Demons are always scary, powerful monsters across nearly every work of fiction. Their unpredictable Blood Demon Arts, twisted worldviews, and grotesque aesthetics are enough to give even the most experienced slayers nightmares. Here are the five most powerful Demon Moons in Demon Slayer.
Gyokko: Upper Moon 5
Gyokko was #5 among Muzan’s elite Upper Moons squad, a bizarre and short demon with a mouth for eyes and an eyeball for a mouth. He had some pretty flashy abilities and always put a creative spin on all of his attacks. He seemed obsessed with arts and crafts, often working these talents into his combat.
Gyokko traveled between handmade decorative pots, summoned fish-like demons, and even used water to trap his opponents. He nearly got the best of Muichiro, the young Mist Hashira. Luckily, he dispatched him quickly and decisively after activating his Demon Slayer Mark.
Hantengu: Upper Moon 4
Hantengu is the Upper Rank 4 in the twelve Kizuki. At first glance, it might be difficult to understand why Hantengu was appointed to this position among the Upper Moons. He proved himself one of the most formidable opponents in the series.
Hantengu was a coward, but it fueled his power. His Blood Demon Art divided him into his primal emotions. When his weaknesses were attacked, his hatred would take over and attack his opponents.
Kokushibo: Upper Moon 1
Kokushibo was a demon slayer during the Sengoku Era. He became a demon and retained much of his swordsmanship skills. He combined his Breathing Techniques with Blood Demon Art, earning him the Upper Rank 1 position in the twelve Kizuki.
Kokushibo admitted that he became a demon because he wanted to outlive his expected lifespan since he activated his Flame Mark. Surprisingly, Kokushibo is also related to Muichiro, the Mist Hashira. Before he died, he had a child and Muichiro is one of his descendants.
