United States of Smash

United States of Smash (ユナイテッド ステーテス オヴ スマッシュ) is a Move performed by All Might using all the remaining embers of One For All.

Description
United States of Smash is the most powerful technique in All Might's vast arsenal. It is a smash attack that concentrates all of One For All's remaining power into All Might's fist.

All Might delivers an incredibly powerful punch and smashes his target into the ground. The attack appears to compile the strength of All Might's other smash attacks into one spectacular move.

The impact of this smash is so strong that, apon striking All For One, the wind pressure created from its delivery left a massive crater in the ground and spawned a twister strong enough to carry nearby buildings.
