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 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. 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.

Trivia

 * Concept Art for Craft demonstrates different ways he could equip his weapon and wear his cape.
 * Craft went through several designs, including a younger very different Craft, who bore a close resemblance to a purple and white armored Megaman X. Other sketches also show him with a anime-like neon-green haircut.
