Craft

Craft (クラフト) is a boss from Mega Man Zero 4 that is fought twice by Zero. He was a old friend of Neige, and is the commander of the Einherjar Eight Warriors, which works for Doctor Weil and has the objective of destroy Area Zero. He was once a soldier of Neo Arcadia.

MegaMan Zero 4
He first appears in the second stage, where he and the eight warriors are introduced. After defeating four of the Einherjar Eight Warriors, Craft goes to Area Zero and fights against Zero to capture Neige. He captures Neige to protect her, as Weil plans to destroy the local. When Zero goes to rescue Neige from the prison, Craft and Weil appears, but Neige and Zero manages to escape, and Craft has doubts about the actions of Weil and Neige. After the defeat of all Einherjar Eight Warriors, Craft betrays Weil and uses the Ragnarok to attack Weil and Neo Arcadia. However before he can fire it again, Zero arrives and battles him as a second attack would be deestating. Zero defeats him, and before collapsing, he says he can't face Neige after what he did, and, in his last breath, he extracts a promise from Zero that is similar to X's in the last game, as well as to leave his body in Ragnarok.

Personality
Craft said that he loved Neige and promised to protoct her, which is why he kidnapped her. In the beginning of the game, he followed Dr. Wiel because he had all the world's energy in his grasp. He didn't believe anyone could change the world. Throughout the game, he experiences a change of heart. Inspired by Neige, he rebelled against Dr. Weil and used Ragnorok in an attempt to kill him.
