The following contains spoilers for One-Punch Man Chapter 171 “Secret Information” by One, Yusuke Murata, John Werry, and James Gaubatz, available in English via Viz Media.
one punch man being a joke manga gives rise to many unique characters, both in terms of appearance and personality. The series has so many idiotic superpowers and villain origin stories that it’s hard to predict what to expect from characters yet to be introduced. One of these mysterious characters finally steps forward in Chapter 171 of the manga.
The fight between the Monster Association and the Hero Association has officially concluded with the abolition of Garo’s divine powers. The S-Class hero, Metal Knight, is also in charge of resolving the side effects of the battle. He rids the battlefield of any residual radiation and cares for those wounded during the war. It also turns out that he is the one behind the new Hero Association headquarters, as well as the security system that protects it.
Dr. Bofoi, the man behind the robot army
After Saitama lost his place during the Monster Association’s attack, he returned to the ruins to search for his lost belongings. It was recently revealed that she was residing in the new headquarters of the Hero Association. The bald hero was already promoted to Class A, granting him special life privileges. But during one of his excursions, he picked up Overgrown Rover and Black Spermatozoon. By the time they got back to the base, his defense mechanism activated and the robotic defenders started attacking the monsters. However, Saitama defended the new teammates from him, resulting in multiple robots being destroyed.
After the event, a certain individual viewed the records of the fight. He discovered that even his level 10 robots, which could supposedly defeat two Demon level monsters, were crushed. That person was none other than Dr. Bofoi, the man who wore the hero name Metal Knight. Surprisingly, the scientist looked like your typical unassuming old man, although his upper teeth were sticking out.
Saitama arouses the interest of Dr. Bofoi in Chapter 171
Seeing his proud creation being destroyed logically made the scientist interested in the culprit behind it. Unlike the others who bought into the sleazy robot narrative, Dr. Bofoi/Metal Knight only believed in cold facts. He searched through Saitama’s information and discovered the hero’s outstanding performance from Cape Bald. He started out as a C-Class hero just three months into the current timeline and was immediately promoted just a month and a half later. Even Dr. Bofoi was surprised at how quickly this rookie hero rose, so he did more research on Saitama’s exploits.
It was then that the doctor discovered something strange. Saitama was present during the world’s most threatening events: the destruction of the giant meteorite, helping to defeat the Deep Sea King, and the clash with the human monster Garo. And yet, none of the records of him suggest power beyond the ordinary. Even Saitama’s test results during his initial hero evaluations simply had a note stating that he had broken previous physical records.
The discrepancy between the images and the records piqued the interest of Dr. Bofoi. Although there was still no incriminating evidence, he decided to keep an eye on Corporal Bald in case the rookie hero posed a threat to him. As for why a competent hero could be a threat to him, only future developments of one punch man I can say.
