Yes, he will. Based on the way One For All works, each wielder masters the power, improves it to the point where they surpass the last wielder, then passes it on to someone else. As Izuku is learning to harness more of One For All, he's also developing his own way of using it.
My Hero Academia: Endeavor Confirms Deku Has Already Surpassed All Might. In chapter 356 of My Hero Academia, Endeavor is accosted by a younger version of himself in a shocking way that reveals his true feelings. Warning! Spoilers ahead for My Hero Academia chapter 356!
Midoriya was able to use 100 percent of One For All against Overhaul. This was done since he wanted to bypass the effect of her quirk and destroy his body faster than her rewinding his body.
1 Deku Never Will Beat: All For One
Not the version we've seen him in, at least. All For One is constantly shifting, thanks to his ability to take quirks. That means we will never get to see Deku face the version of All For One that cost his mentor so.
Based off sheer strength of 100% OfA, then Deku wins. This is because, canonically, One for All gains kore power as it's passed on, so each time it gets a new user, that user's 100% is stronger than the last.
How It Works. Deku's final quirk is known as 'gearshift'. It's a quirk that is activated via physical contact. It allows the user to change the velocity of anything they touch, meaning they can spontaneously slow things down, or speed things up.
One For All is one of the strongest Quirks in My Hero Academia, if not the strongest. It allows the super to stockpile incredible amounts of power within their body which, when released, grants a tremendous boost in power.
As of now, Deku has access to seven Quirks, namely One For All, Transmission, Fa Jin, Danger Sense, Blackwhip, Smokescreen, and Float. The basic gist of all these powers is that they all come from the previous One For All users, with their abilities becoming stronger throughout the generations.
According to Deku's mother, the inherited quirk Deku should've naturally received would've either been his father's quirk, breathing fire, or her own ability to levitate small objects.
Izuku does not claim that he's using One For All at 1,000,000%, it's only the fighting spirit of Izuku's way to shout his feelings toward this unusual strength in an emergency. Basically he is not actually using 1,000,000% of One for All but is just unnecessary yelling for him using over 100% of his power.
During the Dark Hero Arc, Izuku's strength increases even further and he can now use 45% as his regular output with no backlash.
After observing how the quirk reacted to the bodies of the users, all the previous wielders concluded that One For All could not be held by a user who already had a quirk. Thus, Deku is the last successor to the quirk, making him their last hope to take All For One down.
Deku is clearly above the rest of the heroes right now
Transmission. During the final war, Shigaraki was able to defeat multiple Pro Heroes without even using his Quirks. Over at the U.A. battlefield, he took on the likes of Mirko, Best Jeanist, Edgeshot, Bakugo, and the Big Three.
Bakugo is the only student who knows Deku's secret which puts him in a unique position to protect Deku. Bakugo is questioning All Might out of concern atonement is a theme of the series and Bakugo is aware of how he's harmed Deku in the past and has tried to make up for it by protecting him.
Bakugo was stronger than Midoriya, though he indicated that Midoriya could eventually surpass him.
Gentle Criminal may not seem threatening for a My Hero Academia villain. However, during the School Festival arc, he gave Deku a very challenging fight. To put it into perspective, Deku even told Gentle Criminal that he was the hardest villain he has fought so far.
4 Stronger: Endeavor
He was the one rallying the Heroes and fighting Shigaraki Tomura for the sake of peace. Endeavor did a magnificent job in the arc, and his character was fleshed out further, taking him closer to his redemption. Endeavor, being the strongest Hero, was easily better than Deku in the arc.
1 Deku and Bakugo
Since Deku was Quirkless ever since he was a kid, Bakugo often bullied him because of how weak he was. However, after receiving the One For All from All Might, Bakugo's frustration culminated in him eventually acknowledging Deku as a rival when the two fought.
Izuku was raised primarily by his mother Inko, who has the ability to make small objects float towards herself. His father, Hisashi, whose quirk allows him to breathe fire, is not seen due to him working abroad in the United States.
Deku Begins His Dark Arc In My Hero Academia Season 6 Episode 19.
Why does Deku become a villain? The concerns surrounding Deku grew after he awoke his new quirk Black Whip, originally belonging to Daigoro Banjo, one of the inheritors of One for All. Deku was unable to control its powers and its generally dark and intimidating image didn't help his case.
1 Shigaraki
All For One is arguably the rarest and most powerful Quirk possessed by any villain in My Hero Academia. This Quirk so thoroughly defines its bearer that he's taken it as his name.
