Zib (Royalty AU)

Inferiority Complex and Pathological Envy: His entire identity is built under the shadow of his twin brother, Dib. He harbors a deep resentment towards King Membrane for choosing Dib as the legitimate successor to the throne. This envy leads him to develop an obsession with taking everything his brother owns: his status, his crown, his father's love, and eventually, Zim.

Narcissism and Megalomania: He perceives himself as the only one worthy to rule, believing that his intellect and his mastery over dark magic make him superior to others. He demands absolute submission. He enjoys the power to control those around him, especially Zim, whom he magically binds with an obedience spell just to feed his own ego.

Machiavellianism and Impiety: His moral compass is completely broken; for Zib, the end always justifies the means. He has no remorse for betraying his own blood. Banishing Dib to the cursed mirror and faking his death in front of his father demonstrates a complete lack of empathy. He is extremely calculating, patient, and manipulative, capable of feigning the role of the "perfect and afflicted son" before the king while orchestrating the ruin of the kingdom behind his back.

Paranoia and Anxiety for Control: Despite his facade of confidence and arrogance, Zib lives with a constant fear of being discovered or losing control. This insecurity manifests itself in his need to monitor everything and in the "10-foot curse" he imposes on Zim: he cannot stand that the variables of his plan move away from his presence. His mental stability is fragile; when things don't go exactly as planned (like Gaz's intervention), his arrogance quickly turns into desperate anger and chaos.
