Damn Tatsumaki was badass this chapter
.
So it seems like she wasn't going all out due to heroes being around
Genos on the other hand played his part by countering some of Psykorochi's attacks and saving Tatsumaki multiple times when she couldn't go all out
I think Psykorochi isn't dead yet or at least not Psykos, but if a city distortion lvl attack destroyed their fusion / finished them, then outside of her initial introductive attack, she wasn't as impressive stats-wise(combat speed, durability, etc..) as I thought she'd be.
