Blast is one of the big mysterious characters in One Punch Man, he is recognized by the Hero Association as the best and strongest.

Before that, only very few people had met or knew Blast’s appearance.

Blast tried to help the unconscious Tatsumaki, he was surprised by Tatsumaki’s development, especially her mental strength.

As we’ve seen so far, Blast has never appeared when a monster threat attacked the city.

And finally we have the answer, he and his teammates are having to stop something at the edge of the barrier, but when they are moving through space gaps by the impact of blocks

Combined with the scene where GOD disguises himself as Blast and convinces Tsumaki to receive power, we can see that `it` here is GOD.

This is truly a very surprising thing, no one can think that there are other heroes like Blast outside this dimension.

We still do not know who these mysterious characters are and what their powers are, but they are definitely not ordinary people.
