Alias/Aka(also known as): Haku of the Ice Release
Classification: Human ninja
Threat level: Tiger+ || Tiger+
Destructive capacity: Building (Needles have higher potency however as it focuses his power on a small point and usually target vitals), likely higher (Zabuza held Haku in high regards, even believing he is superior to him) || At least Building+
Durability: At least Building (Haku commented Sasuke's katons are not strong enough to melt his ice, which were Building levelin the start of the series) || At least building+ (Blocked simultaneous kicks from Guy and Lee with just his arms, Immortality as an Edo Tensei summoning makes him hard to kill)
Speed: At least Supersonic (Outside of his Mirrors he should be comparable to Base Naruto), At least Hypersonic+ with his Crystal Ice Mirrors Jutsu (Able to completely blitz Base Naruto to the point where Naruto couldn't even see Haku move, Faster than Zabuza who kept up with Kakashi. Was fast enough to come in between Zabuza and kakashi, wehere the later was going to stab him,even though he was several meters away from them, took Sai and Kankuro by surprise, blocked a kick from Guy and Lee), Hypersonic+ with Crystal Ice Mirrors (Faster than Zabuza with his Crystal Ice Mirrors jutsu. Crystal Ice Mirrors was claimed as lightspeed and could of been legitimately this fast due to the method mentioned (reflection) being lightspeed in real life, however there have been constant contradictions where supersonic-hypersonic characters have reacted to and intercepted Haku while using this technique, making its speed an inconsistent hyperbole.)
Intelligence: High. A prodigy whom despite his young age was raised by Zabuza to be capable of taking down even jonins. Thus he also has a decent amount of experience in assassination.
Stamina: High. Managed to intercept Kakashi's blow to Zabuza, despite Haku himself already being nearly ko'd from the damage inflicted on him by Kyubi Naruto's attacks. || Nigh Limitless in his Edo tensei form
Standard equipment: Needles, kunai, shuriken, anbu mask, thick robes.
Keys: Part 1 || Shippuden
