Craft (クラフト) is a boss from Mega Man Zero 4 that is fought twice by Zero. He was an old friend of Neige, and is the commander of the Einherjar Eight Warriors, working for Doctor Weil and has the objective of destroying Area Zero.

Mega Man 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 appear, but Neige and Zero manage 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 devastating. 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
He appears calm, controlled and loyal to Dr. Weil. Craft said that he loved Neige and promised to protect her, which is why he kidnapped her. In the beginning of the game, he followed Doctor Weil because he had all the world's energy in his grasp. He had a crisis of faith and thought that the dismal state the world was in couldn't be changed, even by heroes, which he believes are now a thing in the past. However, throughout the game, he experiences a change of heart. Inspired by Neige, he rebelled against Dr. Weil and used Ragnarok in an attempt to kill him.
