The online-numbered 158th chapter of One-Punch Man, titled 2Bad, pushes the Garou and Metal Bat pairing against Sage Centipede's regeneration, revealing a resonance that magnifies the wounded hero's power as Garou tears out the monster's healing core.
Garou and Metal Bat open with their Roaring Aura Sky Ripping Fist and Savage Tornado, yet Sage Centipede's durability and swift regeneration shrug both aside. Respecting Garou's strength but dismissing Metal Bat, the monster considers taking the hero hostage and resumes chasing the helicopter carrying Tareo and the injured heroes. When One Shotter tries to snipe its head, the loss of his specialized right eye throws off his aim and he misses.
Sage Centipede snares the helicopter with its antennas, wrecks the rotor, and seizes the passengers, then unleashes its Centipede Grand March, reshaping the ground and striking the two fighters. As a monster arm grips the kneeling Garou, One Shotter, steadied by Gearsper, finally lands a shot to its eyes and buys Garou an opening. Cheered on by Tareo, who mistakes him for a hero, Garou works to free the helicopter, and a badly hurt Metal Bat slices off the antennas.
Fueled by his Fighting Spirit, Metal Bat surges in strength and directs Garou to a rescue net 500 meters away, where Garou flings the helicopter to safety. Enraged, the centipede charges with its 6666 Leg Grand Drill, but Garou's Cross Fang Dragon Slayer Fist and Metal Bat's Savage Hurricane form an accidental combo that cracks its shell. Their strange resonance keeps boosting Metal Bat until the monster knocks him aside, while Garou pierces the body and rips out the regeneration core, ending its healing. He hurls the core skyward, and both racer and monster give chase as Metal Bat finally collapses, telling Garou to finish the job.
Garou and Metal Bat's techniques initially fail against Sage Centipede's regeneration. One Shotter, aided by Gearsper, frees Garou with a precise shot. A resonance between the two fighters amplifies Metal Bat's power, letting them crack the shell, and Garou extracts the regeneration core and throws it into the sky before Metal Bat passes out from his injuries.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
