Fizzarolli/Relationships

Blitzo
Due to some pictures saved on Blitzo's phone, it is implied that at some point early in life, Fizzarolli was on fairly good terms with Blitzo and they were quite possibly friends. However, they seemed to have had a falling out and Fizzarolli now views him in an unfavorable light. 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".

Moxxie
Although the two have not really interacted that much, Fizzarolli did make a passing comment about how Moxxie did not have any creative showmanship whatsoever when introducing him. He also was not a huge fan of the latter's romantic relationship with Millie, and he mocks him for it.

Millie
Fizzarolli and Millie have yet to properly interact on the show, but due to her striking him in the head with a guitar so Moxxie can continue singing, it is believed that he does not view her favorably either.

Asmodeus
Fizzarolli works at Asmodeus's club, as shown in the episode "Ozzie's". Fizzarolli appears to be valued enough to be allowed seating with Asmodeus at his private balcony. The two share a mutual disdain of sentimental relationships and, combined with their cruel senses of humor, they take part in mercilessly bullying others such as Moxxie for.

Furthermore, Asmodeus appears to have a close relationship with Fizzarolli, as he worriedly rushed to Fizzarolli after the latter was struck by Millie, and they can be seen hugging each other during Moxxie's love song.
