Decided to go ahead and drop him in. Hazama looks like he could use some help.
Name: Hiei
Nickname: Jaganshi Hiei, every short name possible (Thanks to Kuwabara.)
Age: Unknown possibly hundred of years.
Gender: Male
Abilities:
Elemental Resistance: Hiei is resistant to both extreme heat and severe cold (in the anime). This is demonstrated by Hiei's ability to withstand a direct hit from Seiryu the Blue Dragon's Ice Dragon technique, an attack which turned Byakko, another Saint Beast, into a giant ice cube. It has been speculated that Hiei was completely unaffected by the subzero temperature of the surrounding air, and even when Seiryu's attack contacted his body. Also, due to his nature as a fire demon, Hiei is unable to be burned by weaker fire-based attacks. During the Dark Tournament, Hiei takes the full brunt of Zeru's flame attacks which seem to bore Hiei rather than hurt him.
Super Speed: Hiei is one of the fastest characters in the Yu Yu Hakusho universe, being able to slice an opponent sixteen times in a blink of an eye. This has caused some to mistakenly believe he can teleport, when in fact he is just moving very fast.
Afterimage: A side effect of his extreme speed, Hiei can produce afterimages of himself in order to confuse opponents who are unable to follow his movements. While he does have control over afterimages, Hiei usually moves so quickly that he afterimages inadvertently. In nearly every fight he's been in, he has used an afterimage to fool his opponents into thinking they have killed him in one blow, only to appear unharmed somewhere else.
Master Swordsman: Hiei is adept in the art of swordsmanship and carries his trademark "bushido-style" katana. At some point prior to acquiring the Jagan, he acquired a taste for bladed combat, and received lessons in sword technique from Shigure. In the time since then, Hiei presumably developed his own style and exhibits an incredible degree of skill as a swordsman, being capable of delivering multiple precision strikes at lightning-fast speed. Combined with his hyperspeed he attacks his opponent with his sword and if successful can hit up to sixteen times in a second, as just C class, which improves vastly as his powers emerge. Also, Hiei is shown to be able to throw his sword with pin-point accuracy, or even stab through an opponent, completely missing every vital organ and muscle.
Jagan Eye: With his surgically-implanted third eye, thanks to the demonic osteopath Shigure, Hiei can display wide array psychic abilities- including telepathy, telekinesis, remote-viewing, and erasing memories. The eye also allows him to control the minds of both weaker demons and humans. Hiei's abilities with this eye are formidable.
Jaganshi Form: The Jagan also allows Hiei to transform into something called Jaganshi form. In this state, his skin turns green and eyes sprout all over his body. In this form, the power of his Jagan is greatly increased, enhancing his already-great speed, allowing him to paralyze his foes with a binding curse, bolstering his physical strength, and giving him the capacity to summon multiple dragons. Its weakness is that, if anything blinds the Jagan while Hiei is in this form, he will be unable to utilize its powers to the fullest extent.
Jagan Binding Curse (Jagan Tie Curse in the anime): While in his Jaganshi form, Hiei utilizes the enhanced power of the Jagan to completely paralyze his foe. binding his arms and legs in a rigid position. When this occurs, a series of concentric rings of energy are seen surrounding Ythe victim's body, constricting their movements. It has been noted that Hiei's lapse in concentration at that point may have contributed to it breaking, which would suggest that Hiei needs a constant flow of energy to maintain the curse.
Dragon of the Darkness Flame: Hiei uses his demon energy to lure the flames of Demon World and creating a dragon from them. The dragon cannot be controlled, unless the user is capable of absorbing it. Initially, it damaged his arm horribly, but Hiei has surpassed that by discovering that in order to completely control the dragon's power, and have its power at his full disposal, he had to trap it within his own being. Because it composed entirely of black, demonic flames, it completely consumes all it devours. Essentially, it sends its targets to oblivion as a result. Hiei is the only demon to have ever mastered this technique, which is a form of summoning technique, harnessing both the elemental power of a rushing flame and the demonic power of evil.
Dragon Absorption: When he turns the dragon on himself, Hiei gains a massive boost in power, defense, and speed. Kurama says that in order to do this, Hiei had to have had consumed and trapped the dragon within him, binding it to his will. When he first used this technique against Bui, he demonstrated an inability to feel pain, but this may have only been because it was the first time that he had ever used this technique in such a way, which may be confirmed by the fact that Hiei felt pain after using this technique during his fight with Sensui in Demon World, though it may have been that Sensui was able to pierce Hiei's enhanced defense. In this form he can shoot bursts of dark flame from his hands, as well as surround himself with the flames of the dragon to leap high into the air, resembling a "Rising Dragon". There is a drawback, however, in that this technique uses so much power and stamina that Hiei must go into a state of hibernation for a while, at some point after using it, especially if he's made use of the Dragon Absorption.
Fist of the Mortal Flame: Hiei can channel the less-powerful flames of Human World into one or both of his hands. He uses this technique to enhance his hand-to-hand combat abilities, and it also allows him to disintegrate objects merely by touch, as shown by Bui's axe. There seems to be some degree of difference in how the single-handed and two-handed versions of the attack work.
Flamethrower: The flame of the human world can also be used as a flamethrower to create a ranged attack.
Sword of the Darkness Flame: Rather than sustain the damage to his arm after using the Dragon the first time, he instead channeled the flames of the Dragon into the hilt of his broken sword. He's only used this technique as a last resort, and only twice in the entire series, apparently because he finds it cowardly to limit such great power to the form of a sword and also completely devoid of any taste or artistry. In that fight, Hiei first channeled the flames of the Dragon into his sword. In the second try, Hiei created a sword purely from the darkness flame.
Black Dragon Wave: In his Jaganshi form, Hiei is able to release multiple dragons, which results in massive amounts of destruction. It is unknown if this technique was ever mastered. Hiei might have mastered this attack after he achieved S-class energy levels. In this form, he appears to have gained better control over the dragon, given how he can now actually control who the dragons attack.
Astral Projection: Hiei demonstrates the ability to naturally separate his physical body with his spirit.
