The following contains spoilers for One-Punch Man Chapter 169, "The Worst Guy I Could Run Into," by One, Yusuke Murata, John Werry and James Gaubatz, available in English via Viz Media.
The world of One-Punch Man is currently recuperating from the massive damages incurred during the great battle between the Hero Association and the Monster Association. Both the heroes and civilians are taken into Metal Knight's care to remove the radiation they received from Garo while the unaffected manpower have begun their cleanup operation. Interestingly, the subsiding chaos also becomes an opportunity for surviving characters to surface.
After knocking some sense into Garo, Saitama finds his home to be in complete ruins. Fortunately, he has already vented all his anger and accepts the current situation for what it is. He takes Genos to the ruins to at least attempt recovering some of their stuff.
Chapter 169 Reveals the Aftermath of One-Punch Man's Great Battle
Chapter 169 of One-Punch Man brought readers to a modern and well-populated apartment building. Three young men went to the newcomer's unit hoping to intimidate and establish the hierarchy, but they were in for a surprise. Instead of some random stranger, it was King who greeted them; he'd also gone there to visit. Unfortunately, he came at the wrong time as Saitama wasn't at home, making him wonder where the bald hero might have wandered to.
In City Z, Pig God escaped from the hospital's confines and was digging through some rubble. Some government agents came to fetch him, but the S-Class hero was adamant about continuing his activity. The A-Class hero Ayer was then forced to make a move and spotted a peculiar puddle of water with eyes. He immediately attacked it with his boomerang, only for Evil Mineral Water to retaliate with a high-pressure stream of water and puncture the hero's throat. Pig God swiftly swallowed the water monster and digested it. Witnessing all these events unfold was another former Monster Association executive -- Black Spermatozoon.
Black Spermatozoon Somehow Survived Its Defeat to Garo
Upon hearing the heroes' plan to sweep the area for any remaining monsters, Black Spermatozoon immediately fled. It wandered in the hopes of finding shelter, but stumbled upon Genos and Saitama instead. The monster immediately realized who the two heroes were and hurriedly hid behind some rubble. Just then, another monster appeared; Pochi, reduced to the size of a common dog, approached the master and apprentice duo. To Black Spermatozoon's surprise, the canine monster was warmly accepted. It then followed suit and pretended to be a monkey.
After seeing Garo obliterate Platinum Spermatozoon, readers of One-Punch Man assumed its death, so this sudden re-appearance has caught everyone by surprise. However, it has already lost most of its power and is now even weaker than a dog. As such, the now-Black Spermatozoon As it attempts to seek refuge from Saitama's camp. Given that it no longer poses any threat, chances are Saitama won't bother with it. Although the hero may not agree to keep the monster, he also may not actively kick it out. As such, the monster may become the latest addition to One-Punch Man's ragtag gang of characters.
