Headbutt

After entering his four-tailed transformation, Killer Bee uses the two chakra horns that protude out of his chakra cloak to headbutt the opponent.

Trivia

 * As with many of the techniques of Kumogakure ninja, this technique has an English name given kanji that somewhat match the pronunciation. Usually, the kanji would be pronounced as Atama Hattō.
 * Like Killer Bee's Lariat, this technique is also called Killer Bee's eighth sword. Both techniques involve Killer Bee using the Eight-Tails' chakra to form horns.
