1,000,000% Delaware Detroit Smash

1,000,000% Delaware Detroit Smash (パーセント デラウェアデトロイトスマッシュ) is a move performed by Izuku Midoriya using the One For All Quirk.

Use
During Izuku's fight versus Muscular at the Forest Training Camp Izuku uses this attack in order to defeat Muscular and effectively protect Kota, the attack has serious firepower, as proven by its ability to knock out Muscular while he was using his Muscle Augment quirk.

Power
The 1,000,000% Delaware Detroit Smash is Izuku's strongest attack in his arsenal. This attack outputs both the power from a Delaware Smash and a Detroit Smash. While Izuku does claim that this attack is at 1,000,000% of his power, this was proven to be inaccurate and false, he was using both his 100% Delaware Smash and his 100% Detroit Smash at the same time, outputting both the powers of the attacks at once. There were huge repercussions however, as his right hand suffered major injuries and was warned that if he was to use the same attack two or three more times his right hand will be completely paralyzed.
