Fumikage Tokoyami, aka Tsukuyomi or Jet-Black Hero, is arguably one of the most eye-catching characters in My Hero Academia, and with good reason. He's a character with a very visible quirk – having the head of a bird, yet the body of a human.
Tsukuyomi is one of the most stable students going to U.A., he seems to perfectly understand his abilities and their limits (and thus their weaknesses). This isn't something to be taken for granted, as the series has managed to prove time and time again.
10 Dark Shadow
Tsukuyomi's quirk is one that truly deserves to be given a name – Dark Shadow. His quirk is quite literally a sentient shadow, one capable of rational thinking. Also, Dark Shadow is also capable of losing control.
Because Dark Shadow is its own entity, it gives Tsukuyomi a huge advantage; a second pair of eyes and hands to use in battle, among many other things. On the whole, Tsukuyomi and Dark Shadow seem to get along, though Dark Shadow does come with his own weaknesses and risks.
9 Control Issues
As mentioned above, Dark Shadow comes with some serious control issues. Fans of the series will recall the time that Tsukuyomi lost control of Dark Shadow, resulting with a very dangerous antagonist getting taken down like he was nothing.
Tsukuyomi has trouble maintaining control over Dark Shadow in darker settings. It's something he has been actively working on, but it is easier said than done. Unfortunately, losing control doesn't automatically mean that Dark Shadow will only target the antagonists in the area – anyone nearby is fair game to him.
8 Understanding His Limits
Tsukuyomi is a sharp and intelligent character, fully aware of his limits and the risks of pushing said limits. He would have to be, given his quirk and all of the risks that come with it. He's a competent ally, and never once have we seen him hesitate to inform his allies of his uses – and the best way to utilize his skills.
This level of self-awareness isn't exactly uncommon in the series, but neither is it common. Tsukuyomi is one of the few in Class A who can honestly (and fairly) asses themselves, and that is likely the reason we rarely see him lose control.
We've seen many of the U.A. students get tutors over the course of the series so far. That was half the point of the U.A. Sports Festival, after all. Obviously, Tsukuyomi is no exception. He managed to catch the eye of Hawks, who at the start of the series was the third-ranked hero.
Admittedly, Hawks may have paid extra attention to Tsukuyomi due to their similarities in themes, but the Pro Hero proved to be a useful trainer all the same. Because of Hawks, Tsukuyomi learned how to use Dark Shadow at a slightly greater range, among other things.
All of the students face constant rankings while at U.A. It's a high-pressure environment, but it's an area in which Tsukuyomi has consistently excelled. He has so far managed to appear higher up in all of the rankings and seems to do so with minimal effort.
Tsukuyomi ranked ninth in the U.A. Entrance Exam, and fifth in the Quirk Apprehension Test. Finally, Tsukuyomi earned third place at the U.A. Sports Festival. He will likely continue to rank as the series goes on as well, but only time will tell.
5 His Potential
It is a rare thing to see a student consistently acknowledge by their peers and instructors, but Tsukuyomi has somehow managed this task. Early on, Midoriya was impressed by Tsukuyomi and his ability to asses the situation (and himself). Later, Tsuyu and All Might commented on the hero-to-be as well.
Of course, let's not forget that he had caught (and held) the attention of Hawks, a high ranking hero by any standard.
4 Strength in One-On-One
Tsukuyomi is a character that you're better off not trying to fight one-on-one, or in close range. His quirk and his fighting skills will make for a difficult matchup, no matter who it is. Take Bakugo, for example. Bakugo quite literally carried Tsukuyomi's weakness, fire (bright lights). Yet Tsukuyomi made Bakugo earn that win, an impressive feat.
Between Tsukuyomi and Dark Shadow, they can cover a 360 area around themselves, protecting and attacking as one unit. They can also act independently, making them a double threat through and through.
3 Cooperative Nature
Like any in-depth series, the students in My Hero Academia are put through a series of rankings, as well as facing an overall rating of their skills. Tsukuyomi caps out on the ability to cooperate with those around them – a fact that he has proven at every opportunity.
We first saw this ability back during the U.A. Sports Festival – here he didn't hesitate to tell Midoriya his weakness, all in hopes of helping to balance out the team and increase a chance to win. That same fight, he saved the day with his quick thinking. Later, he worked and adapted perfectly with any of the teams he's been thrown onto.
2 Black Ankh
During Tsukuyomi's attempts to become a better and stronger hero, he has developed a few new moves. One of them is called Black Ankh. Black Ankh is special for several different reasons. The core of the new ability involves him taking Dark Shadow on as almost an outer suit – having the two become one.
The ability also has three elements to it. Naturally, these secondary traits have all been named; Piercing Claw of the Dusk, Gloom of the Black Arm, and Black Ankh Sabbath. Piercing Claw of the Dusk is more or less what the name indicates; Tsukuyomi can shoot out Dark Shadow's Claws at a decent range and speed.
Gloom of the Black Arm also fits the name. Here Tsukuyomi enlarges the arms of Dark Shadow (who again, is coating Tsukuyomi) in a move that increases damage. Finally, Black Ankh Sabbath allows Tsukuyomi to move faster than his standard speed, thanks to another new ability (see below).
1 Black Fallen Angel
Black Fallen Angel is the newest ability that Tsukuyomi has mastered. Like Black Ankh, this ability will likely stay truly unique to Tsukuyomi. In many ways, this new technique is an extension to the previous ability. Though it does increase his maneuverability and range by quite a bit.
Once again, Tsukuyomi is enveloped by Dark Shadow, but for a different purpose. Here the hero is supported and carried by Dark Shadow. This grants him a limited ability in flight. As if Tsukuyomi wasn't intimidating enough as he was!
