Heroes vs. Psykos and Orochi

They just keep coming. To dare oppose the culmination of my evolution... Foolish inferior life forms!

S-Class Heroes vs. Psykos and Orochi is the battle between the S-Class heroes Tatsumaki, Genos and Drive Knight against the leaders of the Monster Association, Psykos and Orochi.

Prelude
Tatsumaki is battling the leaders of the monster association, Psykos and Orochi, who have gained the upper hand and have rendered her helpless. The disfigured fusion of Psykos and Orochi prepares to finish her off with a massive energy attack. Just as they launch their beam, it is intercepted by a wave of energy from the ground, which launches both beams into the sky.

Meanwhile, in the distance, Drive Knight and a sedated Nyan watch the battle. Intent on capturing a sample of Psykos and Orochi's flesh, Drive Knight severs an underground power cable to recharge his depleted energy, then heads toward the battlefield.

Battle
Psykos, Tatsumaki, and many spectators watch as a "blue dragon," Genos, circles the tower. Genos uses Thunder Drill Cannon to attack the fusion head-on, but his attack only succeeds in deflecting the fusion's beam. Orochi's dragons attempt to attack Genos on their own, but Genos matches them with his own lasers. Tatsumaki chides Genos for interrupting the battle, but Genos rebuffs her and tells her to finish off the fusion while he deals with the energy beams. He laments having to use his full power so soon, and recalls Dr. Kuseno's warning about his newest upgrade - it can only be used for ten seconds. The two heroes face down the monster as Genos wonders whether they will make it.

Psykos and Orochi proceed with relentless attacks towards Genos and Tatsumaki. Genos finally uses his full-powered attack True Spiral Incineration Cannon, which succeeds in temporarily neutralizing the fusion's beams. This allows Tatsumaki to pull the majority of the heroes on the assault team to safety, except Flashy Flash, Iaian, Zombieman, and Pig God (though the latter hero arrives independently shortly afterward.)

Unfortunately, Genos quickly fries himself using his own power due to the ten-second limitation and is rendered helpless. Tatsumaki, having made a recovery by then, congratulates Genos on his accomplishments and easily redirects the energy beams fired from the fusion. Using the vast extents of her psychic powers, Tatsumaki manages to suppress Psykos and Orochi while destroying its roots and body by "wringing" it dry. This ability was so powerful that it completely distorted the landscape of Z-City.

As the night begins to set, Psykos and Orochi are nearly defeated. However, due to the previous injuries and her usage of a substantially powerful psychic move, Tatsumaki is pushed to her limit. Psykos senses this and immediately utilizes a large smokescreen to temporarily blind Tatsumaki while utilizing what's left of Orochi's destroyed body to create an organic fighter jet. As Psykos plans to absorb the blood and flesh of the city, she copies Tatsumaki's move and creates multiple decoys in order to scatter her presence and escape.

Psykos taunts Tatsumaki of the limits of her power, however, Tatsumaki's psychic power is unfaltering as she creates a double-layered barrier that is completely immune to direction inversions. Due to this, Psykos decides to fire an energy beam at Tatsumaki frontally as such a large barrier would supposedly take up all of her concentration. Unfortunately, the beam only struck a decoy, while also serving to reveal Psykos' current location.

Before Tatsumaki could launch a proper attack at Psykos, Drive Knight interrupts the battle by firing two energy beams in an unnamed jet transformation. One of the beams strikes Psykos as she expresses her frustration from the unrelenting attacks, Drive Knight on the other hand seems eager to collect samples of Psykos and Orochi. The chase continues in the air as each side fires multiple energy beams at each other. While Psykos is able to temporarily neutralize or evade all of Drive Knight's attacks, a weakened Genos drops to the ground and quickly explains the situation to the rescued S-Class heroes. He pleads with the heroes to assist in the fight, then gathers himself and returns to attacking Psykos with his own energy cannons.

Atomic Samurai acknowledges Genos' plea and tries to hit Psykos with his Air Blade, but the attack's range is too short. Falling back to the ground, the hero watches Drive Knight, Tatsumaki, and Genos fighting, shocked that the three are actually cooperating. Pig God releases Iaian, Zombieman, and the unconscious members of Narinki's Private Squad from his mouth, revealing that he had rescued them on his way to the surface. Tanktop Master, noticing the severity of the fight from afar, also decides to head to the scene. While the remaining heroes on the surface regain their composure, Child Emperor devises a plan of attack.
