Fumikage is a relatively short person with a bird-shaped head, spiky "hair", red eyes, a striped red choker, a short beak and human teeth. Despite those traits, the rest of his body is that of a regular human shape.
His Hero Costume consists mostly of a dark cloak and clothes that cover his whole body from the neck down.
Fumikage has a reserved, serious and focused personality. Though he does not talk very much, he has been shown directly ignoring questions or requests that seem in some way pointless (like Tenya asking him to not sit on the desk) while he talks to other people as some sort of ongoing joke. When Fumikage teams up with others, he becomes more sociable, helping his teammates out, reassuring his trust in them and thanking them for their effort.
He appears to be fond of darkness and other related concepts, sometimes coming off as a slightly dramatic, such as calling a recreational game a "mad banquet of darkness". Despite this, he is also shown to be embarrassed about his interests to a certain degree, refusing to let his classmates see his gloomy room. Fumikage seems to have a certain level of belief in the concept of fate and destiny, sometimes spouting philosophical expressions.
Fumikage also seems to be aware of his own limits and understands when it's time to back down, surrendering when Katsuki Bakugo forced him into a difficult position to fight back. He takes any advice he gets serious and uses it to try and improve on his Quirk and abilities.
Quirk and Abilities
Dark Shadow (
In spite of its versatility, Dark Shadow's energy is limited and can be drained by sunlight. When it runs out of energy, Dark Shadow retracts back into Fumikage.
According to Mezo, Fumikage's negative emotions (such as regret and indignation) probably intensify Dark Shadow, making it more unruly and possibly making Dark Shadow stronger as a result, albeit at the cost of Fumikage losing control; Fumikage himself stated that his anger causes him to lose control of Dark Shadow.
The personality, strength, defense, and control of the shadow-like monster depends on the lack of light on Fumikage's surroundings. During the day, Dark Shadow is weaker and smaller in size but still has considerable strength and defense as well as easier to control. During the night, Dark Shadow is stronger and bigger which grants it great strength, defense, and size, powerful enough to rip out and cut down multiple trees with ease. However, Dark Shadow is more difficult to control at night, causing Fumikage to lose control.
- Black Ankh (
深淵闇躯Burakkuanku?): Fumikage's special move (previously known as Tenebrous Abyss Body (深淵闇躯 Shin'en Onku?). Fumikage dons and equips Dark Shadow onto himself, wearing it like a suit of armor or an exoskeleton. According to Fumikage, equipping Dark Shadow onto himself mitigates his physical weaknesses.
- Piercing Claw of the Dusk (宵闇よりし穿つ爪 Yoiyami Yorishi Ugatsu Tsume?): Fumikage shoots out Dark Shadow's claw which attacks at great speed.
- Gloom of the Black Arm (黒き腕の暗々裏 Kuroki Kaina no An'anri?): Fumikage shoots out both of Dark Shadow's claws which attack at great speed and then uses Dark Shadow's claws to surround his victims.

Izuku Midoriya remarked that Fumikage is one of the strongest people when it comes to one-on-one battles. Fumikage has shown to be strategical, as he ordered his Dark Shadow to guard his team's blind spot during the Human Cavalry Battle and grabbed one of Shoto's headbands when the opportunity arose. Fumikage managed to hold off Katsuki Bakugo for some time, one of the strongest members in Class 1-A, despite having a Quirk type disadvantage and even when his Dark Shadow was not at full potential. All Might himself acknowledged Fumikage's strength and gave advice to him on how to improve. Shoto Todoroki was amazed by Fumikage's strength after witnessing his Dark Shadow pulverize and defeat Moonfish, a villain that kept both him and Bakugo on the defensive.
