DiZ

DiZ (Darkness in Zero) is a form taken by Ansem the Wise in Kingdom Hearts: Chain of Memories, Kingdom Hearts: 358/2 Days, and Kingdom Hearts II. He took this identity after being banished by his apprentices (Xehanort, Braig, Dilan, Even, Aeleus, and Ienzo) some time ago.

Kingdom Hearts: Chain Of Memories
Truly an enigma.

DiZ appeared before Riku in the guise of Ansem, presenting him with choices regarding the darkness within his heart.

It is said he and the king have met.

Kingdom Hearts II
An entity shrouded in mystery.

Kingdom Hearts: Chain of Memories
Ansem made his debut as DiZ here as an ally to Riku in his fight against Xehanort's Heartless. He aided him by giving Riku advice on the Heartless's nature as well as giving Riku and King Mickey the Organization's coats in order to protect them from darkness. He also came to Riku at the beginning to awaken his dark powers and introduced him to Naminé.

Kingdom Hearts: 358/2 Days
DiZ also appeared in 358/2 Days as the sleeping Sora's overseer, recieving progress reports on him from Naminé.

Kingdom Hearts II
In Kingdom Hearts II, DiZ also served as Sora's and Roxas's overseer. After Sora awakened, he seemed to disappear, not to be seen again until the final battle at The World That Never Was. It was here that he was revealed to be Ansem the Wise.

Appearance
As DiZ, Ansem dons a very complex outfit. His face is covered in red bandages, save for his right eye and mouth, and he tied two intersecting belts around his head, one passing over where his left eye should be. He wears a long, red cape with an odd, angular cut taken out at the chest, the edges of which are yellow. This cut exposes a similarly oblong white symbol on a pitch-black shirt. Overtop this shirt, DiZ wears what sems to be grey, segmented armor over his sides and abdomen. His legs are covered by a long, black cloth lined with yellow, which itself has several brown straps pinned onto the front, seemingly for no purpose other than to create yet another angular pattern.

On a yellow sash that hangs around DiZ's waist are three brown pouches, descending downward diagonally on his left hip. These puches are all identical, all sporting the same design on the top flap, and all closed by a darker brown strap that attatches to a silver button on the right ride, a grey tassel hanging from each button. Like Ansem and his coat, DiZ wears a dark colored scarf around his neck. He also has light colored sleeves.

Notably, as DiZ, Ansem's skin is much darker, and his beard is not present, despite his chin being clearly visible. When he removes the bandages, however, these changes disappear, suggesting that Ansem artificially changed his appearance to avoid detection. His eyes appear to be a much darker shade of amber orange when he is not in the DiZ persona, but this is likely an optical illusion caused by the extreme difference in skin color of Ansem and DiZ.
