Blitzo/Relationships

Moxxie
Blitzo often degrades Moxxie as the butt of jokes among his employees. He hardly addresses Moxxie's concerns when they are not focused on his interests, mocks Moxxie's sex life, and has zero respect for Moxxie's privacy, going as far as to stalk Moxxie as he sleeps. Ironically, Blitzo insists that he considers them all to be family, though this was when he was defending Loona in the situation.

While in the pilot, Moxxie was shown to be agitated by Blitzo's behavior and would mostly scream whenever talking to him, the relationship went vice versa In "Murder Family", when Blitzo got annoyed and angry at Moxxie for making him miss his shot at Martha. After Moxxie saved him and Millie from Martha's wrath, Blitzo did accepted Moxxie's apology and hugged him, but not without warning Moxxie that if he ever pulled a stunt like that again Blitzo will hurt Moxxie and Millie.

Despite his mistreatment, Blitzo does seem to care for him, as he easily forgives Moxxie's naivety and celebrates his killing of Martha with a party. He also allows him and Millie to have fun in Loo Loo Land, reassuring them that he can keep watch over Stolas on his own.

Blitzo also has an obsession with Moxxie and his wife, as he keeps following them around outside work and even trespassed in their home to watch them sleep. This obsession seems to have a sexual side to it, as he made dolls resembling Moxxie and Millie, with whom he sexually fantasizes. This is also hinted by Blitzo's threat to Moxxie after Moxxie saved him from Martha.

Millie
Millie and Blitzo seem to have a positive relationship. Unlike her husband, Millie seems to agree with some of Blitzo's more "out there" ideas. However, Blitzo stalks both Millie and her husband and sexually fantasizes about them both. While Moxxie feels harassed, Millie, on the other hand, doesn't seem to care about his intrusions in their private lives and and laughs when she finds him in their fridge, not thinking it's a big deal.

Loona
Prior to the events of the pilot, Blitzo adopts Loona and hires her to be the company receptionist. He seems to see her as a daughter figure and congratulates her for the tiniest of successes, much to Moxxie's dismay. Blitzo disproportionately coddles her, covering up for her negligence and making up excuses for her sloppy work and disrespectful behavior. Even though Blitzo treats her like family, Loona does not reciprocate the feeling and expresses high animosity toward his affection, although Blitzo is oblivious to this. However, she does crack a small smile when he defends her and smiles once more as Blitzo brings them all in for a group hug.

His father
It is stated that Blitzo and his dad do not get along since his dad does not approve of his dreams of getting into musical theatre.

Tilla
Tilla is one of Blitzo's sisters. Aside from the fact that the two have worked together in the circus alongside their sister Barbie Wire as shown in one of the posters in Blitzo's office, it is unknown what relationship they have outside of being blood related as they have yet to interact in the show.

Stolas
Blitzo had a one-night stand with Stolas in order to borrow his grimoire for opening portals to Earth. Ever since then, Stolas has been sexually attracted to him, but the feeling is not mutual; Blitzo avoids him as much as possible, to no avail, as Stolas calls him rather often to order assassinations or simply to grab his attention. Once, while informing him about a potential target, Stolas begins to talk extremely dirty to Blitzo, causing the latter to destroy his cell phone and feed it to Loona. Despite his reluctance to treat with Stolas, he feels obliged to gratify his sexual desires, as his hitmen company stands solely on the fact they can use Stolas' grimoire to access the living world. In "Murder Family" he agrees to join Stolas for a monthly sexual encounter in order to keep the book but leaves the phone behind while Stolas continues to talk dirty. In "Loo Loo Land" he ends up smashing his phone by accident after talking with Stolas, likely being a reference to the pilot. It is also implied Stolas might have personally gone to his office several times, as one of the emergency buttons Blitzo has under his desk bears his name.

Eddie
After being insulted by Eddie, he was happy to find out that Eddie was the right target all along and immediately kills him in one shot as he and his employees proceed to disembody his carcass and return his deceased self to his mother back on Earth.

Robo Fizz
While working at Loo-Loo Land as a clown Blitzo apparently had a rivalry with Fizzarolli's robot doppelganger. Robo Fizz comments how the kids would run away from him and how the crowd would be silent when he would tell jokes. Blitzo attempts to shoot at the robot for his mockery, only for them to end up battling and wrecking if not destroying Loo Loo Land in the process. It is unclear to what extent this relationship has with the real Fizzarolli, but Blitzo's comments suggest he does not fancy the clown demon any more than Robo Fizz.
