Ragnarok

Ragnarok (ラグナロク) is a satellite cannon from Mega Man Zero 4 that Dr. Weil developed and attempted to use to destroy Area Zero and thus 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. In order to ensure that Ragnarok was completed, he deliberately left the details of Ragnarok vague to his enemies, and also had each of the Einharjer Eight Warriors lead a different front on Area Zero (A mobile particle cannon targeting Area Zero for Heat Genblem, infecting a nearby ancient machine city with a computer virus as a means to make it a frontline base for Area Zero for Popla Cocapetri, incinerating Area Zero with an overloaded Artificial Sun with Sol Titanion, pouring acid rain to Area Zero via a flying fortress with Pegasolta Eclair, using a massive electromagnetic generator to disrupt the overall area with magnetic waves with Mino Magnus, having a fake jungle overtake the natural environment of Area Zero via plant nanomachines with Noble Mandrago, reactivating an old laboratory containing potentially dangerous and uncontrollable experiments with Fenri Lunaedge, and having a drill-equipped submarine drill down to a fault line in the ocean and then detonate with Tech Kraken), as a means of both destroying Area Zero without the need of Ragnarok, and to distract the Resistance and the Caravan until Ragnarok is completed.

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.

Etymology
Ragnarok is foretold battle and event in Norse Mythology where the Norse pantheon will end up killed, and the world undergoes several cataclysmic events before sinking underwater and reborn anew, a name rather fitting for a satellite designed to destroy large areas from orbit.
