Deku's growth is evident with his enhanced Delaware Smash, a technique that would impress even the former Symbol of Peace.
Summary
Deku's command over One for All now allows him to use the Delaware Smash without self-injury, showcasing his significant improvement. By merging this technique with the Third's Fa Jin Quirk, Deku generates a powerful wave capable of halting Shigaraki's destructive Decay, highlighting his extraordinary power. Despite the looming possibility of parting with One for All, Deku is proving himself a worthy successor to All Might, matching the strength of the Symbol of Peace.
Throughout My Hero Academia, Deku has tirelessly worked to follow All Might's example, an almost impossibly pure hero who defined heroism for a generation. Though Deku still has a journey ahead to become such a symbol, his raw power now seems to rival his mentor's, especially with his latest execution of the Delaware Smash.
The Delaware Smash was one of the first techniques Deku devised independently, rather than borrowing from All Might's arsenal. Introduced in chapter #15 of the manga, this move initially caused Deku's fingers to break upon use. However, Deku has since mastered One for All, enabling him to use the Delaware Smash without harming himself.
Deku's Strength Is Finally On Par with All Might
Faced with Tomura Shigaraki's threat, who aims to destroy Mount Fuji, Deku employs the Delaware Smash under dire circumstances to counter Shigaraki's Decay Quirk. Deku has an advantage All Might never had: access to the other Quirks within One for All. This allows him to augment his Quirk's power in new ways, achieving incredible strength rapidly. As Shigaraki's Decay advanced towards Mount Fuji, Deku combined the Delaware Smash with the Third's Fa Jin Quirk, creating a massive pressure wave that stopped the Decay.
Executing this technique with just his fingers and the resulting air pressure to carve out a huge section of ground demonstrates Deku's immense power. Supplementing his muscle strength with Blackwhip, which he wraps under his skin, Deku achieves feats reminiscent of All Might, such as altering the weather with a single punch. Deku is proving his mastery over One for All, now operating at All Might's level.
Deku May Have to Part Ways With His Quirk Just as He Masters It
The chapter concludes with the notion that Deku might part with One for All, a poignant development given his recent All Might-level accomplishments. Even if this happens, My Hero Academia fans have witnessed Deku's incredible power, affirming his worthiness as the heir to both One for All and the Symbol of Peace, All Might.

My Hero Academia
In My Hero Academia, some humans possess superpowers known as quirks. Izuku Midoriya, nicknamed Deku, was initially quirkless. Despite this, he idolized heroes like All Might, the number one hero, and dreamed of becoming one himself. His lack of a quirk held him back until a chance encounter with All Might, after Deku rescued a classmate, set him on the path to heroism. The series follows Deku and his classmates at UA, a school that trains young quirk users through rescue missions, combat training, and other hero-building tasks. With Deku inheriting the "One For All" quirk, he learns what it means to be a true hero while confronting formidable villains.
