Lightning Release: Lariat

Three-Tailed Lariat
After having gone into his Three-Tailed form, Killer Bee will form the chakra around his left arm into two bull-like horns. He then charges at his opponent, striking them with a Lariat move. This strike is powerful enough to blow away the target's entire chest. The attack is straightforward, though, and can be easily seen through with the Sharingan. This technique is also called the, being Killer Bee's eighth "sword," next to his seven conventional katana.

Seven-Tailed Lariat
In his fight with Kisame Hoshigaki, Killer Bee entered his seven-tailed transformation. At that point, he performet a version of the Lariat that used not cloak-horns, but an actual bull's skull formed out of dense chakra bones similar to the ones found in naruto's six-tailed transformation. This version was powerfull enough to severely damage Kisame's abdomen and would have been fatal were it not for his healing abilities.
