Spoiler Summary [Click to show or hide]:
In One Punch Man Chapter 138, Genos and Drive Knight, while holding onto Jet Psykos, unleash an…
…energy blast, causing damage. Jet Psykos’s underside bulges and a glowing mouth open in front of them, surprising Genos.
They fall after being hit by a powerful energy blast from Jet Psykos, who then targets Tatsumaki.
Something intercepts Jet Psykos’s beam, revealed to be Tank-top Master throwing rocks, with Fubuki standing behind him.
Tank-top Master continues to throw massive rocks at Jet Psykos, who dodges them while Drive Knight and Genos share energy as they fall.
Jet Psykos dodges the rocks but faces a new robot, a merged form of Genos and Drive Knight named Tactical Combination: Promoted Rook.
They attack Jet Psykos, who becomes enraged. Tank-top Master and Fubuki notice her halt and launch another attack, with Tank-top Master throwing a huge building at Jet Psykos.
Jet Psykos fires a powerful blast at the incoming building, which breaks to reveal inside Puri-Puri Prisoner, Darkshine, and Atomic Samurai, who deflect the beam.
They jump out and launch attacks, with Atomic Samurai, using “Atomic Beeline Slash” to cut Jet Psykos in two.
Puri-Puri Prisoner grows wings and attacks with “Vibration Dark Angel Rush” while Darkshine unleashes “Superalloy Missile,” hitting Jet Psykos.
Psykos jumps out of the monster’s body, prompting Bang and Bomb to attack with “Cross Fang Dragon Slayer Fist,” causing the monster to fall.
Fubuki notices something, and as Tatsumaki powers up, Flashy Flash looks relieved after escaping the rubble, but still with one hand stuck in it.
Saitama picks up a cube and throws it on the ground.
Suddenly, the ground shakes and the tower detaches and floats upwards. Tatsumaki maneuvers it into a massive glowing spear aimed at Monster King Orochi’s remains.
