It's surprising that Blast has an ally who looks like the character Boros in One Punch Man.
There are some intriguing details from the latest chapter of One Punch Man. Among them is the battle between Garou and Saitama.
Additionally, there's a moment when Blast (in another dimension) realizes that something is amiss on Earth. Subsequently, some colleagues working with Blast are shown. Among them is an individual resembling Boros, causing netizens to be surprised.
Following this, One Punch Man fans are highly curious about this Boros-like character! Below are some fan theories about Blast's colleague.
1. Boros was rescued by Blast
A prevailing theory among the One Punch Man fan community suggests that Blast's colleague is indeed Boros. He was rescued by Blast after losing to Saitama and is currently working with the Earth's number one hero.
However, there's an issue with this theory. If he truly is Boros, he should have introduced Saitama to everyone to recruit him, knowing the caped baldy's tremendous power.
In the frame where the Boros-like character speaks, the character resembling Beast King mentions that he can't imagine any Earthling causing the phenomena they witnessed. So if that's Boros, he should respond that Saitama can do that.
The Boros-like individual doesn't even comment on Saitama, so perhaps this is someone else.
2. The hypothesis that this is Boros from another dimension
Another possibility is that the Boros-like character is Boros from a different universe. Chapter 210 of One Punch Man shows that Blast and his associates are in a different dimension.
This leads many to believe that perhaps Blast has been exploring alternate dimensions over time, which is why he's been absent on Earth despite numerous events occurring. From here, people speculate that Blast's colleague resembling Boros may come from a different dimension that Earth's hero has visited. In that place, Blast faced characters like Boros and Beast King, not Saitama.
Afterward, Blast could have recruited his foes to become allies. This also explains why the Boros-like character doesn't mention Saitama. He might not have even met Saitama in his original dimension.
3. Sharing the same race as Boros?
Another possibility (and the simplest one) is that Blast's colleague actually belongs to the same race as Boros, but he's not Boros himself.
If so, Blast's ally probably isn't as strong as Boros since Boros is the strongest in his species. And because he's not Boros, he doesn't know Saitama.
