One of the few times we see Sasuke out-classed in a ninja fight, his battle against Killer Bee was a sight to behold. But why does Sasuke fight Killer Bee?
Sasuke has to fight Killer Bee because he wants to steal his Tailed Beast. The Akatsuki agreed to tell Sasuke where Killer Bee was because he also wants to destroy the Leaf Village. If he steals Bee’s beast and the Akatsuki has Naruto’s beast, then the Leaf Village would be doomed.
The Akatsuki and Taka (Sasuke’s rogue ninja team) decided to work together out of the common interest of attacking the village’s elders.
Plot Behind Why Sasuke Would Fight Killer Bee
In chapter #404, Sasuke sits with Akatsuki members Obito and Kisame in a hidden hideout. He explains to Obito his end goal of destroying the elders of the Leaf Village for their role in manipulating Itachi.
Kisame says that even with Taka (Sasuke’s rogue ninja crew), it would still be too difficult to attack the elders head on. Those below will shield them.
Obito agrees, yet admits that the Akatsuki is low in manpower too. Since the two groups share a common interest in destroying the Leaf Village, he proposes that Taka and the Akatsuki move together.
Should Sasuke agree, the Akatsuki would be willing to share the “Biju” with them. Biju are chakra monsters which physically manifest as Tailed Beasts, such as the source of Naruto’s chakra, the Nine Tails. There are nine Biju in total and so far the Akatsuki has collected seven of them. Only Naruto’s Nine Tailed Fox and Killer Bee’s Eight Tails remain.
Both groups plan to gather the remaining two beasts and split the power between them. Akatsuki will be responsible for tracking down Naruto, and Sasuke will take Taka and find Killer Bee. Itachi and Kisame went to the Leaf Village in the past to try to steal Naruto’s beast, but failed.
Was Killer Bee trying against Sasuke?
Killer Bee was toying around with Sasuke for the beginning of their confrontation. He did not take him seriously at all, pausing the fight every few moments to write down a rhyme that came to his head.
That being said, Killer Bee was definitely trying against Sasuke later into their fight. He used the full power of his Tailed Beast and did not hold back with the strength of his jutsu. Killer Bee even ending up escaping because of the severity of the fight,
How did Killer Bee get away from Sasuke?
Killer Bee was able to get away from Sasuke by leaving a decoy in his place. Once Sasuke cut Killer Bee’s tentacle, he used a substitution jutsu to leave behind a fake in his place. Sasuke did not realize this until he brought the decoy back to the Akatsuki for the Tailed Beast extraction ceremony.
