Reitou Kyojin

Reitou Kyojin' (冷凍巨人, Freezing Titan)'' is the ultimate jutsu of the Kanpa, a kinjutsu of great power. The masters of ice take their abilitites to the next level with this technique. Channeling their ice chakra and releasing it in huge amount, they can construct a large titan of ice, different in structure for each user. This being does their will, leaving destruction in their wake. This technique is very taxing however, as seen when Sora Kanpa used it to decimate the incoming Kaguya masses, and was forced after about 15 minutes to a half an hour, to resort to pure Kenjutsu, to defeat the Kaguya Clan Head and stop the Civil War.

Advantages
Provides protection for the user, as the titan virtually cannot be toppled. They are quite the size, maybe as big as a Tailed Beast. They have sheer physical power, the likes of which scare most shinobi. They can plow down trees with a simple flick of the finger. Weapons created from this jutsu are unbreakable, except by a large scale Earth Technique. The Titans are relatively quick, faster than the average man, and their eyesight is so much better, allowing the user to better their vision of the battefield.

This titan is not only known for its physical prowess, but for its nature prowess as well. They are masters of Ice Release, being able to freeze people with a flick of their risk, with Mass Freezing, as well as just by looking at them with a Freezing Stare or blow a gust of frost, freezing everything that makes contact. They can freeze bodies of water, and create humongous constructs of ice against a foe, including their weapons. A Ice Release Dome or Wall created by this proved to be stronger than the Kaguya's famed drill, as well as a forceful, oneshot Earth technique. Ice Release is mutliplied tenfold with this technique.

Disadvanatages
This jutsu can be melted down by powerful Fire, Blaze or Lava Releases, as well as broken through with very powerful Earth or Dust Release techniques, however the former makes a huge wave of water to cascade, and the latter, creates dangerous ice shards that could impale the uncareful person. Also as mentioned before, it can't be used for more than a half hour, unless the user is continuely supplied with chakra. If the technique is held for the whole 30 minutes, their ninjutsu is impaired for sometime, up to two hours.
