A Battle worn out Genos's headbutt AP??

The bullrush force scales below Genos durability, since Genos head and neck no sold the impact.

I don't think that Genos has star level durability all of a sudden, or even planet level for that matter

It’s just a gag scene

The same headbutt couldn’t harm Pre serious power copied garou

Not to mention half dead genos headbutt shouldnt scale above his actual full body feats and AP scaling to beneath Tats and Psycho

Star level

I read this the wrong way the first time, so I thought the bull rush was Genos' attempt at a hug. Had me laughing for hours.

This Saitama got so many amp he was able to zero punch a Garou that copied him three times before galaxy busting punch with Saitama via squared serious punch.

This feat for Genos is casual multi galactic bare minimum with low ball
