One Piece Episode 637 English Subbed Episode Title:Big Names Duke It Out! The Heated Block B Battle!.Episode Description:Seeing that his true identity is exposed, Luffy tries to defend himself from Chinjao's devastating headbutts and Cavendish's irrational hatred while trying in vain to convince them he's "Lucy". Luckily, Chinjao's grandsons manage to intervene and halt Chinjao's rampage before he gets disqualified. They convinced him that they should focus on the "real prize" and that since Luffy is in Block C, they can kill him in the ring without repercussions. Cavendish, however, intends to kill Luffy before the match and proceeds to hunt down Luffy, who escaped the fight and is hiding outside, hanging underneath the stands window. At the Battle Royale, only 30 combatants remain in the ring with the numbers being further reduced with the defeat of Tank Lepanto by Abdullah and Jeet who are in turn defeated by Bellamy. However, much to everyone's disgust, Bartolomeo proceeds to urinate in the water in front of the audience. Hack sees this as a vulgar display and attacks him from behind, but somehow his attack was nullified and his arm broken and bleeding while Bartolomeo remains unscathed, leaving everyone who witnessed this shocked and confused at what happened.
