Episode 633

"A Formidable, Unknown Warrior! Lucy Appears" is the 633rd episode of the One Piece anime.

Short Summary
The episode starts with Luffy signing up for the tournament, and Franky requests Luffy to not let anyone discover who he is. Luffy was about to write his real name when signing up until Franky hit him, and now Luffy is 'Lucy', registered with the '0556' number on the back of his shirt. Luffy and Franky are separated now, Thunder Soldier looking at a board. Franky asks Thunder Soldier about the Don Quixote family, much to Thunder Soldier's surprise. Franky proceeds to ask about a 'factory'. Meanwhile, Sanji is seen with Violet, wandering around Dressrosa.

Luffy defeats Spartan after he tried to punch him several times. Luffy was about to be disqualified, until Sai broke in and stated that Spartan was the one who started the fight. Luffy thanks Sai. The Funky Brothers are arguing with Dagama, claiming he's 'forming alliances' in his block. The episode ends with Lucy searching for a new armor and Cavendish appearing, telling Lucy there is a weight limit.

Anime Notes

 * The anime adds the following:
 * A scene in which Luffy and Franky part ways inside the colosseum.
 * Franky getting acquainted with Thunder Soldier and asking him for information after the latter mentioned about Rebecca entering the tournament.
 * Thunder Soldier looks at a board showing the names of all of the notable gladiators and which block they are in. The board shows that Hera, Spartan, and Gambia are all in D Block, despite the manga not showing which block any of them were in. Also there is a mistake about Maynard's name, because he was under the nickname "Capman" like Burgess' "Mr. Store".
 * An additional scene with Sanji wandering Dressrosa with Violet.
 * After Sai stood up for Luffy, a staff member asked another gladiator if Spartan was the one who started the fight, which he confirms. Luffy also gives Boo back his axe while thanking Sai.
 * In the manga, Spartan only tried to throw one punch at Luffy. In the anime, Spartan tried to punch him several times.
 * After Spartan is knocked out, he isn't shown to be bleeding like in the manga.
 * Luffy is shown to spin Spartan several times before slamming him down, whereas in the manga, Luffy simply flipped him over.
 * Right after Spartan's defeat, shadowed images of Sai, Boo, Chinjao, Rebecca, Kelly Funk, Bobby Funk, Hack, and Ideo appear.
 * In the manga, Sai gave Luffy the middle finger as Boo dragged him away. This was censored in the anime.
 * Unlike the manga, the anime shows the beginning of Block A. In addition, the rules of the battle royale are explained prior to block A while the rules were explained during block B in the manga.
 * Bellamy simply grabs a man's head when he is introduced, whereas in the manga he was shown cruelly crushing said man's face.
