Dumb as bricks episode.
How can a person whose quirk is to transform even keep up with Izuku in full cowling? How could she even push him down? He breaks huge rocks and creates aerial shock waves that disperse thrown objects, but somehow, he gets pushed down and pinned by a physically normal human? Instead of pushing her off, he should've just grabbed a part of her body, like her elbow which was in reach of his free arm, and crushed it with his fingers. Then while she is in pain, he should just press his balls onto her sensitive spots and be done with it.
When Izuku realized that Uraraka was fake, why didn't he just smash her face into a wall or something? It's clearly the enemy. Why turn your back to her? He didn't even try to confirm it proactively and just waited for the enemy to reveal herself... WTF. Why did he slap the ball away instead of grabbing the wrist and kicking the shit out of her? Sure he doesn't want to kill people, but hurting them is necessary if they are your enemies. He doesn't even need to injure them seriously.
And why the hell did he explain his reasoning to the already revealed enemy? He just gave up info about Uraraka's new abilities... Geez.
I hate the concept of physical training somehow making up for or competing with quirks. It is ridiculous and denies the very premise of the show.
I swear, people who create shounen manga know nothing about real fighting.
