A black and white illustration of Gon Freecss from Hunter x Hunter, divided into two contrasting halves. On one side, Gon has his normal appearance, with a determined and intense gaze, spiky hair, and classic manga features. The other half is dark and chaotic, with thick shadows and organic shapes that seem to flow and spread across his face, representing a dark transformation. The eye on this half is white and expressionless, adding a sinister atmosphere. Manga style, with a strong contrast of light and shadow, symbolizing the duality between innocence and dark power.
