Episode 371

"The Straw Hat Crew Annihilated - Full-Throttle Kage Kage Abilities" is the 371st episode of the One Piece anime.

Short Summary
Moriah explains that he enabled Oars to stretch by stretching his shadow, thereby forcing his body to stretch along with it in order to ensure that the body and shadow are the same shape. Usopp fires Brook out of the Kuwagata, with Nico Robin making him spin and Nami electrifying him, but he only does minor damage to Oars and is knocked out when Oars retaliates. Robin attempts to use her powers on Moriah, but he attacks her with his shadow and then switches places with it, rendering her attack useless. He then takes her shadow, rendering her unconscious. Chopper discovers that Oars died of frostbite, and that while he does not feel any pain, he can still take damage from their attacks. Sanji and Chopper launch a combo attack on Oars, who then knocks out both of them with Gomu Gomu no Gatling Gun, leaving only Nami, Zoro, and Usopp standing.

Trivia
During the scene where some of the Straw Hats are shown knocked out and bloodied, blood can be seen on Brook's clothing. However this should not be possible as he is, as he would put it, "just a skeleton". A similar scene in the following episode fixes this mistake however.
