Golden Sperm is a large and muscular humanoid that retains his previous self's head shape. His signature element is his overpowering golden shimmer which feeds directly into his many physical powers. Golden Sperm retains the arrogance that the deceased Black Sperm possesses, and has no issue looking down upon beings it views as inferior. He takes pleasure in using intimidation tactics and cruelty, but remains strategic in his thinking. As of November 2024, he made peace with Saitama and Tatsumaki, claiming that he had reflected deeply and decided to put an end to unnecessary and futile wars. He is the older brother of Platinum Sperm.
