work on issues relating to magic. He even gave his pet dog Puppy (formerly called Homni-One) to the Smurfs as a pet. He also assists Sir Johan and Peewit in their adventures. In "The Smurfs And The Magic Flute", he transported the two humans to the outskirts of the Smurf Village by using "hypno-kinesis".
In the cartoon show, Homnibus is friends with the bickering sorcerer couple Selwyn and Tallulah and was invited along with Papa Smurf to attend their 200th wedding anniversary. He has also adopted a young child and street urchin whom he named Justin in order to turn him away from a life of crime. In the comic books, he has a young male servant by the name of Oliver who made occasional appearances.
His character in the cartoon show was voiced by Jack Angel.
