This version of Papa Smurf is briefly seen by Traveler Smurf in the timeline he visited where "the Blue Plague" struck the Smurfs in the EMPATH: The Luckiest Smurf story series. Not much is known about this version of the character, but apparently he was one of the victims of the plague and was most likely responsible for sealing off the village from the rest of the forest by a magical force field to keep other Smurfs from being infected.
This version of the character is loosely based on the one from The Raven Child's Smurfette Village fanfiction series.
