Procedumons are a species of Sisibi Monster with a unique ability: they come in thousands of variations, each with their own unique elemental abilities and quirks.
Procedumons are generated from a large, mysterious stone located in a neutral territory on Sisibi. Whenever a Sisiban touches this artifact, a new Procedumon is spawned, with its own unique appearance, powers, and personality. These are living, sentient creatures, and are capable of forming bonds as any Sisibi Monster can.
It is unknown if there is an upper limit to how many Prodecumons can be generated. So far, the largely-unknown location of the stone has kept generation to a minimum - but if an unscrupulous Sisiban were to find it, the world may be flooded with Procedumons.
