Jabberwock

The Jabberwock (ジャバーウォック, Jabāuokku), also known as the Machine Dragon King (機竜王, Kiryūō) due to believing to rival the power of an actual Dragon, is an ancient machine that was discovered by Hakase during a excavation in the ruins of an old civilization within Bellum. It took a span of eight long years for Hakase to fully rebuild and complete Jabberwock, stronger and better than before. It was then given the name Ancient Dragon-type Armament: Draco ex Machina (古龍型武装・ドラコ・エックス・マキナ, Koryūkei Busō: Dorako Ekkusu Makina; Latin for "Dragon from the Machine"), being identified as a part of Hakase's Armament Series (武装系列, Busō Keiretsu lit. Armed System), despite not being her own original creation.

It is stored within the depths of Hakase's lab, provided by the Magic Council and functions as one of their secret weapons, alongside the likes of Etherion, used only when no other choice is left. As such, is very rarely employed, due to Jabberwock requiring enormous quantities of Eternano to fuel it. It is considered second to Etherion in terms of raw destructive power, due to the strong belief Etherion is the most powerful weapon the Magic Council has access to.
