Whether it's the poros incident or the strange snake incident, we all know this kind of thing in the later period of the original work, and the cards of the Hero Club have not been completely played. The metal knight didn't even make a move, and the pig god also had a salvation card, but it wasn't time. These people could see that these events should be inconsistent with the divine disaster predicted by Baba's mother-in-law, so the blasting didn't appear!
When poros appeared on the earth, blasting didn't appear, because blasting didn't even know there was poros. The only person who has seen poros and fought poros is Saitama. Blasting didn't appear at that time, probably because blasting thought it hadn't appeared yet. Because the heroes at that time only saw the spaceship, and this time the disaster level was only dragon. Not up to the level of god. Blasting felt no need to go out by himself. If the bomber knew about poros. I think an explosion is bound to happen. Moreover, I know that there is Saitama and I know the strength of Saitama. With Saitama around, blasting can rest easy. The eccentric snake king is the villain in the remake, and the explosion has been around for a long time, so the existence of the eccentric snake king is probably unknown.
Of course, if we are bolder, because the explosive suit is very similar to Saitama's combat suit, it may really be related to Saitama. This connection includes: 1. Saitama wore a wig and went over to save the tornado. Some people suspect that it may be Saitama's father who exploded!
I hope my answer is helpful to you. I hope it can be adopted. Thank you.
