Mammon is the embodiment of Greed
Seeing as Asmodeus is ruler of the Circle of Lust, so it makes sense that the other Seven Deadly Sins would have Anthropomorphic Personifications. While Mammon has not been physically seen, he seems to be an industrialist and capitalist, marketing things like cereal, soft drinks, and everything in Loo Loo Land. Fizzarolli literally sold his body (presumably for money) to Mammon in order to become the mascot of these products, and is now a cyborg as a result, something he seems just fine with. The designation of Embodiment of Greed could fit very well.
