Neito Monoma's quirk, 'Copy,' is this wild ability that lets him temporarily steal other people's quirks just by touching them. It's like he's borrowing their superpowers for a limited time—usually up to about 10 minutes, though the exact duration isn't set in stone. The catch? He can only hold one copied quirk at a time unless he stacks them using gloves or other storage methods, which is pretty clever if you ask me. He's got this whole theatrical vibe going on, too, which makes his fights way more entertaining.
What's really interesting is how Monoma uses his quirk strategically. He's not just borrowing powers randomly; he studies his opponents and picks the quirks that'll mess with their heads or counter their moves. Like when he copied Kirishima's 'Hardening' during the joint training arc—pure psychological warfare. The guy's a genius at mind games, and his quirk lets him play those games perfectly. Honestly, it's one of those abilities that seems simple at first but gets scarier the more you think about it.
