After hearing Flashy Flash’s long story about his past, Blast and others revisited the program related to his ninja skills. At that critical moment, the existence of the character Empty Void was finally revealed. So, what’s new in the revised version of One Punch Man chapter 197?
1. Flashy Sends a Message to Empty Void via Blast

After his arduous tale concluded, Flashy Flash informed Blast of something important. It turns out he only wanted to convey Empty Void’s message to Blast, even though he didn’t know how to explain it clearly. Currently, Empty Void has transformed into a monstrous being manipulated by God. Flashy then decided to leave, while Saitama was still pondering over the ingredients for his meal.
At that critical moment, Flashy also received a challenge letter from Sonic sent through the Hero Association.
2. Blast Discovers Empty Void Will Appear in an Abandoned Building

Following Flashy, Blast and Sitch had to leave Saitama’s house. While riding the elevator, the two discussed Empty Void, specifically the information Blast had leaked to Flashy. It appeared that the hero had a particular personal agenda, so he didn’t want his plans disrupted by Flashy.
Clearly, Blast’s desire to rescue Empty Void from God’s influence remains unchanged, even though One Punch Man has gone through numerous revisions over its storyline. However, the appearance of Empty Void remains a rare opportunity for Blast to realize his plans.
Eventually, Blast also received information regarding the location of Empty Void, which is in an abandoned building.
3. Saitama Decides to Go to Sonic’s House to Conclude Their Match

It turns out Flashy is not the only one who received a challenge letter. Saitama also got a challenge letter from Sonic, sent from a local restaurant. Since he had previously been a part of a chaotic group, Saitama decided to visit Sonic and resolve their ongoing rivalry.
Saitama accepted the challenge because he was tired of being pursued by Sonic’s obsession. He hoped this would be a lesson for Sonic to stop bothering him.
4. Sonic is Observed Using a New Technique as He Starts Fighting Flashy

Flashy had arrived at the area where Sonic was waiting and accepted the challenge. It seemed that Sonic wanted to resolve past issues between them. Despite Flashy stating that there was a significant power difference between them, Sonic appeared to be undeterred by the challenge.
Sonic even began to use his latest technique right from the start of the match. This technique had previously made him lose in a hand-to-hand match against Saitama. Sonic was clearly utilizing a new technique like Saitama’s Serious Side Hops.
