I have come across many clues over the years that points to Gaiseric being the Previous egg of the king user who was born into the real world just like Griffith. He came out of nowhere to conquer the land, was called the demon king, worn a specially designed armor just like Griffith. His kingdom was fated to go down in flames by the one who would become void. Pissed off that his desire to rule, his kingdom, and everything he wanted was taken away by another godhand, He would go on and hunt apostles and Godhand. He alone would have the power to kill a godhand every 216 years, and they get replaced. The longest living godhand now which is void is next on the chopping block this time since his replacement is destined to take down Griffiths Kingdom after they raise taxes take over. From chapter 358 I suspect minister Faus to be that replacement or someone else who is overly concerned for the people in the kingdom. There are many clues tying Gaiseric to the Godhand throughout the manga
