Double Detroit Smash

Double Detroit Smash (ダブルデトロイトスマッシュ) is a unison Super Move performed by All Might and Izuku Midoriya using One For All.

Description
All Might and Izuku combine their Detroit Smash attacks at 100% of One For All's power to create a smash more powerful than anything they can accomplish alone. This move is powerful enough to destroy a gargantuan steel cube several thousand times their size and weight. For comparison, a Detroit Smash on its own could be blocked by an iron wall.

All Might and Izuku first use this move to defeat Wolfram.
