Genos vs. Carnage Kabuto

Genos vs. Carnage Kabuto is the battle between S-Class hero, Genos, and the House of Evolution's Dragon-level monster and most powerful warrior, Carnage Kabuto.

Prelude
Genos and Saitama arrive at the House of Evolution only for the former to swiftly destroy the building with a massive blast.

Saitama finds a basement in which they both enter. In the basement, one of Dr. Genus's clones is killed by a chained up Carnage Kabuto. The real Dr. Genus converses with Carnage Kabuto and asks if he could kill Saitama and Genos for him. Carnage Kabuto rushes towards the two heroes and Genos is then "turned into a piece of modern art" after Carnage Kabuto punched him into the wall. Kabuto then asks to enter the combat experimentation room. Saitama agrees to this because Kabuto "turned Genos into a piece of modern art." In the room, Kabuto then announces to start the killing only to be interrupted by Genos.

Battle
Genos blasts Kabuto in the face with a fire attack which doesn't do anything to Kabuto. Genos then uses his immense speed and propulsors to run around Kabuto to blast him with fire attacks and attack him with his Machine Gun Blows. While he is initiating his attack, he is swapped away by Kabuto and lands on Saitama's arms. Genos then releases a massive fire attack, but Kabuto is able to blow it back to Genos and Saitama. Saitama then takes over the fight for Genos.

Aftermath
Saitama begins to take on Carnage Kabuto after Genos is down.
