Megumi is a tall, dark-haired boy with light green eyes (depicted as a dark blue in the anime adaption), and spiky dark blue hair. He wears the standard Jujutsu Tech uniform which consists of a long-sleeved over-shirt with a high collar (featuring a golden button with a swirl that all Jujutsu Tech uniforms have), matching trousers and ankle high boots.
While outwardly stoic and calculating, Megumi wishes to help protect people he sees as good or kind. He believes that the world is unfair and that a sorcerer is a tool to ensure kind people are given more chances to live. Claiming it to be his selfish and irrational desire, he does not see himself as a hero for doing this. This belief that good people deserve saving motivated him to save Yuji Itadori from immediate execution and refused to regret the choice even as Sukuna was about to kill him. On the contrary, he is quite callous when discussing the deaths of criminals and killers as he believes they are not worth saving.
Abilities and Powers
Overall Skill Level: Megumi entered Jujutsu High as a Grade 2 sorcerer and is considered to have high potential by Noritoshi Kamo, Mai Zenin, Satoru Gojo and even Sukuna. The King of Curses notes that Megumi's willingness to use hand-to-hand combat makes him different from other shikigami users, as he is able to use his physical attacks in combination with his shikigami to entrap his opponent.
According to Satoru, Megumi has equal or even more potential and skill than Yuji and later implies that Megumi could even be on par with Gojo himself someday. He can contend with and even defeat special grade cursed spirits, and he and his friends were recommended by Mei Mei and Todo to be Grade 1 sorcerers.
Enhanced Strength: While not as strong as Yuji, Megumi has been shown to possess a high level of physical proficiency, and when he was in junior high, he beat up half the delinquents in the area.
Enhanced Speed: Although not as naturally fast as Yuji and Maki, he has been shown being able to follow their moves and fight alongside them effectively.
Enhanced Durability: Fushiguro has a large amount of durability. He has been shown to take hits from Sukuna at three fingers and from Aoi Todo and survive. He has survived a blow from a Finger Bearer and later won against it.
Enhanced Endurance: Fushiguro has unnatural endurance. He is able to constantly use Domain Expansion despite it pushing him to his limit. He was able to engage in a Domain tug-of-war with Dagon for an extended period of time, and continue fighting with Toji after that, even taking a stab wound and continue fighting and still be able to summon Mahoraga.
Enhanced Reflexes: Fushiguro has considerably better reflexes than others. He was able to react to Awasaka's attacks, dodge Noritoshi Kamo's arrows and even managed to react to Toji's attacks despite not being able to see him.
Weapon Mastery: Although Megumi's technique makes it difficult for him to wield weapons at the same time, as his shikigami need both hands to be summoned, he has started to train with polearms under Maki Zenin. He also once used tonfa to confront Noritoshi Kamo. He often used a jet-black sword, which he was quite skilled with, until it shattered.
Great Tactical Intellect: Megumi has showcased a high level of tactical thinking. He is capable of quickly spotting various weaknesses his opponents may have, being the person to recognize Hanami's branches as his weak spot. Megumi is also capable of determining cursed techniques his opponents may have, shown during the fight him and Yuji had against Jiro Awasaka.
