@SSS26032002 maybe its because she cant distinguish op and really weak? like sound waves, you cant hear something if the frequency is too low or too high. maybe thats what she experienced with blast and she assumed that king is also the same? idk, dont really have proof so this is just a hypothesis
@penguinsans I can be wrong about this but I heard from a source that One once said that Tatsumaki was stronger than Mob even at his 100% (???% is akin to Saitama's and God's power level). Mob can see other people's powers fine if he tries to control his powers as shown in the scene where Mob can detect Reigen to not be an esper even before Reigen telling him. It's also a possibility that I'm just joining pointless dots between two unrelated series.
