Fishbone D (フィッシュボーン D, Fisshubōn Dī) is the Hollow that attacks the Kurosaki Clinic on the night when Ichigo Kurosaki first meets Rukia Kuchiki. He is a humanoid Hollow with several fish-themed features. He is purified by Ichigo, who had just become a Shinigami. In the manga, he killed the little girl Plus that Ichigo had earlier protected from a group of skateboarders that had knocked over a vase. In the anime, he merely chases her and then decides to go after the Kurosaki family. Also, in the manga he grabbed Yuzu Kurosaki and attacked Isshin Kurosaki and Karin Kurosaki, while in the anime, he grabbed Karin and injured Yuzu. He also is the first Hollow seen in the manga, though in the anime, the Mantis-Hollow appears at almost the exact same time as him. Fishbone D's attack on the Kurosaki Clinic is a key event in Bleach, since it resulted in Ichigo gaining his Shinigami powers and Rukia losing hers, which was the basis of the plot of both Agent of the Shinigami and Soul Society Arcs.
