Platinum Sperm

Pull out your Ultimate Hellfire Burst Wave Motion Cannon if you wish. In that same instant, I shall send your head flying.

Platinum Sperm (白金 精子, Puratinamu Seishi; Viz: Platinum Spermatozoon) is the ultimate fusion of Black Sperm, and a member of the Monster Association.

Appearance
Platinum Sperm is a very large and muscular humanoid, yet with a much more lean body than Golden Sperm. His signature head shape is much longer than the regular Black Sperm clones. His signature element is his platinum shimmer, similar to Golden Sperm's golden color. The platinum shimmer extends over the top half of Platinum Sperm's face, similar to a mask, and there appear to be two dark lines that trail down either side of Platinum Sperm's head and over the shoulders before tapering off at the pectorals.

Personality
Platinum Sperm is shown to be an extremely confident individual, so much so that he is confident enough in stepping up to King without any signs of anxiety and claiming that he can send the hero's head flying in an instant. He is also very vain, describing himself as perfect and flawless.

Monster Association Arc
Having grown paranoid and fearful of King's words and next movements, believing that the hero is looking down on him, Black Sperm is enraged and decides to merge all of his clones together in order to defeat King. All of the Black Sperm clones charge toward Golden Sperm and begin merging with him, while a unit of 100 Black Sperm cells is detached as insurance. Platinum Sperm is then born. Right after birth, Platinum Sperm readies to face King, showing no signs of fear. After King unfolds his arms and seemingly prepares for his attack, Platinum Sperm stretches the tentacle on his head and incapacitates several heroes around King with it, which frightens him. He then states that he realizes King has desired to fight him in his perfect condition as the reason why he has not made his move yet. Platinum Sperm proceeds to challenge King, telling him to unleash his Ultimate Hellfire Burst Wave Motion Cannon attack while claiming that he himself will finish the hero by sending his head off at the same moment. As King is closing his eyes and shouting the name of his attack in an attempt to intimidate him, Garou dashes in the direction of Platinum Sperm and sends him flying with a single punch before proceeding to splash Evil Natural Water with multiple blows in extreme quick succession.

Abilities and Powers
As a fusion comprising 53 trillion 999 billion 999 million 999 thousand 900 cells, including Golden Sperm, Platinum Sperm is an extremely powerful being. He possesses an overwhelming aura as sensed by Atomic Samurai. Platinum Sperm was also confident enough in his strength to challenge King, who is regarded as one of the most powerful heroes in the world and is even titled "The Strongest Man on Earth", without showing visible signs of anxiety.

Physical Abilities
Immense Strength: As the ultimate fusion of Black Sperm, a Dragon-level threat, Platinum Sperm is incredibly powerful. Using only the tentacle on his head, he was able to seriously injure and incapacitate multiple heroes, including S-Class ones.

Immense Speed: Platinum Sperm possesses an astounding level of speed. He was capable of repelling multiple heroes around him, including S-Class ones, in the blink of an eye using his tentacle without most of them being able to properly react.

Elastic Tentacle: Platinum Sperm can extend the tentacle on his head to great lengths and use it as a whip. He was able to attack his opponents with his tentacle despite seemingly being tens of meters away from them.
