Warning! Spoilers ahead for Undead Unlock chapter 82!
One of Naruto's most famous abilities is the absurd amount of shadow clones he can create to perform impossible feats while Undead Unluck's Andy can leverage his Undead ability to craft clones of himself that are literally made of his own blood to overcome a rather annoying technique.
In chapter 82 of Undead Unluck, Undead Andy faces off against the troublesome foe Billy who can steal numerous mandate-altering techniques for his own use. One particularly irksome ability that Billy recently acquired is the hero Chikara's Unmove, which allows the user to stop the movements of whoever falls in their line of sight. Normally, Andy would be helpless against such a technique except he recently learned a new way to leverage his own Undead ability, which makes the law of life inapplicable to him. Because he can survive without his skin, Andy realizes he can rip it off and release as much blood as possible to serve as a shield. So, when Billy later unleashes Unmove, Andy performs the aforementioned chilling actions so Unmove only freezes the blood surrounding him, allowing Andy to shed the blood-like skin and move away out of Billy's line of vision, thus creating numerous bloody clones of himself. Andy aptly calls it Dead Shadow.
In Naruto, most shinobi don't possess the titular hero's inexhaustible well of chakra, limiting them to only using shadow clones as they're normally intended such as decoys or a means to overwhelm enemies. But Naruto is able to take the technique to a whole other level by creating hundreds of clones, putting into action ideas his predecessors could only theorize about while both mastering and inventing his own attacks. For example, Naruto's teacher Kakashi believed that shinobi could complete weeks- and months-long training regimens in mere hours when training alongside 100 shadow clones because shinobi internalize what their clones accomplish once they disperse. But Kakashi never achieved this since he could never generate that many clones. But Naruto can and does.
Naruto also uses his shadow clones in combination with techniques like Rasengan, a feat even the concept's creator, the fourth Hokage Minato Namikaze, couldn't master. Naruto accomplishes this by summoning a shadow clone that initiates the nature transformation while he and another clone contain the Rasengan, thus creating Wind Release: Rasengan and, upon further shaping, Wind Release: Rasenshuriken.
Although Naruto and Undead Unluck's Andy are able to bring impossible goals to life with their clones, neither of them would have been able to achieve such feats alone. Naruto only possesses the amount of clone-generating chakra he does because he's a jinchūriki and a reincarnation of the powerful Asura Ōtsutsuki. Meanwhile, Undead Andy only gains a better understanding of his powers after an ally transforms him into a book so that his close friend and heroic comrade Fuuko Izumo can enter those very pages to experience Andy's life, where she lives and dies with Andy for 200 years. The fact that Fuuko, whose love for Andy allows her to understand him in ways he can't, is able to meet Andy earlier in his life through this odd method gives her the chance to help Andy gain a better understanding of his Undead ability, as revealed in chapter 44. In addition to leveraging his blood to create clones, Fuuko's guidance leads to Undead Andy using his blood in new and innovative ways such as a form of propulsion when expelled from his body with enough force or a weapon when solidified. Andy from Undead Unluck might have clones grosser than Naruto's, but both of them were equally influenced by others to make the impossible a reality.
