Atomic Samurai vs. Black Sperm

Atomic Samurai vs. Black Sperm is the battle between the S-class hero, Atomic Samurai, and the executive of the Monster Association, Black Sperm.

Prelude
Tareo is running in terror from Black Sperm, who found the child and is catching up to him. The monster tells the child that he's not going to do much to him except kill him, explaining that it will be rather painless and over in an instant. Black Sperm senses an attack coming for him, and dodges the strike. That strike was from Atomic Samurai, who found Black Sperm while roaming through the Monster Association. The swordsman compliments Black Sperm's nimbleness, and their battle begins shortly after.

Battle
Atomic Samurai introduces himself as the hard boiled yet kind-hearted S-class hero. Black Sperm recognizes this name, although isn't impressed by the hero's appearance. Nevertheless, he says that he's been waiting for Atomic Samurai for a long time, while the hero states he has no business with Black Sperm. The monster feels enraged when he senses that Atomic Samurai is looking down on him, and transforms his body into a very large and muscular arm. Black Sperm asks Atomic Samurai if he's mocking him, which the hero confirms, going so far as to say this will be an easy win for him. Kamikaze unsheathes his sword and slices the monster's arm off, explaining to Black Sperm that he's fought countless battles against enlarging monsters and that he's used to it. To his surprise, the sliced arm transforms into another Black Sperm. Atomic Samurai notes that the replicating monsters such as Black Sperm are the most annoying type. Black Sperm mocks the hero's n

onchalant attitude, deriding his idiocy while knowing that Black Sperm can simply multiply whenever he pleases, and that no matter how many times he splits, twists or tears him apart, he will keep on multiplying. While he's talking, Black Sperm's head multiplies into several heads that expand sideways, and Atomic Samurai slices all of these heads in half. Kamikaze calls Black Sperm the true idiot, and believes all he has to do to win is shower Black Sperm and his copies with a countless number of slashes. Black Sperm goads the hero into giving it everything he's got, prompting the hero to slash Black Sperm into several hundred pieces. Unfortunately, all the chunks of flesh morph into more Black Sperms, which Atomic Samurai slashes again, and again, the chunks of flesh form into new Black Sperms.

The hero decides to unleash his Atomic Slash, slicing all of the Black Sperm copies into little pieces for a third time. All of the Black Sperm chunks combine into a large black wall with faces of Black Sperm surrounding Atomic Samurai, with the monster claiming that the battle is over, and that this will be his deathbed.
