Fizzarolli/Relationships

Blitzo
It is implied that at some point early in his life, Fizzarolli was on fairly good terms with Blitzo and they were quite possibly friends, however, by the start of the series, their relationship would turn into an antagonistic one. While it is currently unknown what the circumstances were that led to their falling out, it is shown that Blitzo was nervous when encountering Fizzarolli again and became uncomfortable when he mocked him during the episode Ozzie's, commenting on how his 'love life is a pile of shit.'. When Blitzo was scrolling through his photo gallery at the end of the episode, however, it is revealed that Blitzo and Fizzarolli knew each other when they were younger and spent their childhood together.

Moxxie
Although the two don’t really interact that much, Fizzarolli isn’t a huge fan of his lovey-dovey relationship with Millie and he mocks him for it.

Millie
Fizzarolli and Millie have yet to properly interact on the show, but she stomps on him so Moxxie can continue singing.

Asmodeus
Fizzarolli and Asmodeus appear to have some sort of a romantic relationship, as shown in the episode Ozzie's.
