Zebruh is a indigo blood living in a posh neighbourhood, enjoying a luxurious life in his giant mansion. Zebruh is a self-proclaimed lowblood ally, though it quickly becomes clear that he has very little regard for them. This is evident when the player notes that despite his claims of having lowblood guests, said lowbloods are actually slaves in his hive in all but name; dealing with all sorts of menial chores while being denied food and rest. His poor treatment of his guests have resulted in the lowbloods being weak and malnourished, though he feigns confusion when the player points out his guests' ill health. When attending a lowblood concert with the player, he neglects informing the other lowbloods of the fact that a culling is about to take place, claiming that helping them out would put him at risk. It should also be noted that he's a hypocrite; criticizing highbloods who use lowbloods for social advantages despite the fact that he's no better than they are. Overall, his thinly-veiled prejudice towards lowbloods is clear for all to see, and really couldn't care less about the welfare of lowbloods.

Apart from that, Zebruh seems to be quite desperate in terms of relationships, though he tries to be as smooth as possible while hitting on the player. Even though the player repeatedly states their desire to have friendship and nothing more, Zebruh routinely misinterprets the player's words for something else entirely. He sees friendship as a stepping stone for romance, not something entirely platonic. He asks about the player's quadrant situation numerous times, which then reveals that he wants the player in any one of his quadrants, as long as it gets filled. When the player angers him in one of the bad endings, he expresses his anger towards trolls (mostly lowbloods) that expect him to provide for them without getting any concupiscence (or any sort of romance) in return.

Zebruh is also shown to have a tendency of talking over other people or just turning a deaf ear to what has just been said. He repeatedly interrupts or talks over the player, denying the player a chance to speak. When he's not monopolizing the conversation, he would outright ignore what the player stated. This is best illustrated when he does the exact opposite of what the player requested, also highlighting the fact that he does not care about other people's preferences. He also conveniently pays no heed to the player's description of a non-romantic friendship, and completely disregards the player's attempt to explain themselves when a misunderstanding takes place.

While Zebruh is a snazzily dressed troll, this only reflects on his status as a highblood. As a indigo blood, Zebruh is fairly formal in speech and manner, though he's noted to be quite sleazy and does end up swearing when incensed. Unlike fellow indigoblood Equius, he does not express any discomfort over using crude language. He seems to be a litterbug, given the fact that food wrappers have been thoughtlessly discarded in his room.

I'd imagine him sounding like Walter White from Breaking Bad.
