Deku, despite his impressive training and spirit, faced a fierce challenge against Ace, who’s packing not just brute strength but also an arsenal of high-tech weaponry. While Deku has that indomitable hero spirit, Ace’s combat abilities, especially when rage mode kicks in, pushed the dial way beyond the limits of what Deku can handle. Ace could boost his stats tenfold in Rage mode, which is like throwing a bomb into a kiddie pool; it just doesn’t mix. With his tactical suit, he’s practically a walking cannon. The speed advantage Ace holds means he’s blitzing in and out, raining down fire and fury. Let's break it down: Sure, Deku's got raw talent and heart, but Ace has technology on his side and an explosive rage mode that comes in like a freight train. You can’t teach a heart, but Ace’s skills and suit give him the edge in this brawl. The boy from UA is tough, but Ace is rougher, fueled by his mechanized prowess.
