Demon General Jack McEnda IV.
That was the name of the most powerful Demon General of Gozon, under the rule of Demon King Ginaroad.
He was a Level 1000 ArchDemon who was a tiny little bit away from exuviating and surpassing Transcendence.
When he stepped into Aidos 1000 years ago, havoc followed.
50% of the Aidosian Transcendents who died in the war were all killed by this one man. He alone killed nearly 500 Transcendents.
Let's not talk about how many thousand Sovereigns and Legendries perished to his powers of darkness.
Eventually, 'Dragon Lord' Gorm Saenni had no choice but to step up and confront McEnda IV as the man's actions had diminished the Aidosians' morale and forces.
McEnda IV also had similar thoughts towards Gorm, as the Dragon Lord had left a trail of Peak Rank Demon Corpses wherever he went.
