Grand Fisher

is a Hollow that had evaded Shinigami for 54 years and is responsible for the death of Ichigo's mother, Masaki Kurosaki. In the anime, he prefers to eat women, which is why he killed Ichigo's mother; in the manga, he prefers to eat children, and Ichigo's mother merely got in the way.

Appearance
In Hollow form, he resembles a giant hamster with bird-like hands and feet and a tentacle-like limb that hangs from his forehead, similar to the esca (lure) of an anglerfish. The lure is vaguely human-sized and can be transformed to resemble anyone Grand Fisher wishes, usually taking the appearance of one of his previous victims. It can act independently of Grand Fisher, and as long as either the lure or Grand Fisher himself survives, he cannot be purified.

After his defeat by Ichigo, Grand Fisher is turned into an imperfect Arrancar by Iceringer and used by Aizen as an experimental subject. In his first Arrancar form, he resembles a smaller, more humanoid version of his old self with a tattooed face. His mask remnants made up his enire lower jaw which obscured half his face.

When he appeared again in the human world again to kill ichigo howerver, his appearance changed drasstically. His entire mask was left unbroken and the upper half sat on his forehead. He also had fur all over his body and was much larger. His hollow hole was also higher than his appearance in volume 3. He carries a large Zanpakutō on his back, which is almost as tall as a two-story building. He is killed by Ichigo's father, Isshin Kurosaki. The difference of how he appeared in volume 3 and how he appeared in the human world when trying to kill Ichigo has not yet been explained. It may be related to the reason why Di Roy looks different than when he was in volume 3.

Powers & Abilities
As a Hollow, Grand Fisher's preferred method of fighting Shinigami involves using his angler to keep opponents at bay, rather than attract them as it would normally be used. By transforming the angler into a decoy copy of someone close to his enemy, he can keep them from attacking, since they will be unwilling to harm the decoy. He can also grow his hair and fingers into spikes to stab enemies, or use them to restrain an opponent. Grand Fisher explains that when his hair and claws are used as spikes to stab an enemy, they also absorb the memories of that particular enemy, hence his ability to use the lure to create a copy of their loved ones or friends and use their image as a shield. Outside combat, his angler is used like its namesake, allowing him to distinguish those with high spiritual power from common humans and devour them.

Zanpakutō

 * Resurrección: By unsheathing his zanpakutō, he transforms into a huge, monstrous creature with bull-like horns on his chest and also gains a ridge on his head. The upper half of his mask also disappears. It is in this form that his imperfiction truly comes into show, as his zanpakutō is still there, although now gigantic and unsealed.

Bleach Dark Souls
Grand Fisher is an unlockable character in Bleach Dark Souls, in his hollow form. One of the strongest characters in the game, his very powerful Hair Extension attack could cover 3 other opponents and slicing their health gauge in half or even more.
