The 145th online chapter of One-Punch Man sees Superalloy Darkshine shrug off Evil Natural Water's high-pressure jets to shield Iaian, then join Atomic Samurai in backing up Bang and Genos against Black Sperm's swarming clones.
Atomic Samurai and Iaian keep deflecting a series of high-speed water jets fired by Evil Natural Water. Iaian notices the blasts steadily gaining force, deduces that the monster has been soaking up groundwater, and uneasily wonders what would happen if it drank the entire ocean. A fresh barrage shatters Iaian's blade and nearly runs him through, but Superalloy Darkshine reaches him in time, planting his extraordinarily tough body between the swordsman and the jets. The relentless assault leaves Darkshine untouched. Almost bored, he swats the monster apart with one punch and likens the experience to a bracing high-pressure shower.
At the same time, Bang and Genos are carrying Tatsumaki and Tanktop Master toward Fubuki when Black Sperm cuts them off, swamping them with a horde of clones. Weighed down by the injured heroes they are protecting, the two struggle to defend themselves. Atomic Samurai and Darkshine then arrive to lend their strength against the multiplying monster.
Viz Media titles the chapter Superalloy Blackluster, matching Darkshine's official localized name. The installment shares its title with the volume version of Chapter 112. The volume printing adds pages that lengthen the Darkshine and Evil Natural Water duel, and the panel of Bang and Genos meeting the line of Black Sperm clones was enlarged into a more detailed double spread. This is the online edition.

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....
