Delaware Detroit Smash is the strongest smash move in Izuku's arsenal. He uses both his 100% Delaware Smash and his 100% Detroit Smash at the same time, multiplying their destructive power into one attack.
By utilizing his adrenaline and raw emotion, Izuku supercharges One For All with enough power to perform this smash attack.
- 1,000,000% Delaware Detroit Smash is featured as Izuku's ultimate move in Jump Force.
