Golden Sperm

You have lost your will to fight over such meager damage... So you turn your back on the enemy to flee in tears? And you call yourself an S-Class hero?

Golden Sperm (黄金精子, Ōgon Seishi; Viz: Golden Spermatozoon) is a powerful fusion of Black Sperm's cells and a member of the Monster Association.

Golden Sperm is later defeated and killed by Garou.

Appearance
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.

Personality
Golden Sperm retains the arrogance that 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, agreeing with Homeless Emperor when the villain suggested leaving Fuhrer Ugly alive to further their own pursuits.

The new fusion was quickly shown to have little interest in the livelihoods of the other Black Sperm cells, and even suggested absorbing them as they had become obsolete.

Monster Association Arc
Upon being angered by Fuhrer Ugly's behavior and realizing that the heroes are largely distracted and weakened, Black Sperm merges a large number of his cells into Golden Sperm, who then attacks the fat monster for "crossing the line." Fuhrer Ugly attempts to fight back against Golden Sperm, but his acidic vomit is unable to harm the latter, who cites the anti-corrosive properties of gold as the reason why he is completely unfazed. Golden Sperm later witnesses Homeless Emperor appear and punish Fuhrer Ugly, who then leaves them out of their mercy.

Shortly later, Golden Sperm switches his focus on Superalloy Darkshine, who is trembling in fear due to suffering damage from Fuhrer Ugly's digestive fluids before. Golden Sperm comments about Darkshine's unworthiness for being an S-Class hero shortly before landing a punch on his face, which sends the hero flying a considerable distance towards Iaian, Atomic Samurai and Spring Mustachio's whereabouts.

While the 100 cells of Black Sperm hold Tareo, the remaining 10 trillion cells combine into one superpowered body called Golden Sperm. Tatsumaki is unimpressed, but Golden Sperm surprises her with his lightning speed and quickly beats her with multiple direct blows. The 100 cell Black Sperm is amazed by Golden Sperm's strength, who tells him that he might as well absorb him too, but Black Sperm refuses. Golden Sperm is then attacked by Tatsumaki again, trying to break his neck with her psychic powers to no avail.

King suddenly reappears, calling out his Hellfire Burst Wave Motion Cannon, and catches Black Sperm by surprise. However, the attack never comes, much to his relief, and he watches in confusion as King turns and runs away. He discusses chasing him with Golden Sperm, but Golden Sperm tells him they need to stay with the hostage, Tareo. The 100 cell body doesn't respond, having been cut in half as Garou emerges from the other side. Golden Sperm is surprised that Garou is still alive, and receives a brutal blow to the face. Black Sperm's remaining cells attack Garou, though he quickly wipes them out in an instant. The single remaining cell considers hiding, while Golden Sperm grows excited and moves to challenge Garou. He engages Garou, the two moving at blistering speeds that the heroes' eyes can't even keep up with. When the dust settles Golden Sperm lays dead on the ground, with Garou victorious.

Abilities and Powers
As a fusion of a mass number of cells of Black Sperm, a Mysterious Being that was already classified as a Dragon-level threat, Golden Sperm is extremely powerful. He possesses an extreme amount of raw power and speed, as demonstrated when he was capable of effortlessly defeating powerful individuals such as Fuhrer Ugly and Superalloy Darkshine. Furthermore, it has been stated by Murata that he did not know who is stronger between Golden Sperm and Orochi, although did clarify that the Monster King is a more advanced combatant and has better techniques while Golden Sperm is all about speed and power.

The fusion is comprised of 12 trillion separate cells merged together, while in the original webcomic, it is 10 trillion ones.

Sweet Mask stated that even if all of the S-Class heroes fought Golden Sperm, it would still be a very difficult task to defeat him. He easily defeated a weakened Tatsumaki and moved so fast that the present heroes could not even see him in motion. Along with this, he was the only one besides Saitama who was able to fight against evolved Garou on equal footing, even if it was only for a few moments.

Physical Abilities
Immense Strength: Golden Sperm possesses top tier physical strength; far surpassing the capabilities of his individual cells. He was easily able to brutalize Vomited Fuhrer Ugly, a powerful Dragon-level threat. Furthermore, Golden Sperm's strength is so overwhelming that he was capable of knocking out Superalloy Darkshine, a very powerful S-Class hero, and sending him a fair distance away, with only a single punch.

Acid Resistance: Due to having the anti-corrosive properties of gold, Golden Sperm is extremely resistant to acid. He remained completely unfazed when Fuhrer Ugly unleashed a blast of acidic vomit directly in his face, which did no damage whatsoever (where it had previously melted straight through Darkshine's skin). Immense Durability: Along with his immense strength, Golden Sperm also possesses amazing toughness. He was capable of taking slashes from Atomic Samurai, who was using the legendary Sun Blade to attack him, although the swordsman did manage to slightly penetrate his arm and even cut it off soon afterwards.

Immense Speed and Reflexes: Golden Sperm is amazingly fast, as demonstrated when he was easily able to punch Fuhrer Ugly faster than the monster could react. Furthermore, he is even fast enough to quickly appear in front of Homeless Emperor to defend the latter from Atomic Samurai, despite the extreme close proximity between them.

Absorption: Although Golden Sperm loses the ability to split his cells after the fusion is completed, he can seemingly absorb more cells into his body afterward, as he threatened to do to the remaining 100 Black Sperm cells.

Psychic Resistance: Golden Sperm is able to very effectively resist an injured Tatsumaki's psychic attacks with apparent very little effort. However, it has been confirmed that if she was in perfect condition, he could lose.

Fighting Style
Hand-to-Hand Combatant: Golden Sperm primarily relies on his brute strength, preferring to throw simple but powerful punches.
