Mammon/Relationships

Lucifer Morningstar
Mammon claims that he is friends with Lucifer. It is currently unknown whether or not Lucifer is aware of Mammon's self-proclamation of their "friendship" or affirms it. In "Loo Loo Land", it is suggested that the eponymous theme park, which Mammon owns, is mostly a rip off of a larger amusement park owned by Lucifer.

Asmodeus
In "MAMMON'S MAGNIFICENT MUSICAL MID-SEASON SPECIAL (ft Fizzarolli)", it is shown that Asmodeus does not take kindly to him and how Fizzarolli forces himself to be a perfectionist for him. Asmodeus describes Mammon as a "selfish, manipulative, piece of shit".

It is also apparent that he doesn't have a good relationship with Asmodeus, as he sees him as an embarrassment because he loves Fizzarolli, but was caught off guard when, instead of laughing at him, people texted and gossiped at how they knew about their relationship all along, but Mammon promised that Asmodeus would regret admitting it.

Aside from their personal relationship, Mammon also has a professional one with Asmodeus, as Asmodeus admitted that he is the one who designs and manufactures the sex robots in Fizzarolli's likeness for Mammon to then sell for profit.

As stated by Asmodeus, he's known Mammon since "the start of Hell", implying their long history and relationship. Due to this, Asmodeus also has a personal nickname for Mammon, "Mam".

Fizzarolli
Until the events in "MAMMON'S MAGNIFICENT MUSICAL MID-SEASON SPECIAL (ft Fizzarolli)", Fizzarolli was "favored" by Mammon, being Greed's brand star for multiple uses. Mammon has sold multiple Robo Fizzes by his name, and never hesitates to gaslight him into performing past his limits.

Despite his insatiable love of money, some small part of Mammon genuinely comes to see Fizzarolli as a surrogate son. When Fizz begins to crack under the pressure, Mammon allows him to take a break, but only so he can get his act together and perform properly. However, when Mammon learns that "2 Minutes Notice" is all about him, their partnership immediately crumbles.

Blitzo
Unlike Fizzarolli, Blitzo saw through Mammon's act early on and isn't afraid to call out his flaws to his face. When Blitzo chewed him out for how he treats Fizzarolli, Mammon was not happy with his employee bringing acquaintances to the pageant. Mammon called Blitzo a "dumpster diver" due to him being a low-class imp, showing that Mammon has a mutual dislike for Blitzo. Маммон/Взаимоотношения
