==Summary==
 is a monster who first appeared during the S-Class Heroes' raid of the Monster Association.
Despite his dull appearance and small stature, he is one of the Association's most powerful members and is easily a high-end Dragon level threat capable of defeating even S-Class Heroes. He first appears when Tareo is separated from Garou, chasing after and tormenting the child. Atomic Samurai steps in but is soon overwhelmed due to Black Sperm's ability to split into numerous versions of himself, as well as reform whenever one of his selves is killed.

*Multiple Selves (Type 1 - Stated to have a countless number of "me" inside his body. Can argue and disagree with himselfOne-Punch Man: Chapter 106 - Terrible Multiplying Bastard, pg. 29One-Punch Man: Chapter 146 - Backup, pg. 9 & 10, meaning that every individual cell has their own mind and thoughts)
*Immortality (Type 3 - As long as he has remaining cell stock)
*Acrobatics (Atomic Samurai described him as nimble. Able to jump several meters into the air and perform flips to dodgeOne-Punch Man: Chapter 105 - AuthenticityOne-Punch Man: Chapter 152 - Check. When in coordination with other Black Sperm cells they can form a vortex around a target to never stop attackingOne-Punch Man: Chapter 146 - Backup)

*Size Manipulation, Elasticity, Body Control, and Duplication with Shapeshifting (Black Sperm is able to manipulate and enlarge his body in numerous ways. Whenever a Black Sperm cell is split apart, the pieces that are sliced off become a new Black Sperm. He can also just duplicate at willBlack Sperm's duplication and shapeshifting also works as a sort of pseudo-regeneration allowing him to recover from even being sliced into tiny bits as long as he still has sufficient cells in stock)
*Danmaku (A large amount of his duplicates should allow him to have this ability)

Attack Potency: Varies (The power of a Black Sperm body depends on its cell count) from Below Average Human level (A single Black Sperm cell is so weak that even a puppy could defeat itOne-Punch Man: Chapter 171 - The Last Guy I Wanna Run Into) to Large Town level (Ripped Genos' arm offOne-Punch Man: Chapter 148 - The Line. Psykos implied that Black Sperm and Homeless Emperor could defeat TatsumakiOne-Punch Man: Chapter 123 - Real Form, even after she had effortlesslyOne-Punch Man: Chapter 111 - Powerful Enemy overpowered Gyoro GyoroOne-Punch Man: Chapter 113 - Fake) | At least Mountain level (Far stronger than before. Knocked out Superalloy Darkshine and sent him flying away with a single punchOne-Punch Man: Chapter 149 - Ambush. Stomped Vomited Fuhrer Ugly) | At least Mountain level (Stronger than his Golden Sperm form, as he contains trillions of more cells inside his body. Fought with Flashy Flash and Post-Darkshine GarouOne-Punch Man: Chapter 155 - Results. Later fought Garou on his own for a while before being overpoweredOne-Punch Man: Chapter 156 - Divine Retribution)
Speed: Unknown, possibly Massively Hypersonic+ (Psykos believed that Black Sperm could fight with Tatsumaki alongside Homeless Emperor right after witnessing her defeat Gyoro Gyoro) | At least Massively Hypersonic+ (Faster than before. Intercepted an attack from Atomic Samurai with the Sun Blade. Casually blitzed Darkshine and Vomited Fuhrer Ugly) | FTL (Surpassed Flashy Flash's speed. Created a massive constellation with his sheer speed in 1.3 milliseconds alongside Garou)
Lifting Strength: Varies, up to Class G (Easily restrained Sweet Mask. Able to rip Genos' arm off) | At least Class G (Much stronger than Superalloy Darkshine, even calling him far too weak) | At least Class G (Significantly stronger than before)
Striking Strength: Varies from Below Average Human level (Comparable to its attack potency) to Mountain level (Ripped Genos' arm off) | At least Mountain level (Comparable to his attack potency. One-shot Superalloy Darkshine) | At least Mountain level (Comparable to Post-Darkshine Garou)
Durability: Unknown | At least Mountain level, likely higher (Withstood numerous cuts from Atomic Samurai's Sun Blade, but was also shown to be directly cut and lose his arm to the Sun BladeOne-Punch Man: Chapter 151 - The Greatest Obstacle) | At least Mountain level (More durable than its Golden Sperm form. Took hits from Post-Darkshine Garou and survived his Monster Calamity God Slayer Fist)
Stamina: Superhuman (Never seemed to tire during his battle against the S-Class Heroes despite taking an enormous amount of damage continuously)
Range: Varies from Below Standard Melee Range up to Several Meters with Size Manipulation and Elasticity. Tens of Kilometers with Sperm Tsunami (Implied to be able to flatten Z-City overtime if he decided to split to his limit and crush everything on his path) | Extended Melee Range by sheer size | Extended Melee Range by sheer size, Several Meters with Elastic Tentacle (Able to extend the tentacle on his head to strike opponents or restraint them)
Standard Equipment: None notable
Intelligence: Above Average (While he initially appears rather single-minded and straightforward, he is incredibly sharp in combat and was one of the few monsters in the Association to use tactics and outmaneuver his foes)
Weaknesses: If his cell stock gets low, he'll become weaker and eventually be unable to regenerate or make copies. Beating his bodies to death instead of slicing them will slow down his duplication. Complete body destruction will effectively kill a Black Sperm body and stop his duplication. If he fuses his cell stock permanently in a new body, he no longer can regenerate or duplicate with that body.

*Clones: Black Sperm is composed of fifty-four trillion copies of himself, essentially allowing him an absurd number of extra lives. He can split into any number of clones that he chooses, as long as he has enough cell stock.
*Shapeshifting: Black Sperm has demonstrated the ability to mold his body into whatever he so chooses. Against Atomic Samurai, he turned his body into a giant fist and attempted to smash him. Later, Black Sperm showed the ability to become enormous, as well as elongate his limbs.
*Regeneration: Black Sperm possesses a unique regenerative ability; as his body is formed from vast numbers of copies of himself working together, any damage he sustains will reduce his total count but his body is able to fully regenerate so long as he has reserves. Even if he is cut to pieces, his severed body parts will reform into more copies of himself.
*Replication: Instead of being killed, whenever he is dealt a fatal blow that would typically result in death, Black Sperm will split into even more copies of himself if he still has enough cell stock. He can also split himself at will. However, he is still susceptible to attacks that do not immediately cut him to pieces, such as blunt force or acid attacks.
*: Black Sperm rapidly splits up to overwhelm and crush his opponents.
* Black Sperm irreversibly merges his cells to form a more powerful version of himself.
*: Platinum Sperm rotates his arms and his tentacle to deflect attacks, allowing him to ward off punches from Flashy Flash
