Ragnarok

Ragnarok (ラグナロク) is a satellite cannon from Mega Man Zero 4 that Dr. Weil attempted to use to destroy Area Zero and turn every place outside Neo Arcadia into wasteland. This would have left all under his control in Neo Arcadia without a place to escape from him.

On December 16, Craft used Ragnarok in an attempt to kill Weil in Neo Arcadia, destroying the tower Weil was in and causing over 20,000,000 casualties. Craft also had Ragnarok charge up for a second attack, although he aborted it when he fought Zero. After Craft's death, it's shown that Weil survived. He alerts Ragnarok's activity by firing a shot again, and attempts to use Ragnarok again, this time by crashing the satellite into Area Zero to destroy it. However, this attempt was sabotaged by Zero when he confronted Dr. Weil. The madman fused with the station's core to battle Zero, but Zero manages to defeat him, destroying the station in the process. Zero perishes/disappears in the explosion, thus ending the Mega Man Zero series.

Ragnarok as well as Weil serve as the main 'enemy' as Biometal Model W in Mega Man ZX and its sequel, Mega Man ZX Advent. In the latter, all of the remaining fragments of Model W merge together to create Ouroboros, which bears a striking resemblance to Ragnarok.
