Hey. I’m back. And I’ve been brainstorming.
First up:
Windstorm Assault: A whirlwind wraps around the forearm of the user. The whirlwind expands when the arm is thrust forward. The whirlwind is very much affected by the hand technique of the user. An open palm will create a wide, powerful twister that will push even the heaviest opponents back. Pointed fingers create a narrow, fast twister that can cut an opponent. The twister created by a fist will send an opponent spinning/flying back (think of how Rasengan affects opponents in filler arc) peeling off layers of skin and flesh, as it has both the power of the open palm and the speed of the pointed fingers, but is very difficult to control. Regardless of hand technique, hitting the ground will create tornados that move independently and if you cross your arms, they will make a double helix. The technique is most efficient if the hand actually touches the target, preferably at the maximum extent of the arm motion.
I was thinking about this while coming up for original techniques for Okuri Okami, whom, I might add, possesses the most powerful wind chakra with the exception of his Bijuu, the 7 tailed wolf. It would be extremely difficult for any mere mortal to attempt this, even someone at the Kage level. I would assume, then, although he cannot perform Windstorm Assault, Yua’s father may be able to perform a lesser feat. No whirlwind would be involved, only a strong blast of air.
Second, I have been thinking more and more about the Bijuu and any abilities they might possess. I came to the conclusion that every Bijuu does/should have an ultimate attack. For some, the attack might be very obvious (Isonade, the 3 tailed shark, can cause a massive ocean storm, causing multiple tidal waves. Sokou, the 4 tailed beast living in a volcano, can make it’s volcano erupt. Raijuu, the 6 tailed weasel of lightning, strikes an opponent with enough electricity to power an entire city for several years) while less obvious for others (Kaku, the 7 tailed badger, explodes the earth beneath his opponent, and the Nekomata, the 2 tailed cat, curses the opponent with the haunting of a thousand terrible dead spirits for all eternity). For our 3 favorite Bijuu, the ultimate attacks are as follows:
Shukaku: Supreme Sandstorm, Sea of Sand: The entire desert (and I mean the entire desert, no one spot is spared) begins to churn, and the dunes of sand begin to act like waves of seawater. The result is that the desert acts like a stormy sea, with hundreds of sand waves acting independently of each other. Shukaku can keep this attack up for several hours
Okami: Ultimate Windstorm, Polar Hurricane: Not much explanation is required. It is comparable to the storm from ‘The Day After Tomorrow.” Not only does it do major damage to the local area, but it lowers the global temperature by 1°C. As we all know, hurricanes form in tropical waters, starting out as random thunderstorms. Okami creates a thunderstorm of epic proportions using chakra, and sets it spinning. If Okami is not by the sea (and Okami is usually very far from the sea), he will obtain the moisture necessary from nearby clouds. The storm will last a week. It moves twice as fast as any naturally occurring hurricane, but its diameter is so great it takes an entire day for it to completely pass over one significant geographical area. When the storm dissipates, global temperatures will still be at their lowered measure for another week.
Kyuubi: Ultimate Firestorm, Rain of Hell Born Inferno: Again, not much explanation necessary. This is your basic ‘Apocalypse Attack’. The ground cracks up in a multitude of earthquakes, and the rocks are sent high in the sky, only to fall down again as burning meteors. Magma may rise up from deep underground chambers, and did I mention the sky is aflame? The global temperature rises 1°C (as if to counter Okami's ability to lower it), but the rain of fire will only last one day. The temperature increase only lasts as long as the burning flames.
