We Can!

"We Can!" is the 19th opening for One Piece and the 5th opening for the second half of the series.

Opening
The opening begins with a silhouette of the Straw Hat Pirates before the camera focuses on Luffy putting on his straw hat and rushing forward, followed by the rest of his crew. Zoro, Usopp, Nami, Sanji, Chopper, Robin, Franky, Brook and Luffy are posing with their name board (in Brook's only his face is shown and his name is written as "The SK Brook") before the entire crew stand together as the logo flashes around.

The logo fully appears as the Thousand Sunny sailing on the open sea. Luffy is sitting on the ship figurehead as Brook starts performing for the crew. The opening then shows the Straw Hats standing in a circle witnessing many poneglyphs around them as Robin watches in amazement. Cut to Gol D. Roger and Shanks standing back to back, and flashes of the four Yonko, the current Shichibukai, and the Eleven Supernovas minus Luffy and Zoro.

Cut to Luffy, Usopp, and Chopper having a water fight as Nami, Robin and Franky sit nearby. Franky then joins Usopp and Chopper using his shoulder cannons to spray Luffy into Sanji and Zoro who start to bicker and fighting among themselves as Franky and Chopper chase Luffy and Usopp. Brook is then shown ecstatic as Nami and Robin (using her Devil fruit abilities to hold multiple water pistols) prepare to join the fight.

Cut to the Sunny sailing on a stormy sea next to an unknown island where the Beasts Pirates are marching forward. Luffy stands in an open rocky area and is joined by the rest of the crew, ready to fight, with Luffy charging ahead. The Straw Hats are then fighting the member of the Beast Pirates as Sanji and Zoro team up to fight Jack in his mammoth form as Luffy attacks Kaido before activating Gear Fourth and clashing fists with the Yonko.

Cut to a shadowy Zunisha walking the seas, Wanda riding Wany with Luffy and Carrot to the Right Belly Fortress during an eruption flood, Capone Bege and a shocked Sanji conversing inside the former body before Sanji tosses Nami, Chopper and Brook outside, Inuarashi and his three musketeers using Electro, Nekomamushi and the Guardians, Momonosuke, Kin'emon, and Kanjuro standing under the Kozuki Family crest, and the whale tree on Zou.

Cut to the Straw Hat Flag in the wind and the Crew smiling as the song ends.
