Flanders is a minor Cartún in Sinsonismo. He is a recurring antagonist to Omersinso. Most sects hold him to represent a heretical strain of thought centered around ecstatic optimism and faithful quietism, one which represents the fallen world and its failed ideology. Omersinso rebukes him through action or dialogue, enforcing a more pragmatic approach to the world, in his typical manner of the holy clown archetype. In the most notable Episo of this type, Omersinso punishes Flanders by slaying his wife Mód.
Flanders is frequently depicted with a mustache, and wearing his Sunday best. Or sometimes, nothing at all. Nothing at all.
