The abilities portrayed in anime vary, and their uniqueness often leads to interesting storylines and action-packed scenes. While some characters get to wield dark magic, others get to change their size at will. Although changing one’s size seems like an inferior power, in the hands of skilled writers, animators, and characters, the ability is one to covet.
From shrinking down to the size of an ant to growing to tower heights, characters blessed with the size alteration ability use their incredible power to navigate through any situation, overcome any obstacle, and even use their size-changing abilities to gain an advantage in battle.
7 Mt. Lady
Yu Takeyama, with the hero name Mt. Lady, is a pro hero in the My Hero Academia anime series. With her quirk of gigantification, Yu can remain at her normal height of 162 cm or grow into a towering figure of 2,062 cm. Although she uses her ability to change her size at will to fight villains and protect civilians, Yu’s power comes with limitations.
While using her gigantification quirk, Mt. Lady can grow many meters taller, making her a formidable opponent against most villains. The downside to her ability is that it requires a lot of energy and physical exertion, so she cannot maintain her giant form for too long. Furthermore, she cannot grow to any size between her giant height and her normal height.
6 Choji
Coming from the shinobi Akimichi clan, Choji Akimichi from the Naruto anime series has the ability to expand and increase the size of his body at will through a power known as the Expansion Jutsu. This jutsu allows him to manipulate his body size and weight to enhance his physical abilities and perform unique jutsu techniques.
Choji's expansion ability allows him to increase his size and strength, making him a formidable fighter in battle. His expansion jutsu also has some strategic advantages. By increasing his size, he can cover a larger area, making it harder for enemies to avoid his attacks. It also allows him to block pathways and restrict the movement of his opponents.
5 Rimuru Tempest
As the main character in the That Time I Got Reincarnated as a Slime anime series, Rimuru was formerly a mid-age salaryman before he was killed and reincarnated as a slime. As an evolved slime, Rimuru has the unique ability to change his size and shape at will, making him a versatile and unpredictable fighter.
In battle, Rimuru often uses his size-changing ability to his advantage, using his smaller form to evade attacks and his larger form to overpower enemies. He can also change his body composition to mimic the properties of other materials, such as turning his body into a crystal-like substance for defense or mimicking the properties of fire or water for offense.
4 Kibutsuji Muzan
As the Demon Slayer’s primary antagonist and the progenitor of demons, Muzan Kibutsuji has many abilities. One of his abilities is being able to change his size and form as he sees fit. This ability helps him blend into crowds while evading capture, but it does not stop there.
Muzan's size-changing ability also grants him immense changes in his physical strength and agility, making him a formidable opponent in battle. He can increase his size to towering proportions and deliver devastating blows, or shrink down to evade attacks and strike with precision. However, Muzan mainly changes his size to take on different forms so that he can move unhindered among humans and demons alike.
3 Tony Tony Chopper
Portrayed in the acclaimed One Piece series, Tony Tony Chopper has the unique ability to alter his size and appearance as he pleases due to his Devil Fruit power, known as the human-human fruit. Originally a reindeer, Chopper consumed the fruit, which granted him the ability to transform between his initial reindeer form and a more human-like form.
Chopper's size-changing ability is particularly useful in battle, as he can alter his form to fit the situation. He can shrink to a small size to evade attacks or hide from enemies, or he can increase his size to become a formidable opponent in combat. Moreover, Chopper can also transform his limbs into powerful weapons, such as hooves or antlers, allowing him to fight with great strength and agility.
2 Lily Enstomach
Of the many giants portrayed in One Piece, Lily Enstomach stands out due to her devil fruit ability. With the mini-mini devil fruit, Lily can shrink down to a tiny size or go back to her normal giant size, making her unpredictable in her delivery of attacks.
In combat, Lily's size-changing ability allows her to evade attacks and confuse opponents. Unlike many other characters with size alteration abilities, Lily regains her massive giant strength even while she’s in her tiny form. This single ability makes Lily more destructive than her enemies can imagine. Unfortunately, she was only portrayed as a side character in the One Piece series during a filler arc.
1 Nezuko
The Demon Slayer anime series features Tamado Kanjiro on his quest to kill Kibutsuji Muzan, the progenitor of the demons, and save his sister by turning her back into a human from her demon form. Nezuko has many superhuman capabilities as a demon, but unlike many demons, she does not eat human flesh to gain strength.
One of Nezuko’s many extraordinary traits is her ability to change her size at will. From a diminutive and innocent-looking girl to a towering demon with incredible strength, Nezuko’s size alteration ability helps in many situations. Whether it be to dodge attacks or fit inside a wooden backpack, Nezuko’s size alteration ability helps a ton.
