One Piece (1999)

Season 10: Episode 373

Oars recovers from Nightmare Luffy's attack. However, the Strawhats all get back on their feet, from Luffy to Brook, and launch a final devastating attack on Oars, which ends with Luffy smashing a Gigant Bazooka into Oars' face from above, breaking his spine and finally defeating the demon. Moria, however, gets out of Oars' stomach moments later, and prepares himself for his ultimate technique, Shadows Asgard. By sucking up all of the shadows of all of the zombies on Thriller Bark, totaling one thousand shadows, Moria becomes a grotesque monster, as big as Oars in size with short spindly legs, gigantic arms, and a huge bloated neck pulsating with veins.
