Seth embodies chaos and destruction, aligning with his mythological origins. He relentlessly targets his eternal rival Horus through disruptive behavior, driving their antagonistic relationship with pranks and schemes. One such plot sees Seth adopt the Phantom Thief persona to steal the Eye of Medjed, a precious gem, forcing other deities to intervene. His actions consistently sow discord among the divine ensemble, underscoring his chaotic essence.

Seth explicitly despises eggs, creating a sharp contrast with Thoth's preference for them during their interactions. His personality radiates mischief and unpredictability, frequently manifesting in practical jokes and disruptive antics that sustain ongoing tension.
