BIVE
Despite Bive's eccentricities, NULL doesn't dislike or harbor ill will towards her. In fact, Bive is one of the only NPCs he doesn't seem to have a problem with, none of his interactions with her suggest any type of dislike (outside of being glad it doesn't have a nose so it can't smell her). However, one of his interactions suggests that she will one day be kidnapped along with PartyNoob in order to please MR.
DrRETRO
Like some other NPCs, NULL refuses DrRetro's help, but solely because it believes that only he can complete his transformation into an individual and outside forces tampering with that would ruin its plans. DrRETRO harbors negative feelings towards it, saying that she hopes it "gets what it deserves" and refers to the entire helperbot hivemind as "diseases".
FLESHCOUSIN
Due to also being part of a hivemind, NULL sees some small amount of kinship with the FleshCousins. Despite this, it still believes itself to be superior,and wants to use the species for its master plan.
FOLLY
Despite being confidants, NULL and Folly don't get along well. Folly hates NULL's loyalty towards MR, as she sees her deal with it to be a means to an end, while NULL only wants her to follow orders and listen to their higher-up. It also looks up to her as a symbol of individuality, and wishes to hear her experiences with being her own person for its own prime. He even picks up on her way of speaking and acting to further emulate her.
GNARPY
NULL isn't outwardly aggressive with Gnarpy, but that's because he knows that that's what xey want. He knows that above all, xey crave attention, and Gnarpy themself hates being faced with this fact. It can be said that Gnarpy hates NULL, and would rather silence him than let it keep going on.
INFECTED
Similarly to how it treats Gnarpy, NULL has disdain towards Infected and brings up his insecurities and in a way insults their appearance and illness. Infected himself does have a past with helperbots, but hasn't used one since they began mobilizing for the prime. NULL is both envious of and glad it doesn't have individuality in the way Infected does, as her mind is corrupted and unstable and his body is sick.
LAMPERT
NULL hates Lampert. NULL hates that despite being an individual, Lampert spends most of his time not doing anything but standing unmoving inside of ROKEA for days on end with no goals or ambitions, it makes it sick. And yet, he also fills him with envy, for being enough of an individual to decide to do absolutely nothing. Despite NULL's hatred, Lampert has no feelings towards him. positive or negative.
MANNEQUIN_MARK
In NULL's perspective, Mark is what it wants to be. He escaped from her own hivemind and completely lives without it, and while this concept greatly intrigues it, it also cannot overlook how emotional and depressed Mark is without the other mannequins. NULL doesn't fully see this as a result of Mark's tumoltuous relationship with Wallter, but rather as a symptom of breaking free from the hivemind. Mark dislikes NULL, due to how much he hates remembering and talking about the other mannequins and their own personal issues.
MELANIE
Melanie wants to understand and help NULL leave MR and Folly behind, as she believes he can still be "saved" before it's too late. She thinks that he isn't inherently evil, and its goal of individualization might help it realize such. However, NULL doesn't want to listen to what she thinks, and believes that both of them being animals of prey means they're already resigned to serving others. He also believes that Melanie's death was essential in his goals with Folly and MR, and thinks she should've stayed dead.
MOZELLE
NULL believes that Mozelle is wasting her powers on kindness, and thinks that ruling Hell with an iron fist would be better suited for someone in her position. It doesn't like when she asks him simple commands, and thinks he's impolite and misses when helperbots actually helped people.
MR
Icarus himself. NULL takes on the name Daedalus around it, and it wishes only to serve Icarus and do what it wants. He is committed to helping MR re-ascend to godhood, being the one to soon "build [MR] new wings". NULL can be compared to the members of MR's cult, as his loyalty towards MR is nothing short of worship with how he talks about it in unrelated conversations and will stop at nothing to assist it in its goals. It believes that everyone, most especially Folly, should just listen to it and what it has to say, for only it has the answers to everything one needs to know, and only it is deserving of praise.
PARTYNOOB
NULL resents PartyNoob as even though they are the One (the perfect sacrifice for MR), they reject this position and escaped the cult before they could be sacrificed. NULL outwardly believes that PartyNoob is stupid, unaware, and undeserving of their status as the One, even saying that he hopes they die without being loved. He wants to understand exactly why they were chosen, as they aren't even aware of their status. PartyNoob never really understands what NULL is saying, so they're completely unaware of his hatred and instead sees it positively as they do almost everyone else.
PEST
Possibly the only NPC that hates NULL just as much as he hates them. In most of their interactions, they threaten each other with physical violence and karmic punishment. They are already opposed to each other due to their shared connection with Folly (extremely negative on Pest's side), and are only more averse to each other from NULL's status as a helperbot and Pest's hobby of taking robots apart for spare parts.
