WARNING: The following contains spoilers for Boruto: Naruto Next Generations Chapter 68, “Scar,” by Masashi Kishimoto, Mikio Ikemoto, Mari Morimoto and Snir Aharon, now available in English from Viz Media.
Throughout the sprawling story of Naruto, very few people have been able to contend with Sasuke Uchiha. Orochimaru and Itachi couldn't best him, while many would call his war against Naruto a draw. The Uchiha shinobi later proved to be a thorn in the side of Madara, Kaguya and other Ōtsutsuki aliens such as Isshiki, Momoshiki and Kinshiki.
Sasuke is in a class of his own, which is why many anime and manga fans consider him one of the best characters ever. Admittedly, Boruto has depowered him by having him lose his Rinnegan in the field, but as the fans know, Sasuke still has a ton of styles that make him a one-man army. However, come Chapter 68, he may have finally found his deadliest opponent yet.
Sasuke was missing in action for some time, which is why he couldn't help out when Momoshiki took over Boruto and fought Kawaki in the Konoha forest. This led to Momoshiki having to resurrect Boruto to save his body after Kawaki powered up with his new Karma mark and mortally wounded the Hokage's son. To top it off, Code posed a problem for a Kurama-less Naruto and Shikamaru, which left them missing Sasuke more than ever.
As is usual with this series, he reappeared after the drama with everyone recovering in Konoha, especially the revived Boruto. Thankfully no one else got badly injured, but Sasuke made it clear there was no time to waste. The ranger discovered intel about a snow base Boro had under Isshiki and Kara, which Sasuke suspects has been hoarding weapons such as killer robots and other tech that could be as dangerous as Kawaki. But while he thinks it'll be basic shinobi guards like Bug and co. there, it's actually where Eida, the all-seeing bot, and her younger brother Daemon are.
As a result, when Sasuke arrives thinking it's Code's lair, he'll be in for a surprise. With Eida and Code attacking Konoha, the Uchiha warrior could use a jutsu to get to the lair to destroy it, only to come across the kid. The problem is, Daemon has reflective powers so anything Sasuke throws at him -- from the Katon fire techniques to his Chidori lightning blade -- will be hurled back automatically.
It could be death in seconds, and the sad thing is that without his Rinnegan, Sasuke may not be able to detect anything. Daemon's added advantage is that no one knows about him or this gift, so Sasuke won't even have a heads-up on just trying taijutsu to knock him out.
Instead, when Sasuke raids, Daemon could provoke and lure him into this trap, taking him out instantly and showing the Hidden Leaf that dangerous things do come in small packages. Boruto would be shaping Daemon up as the destroyer Eida teased, and even if he's left alive, it'll prove Sasuke is as vulnerable and human as ever.
