I want Frankenstein to kill at least 2 union elders, Frankenstein's personality is too cool, these union elders should tremble at one point when they face him whilst he is at his fullest ability. Matter of fact I want him to kill the 9th elder, 5th elder and definitely Dr. Crombell the 13th elder. I want him to kill the 13th elder so badly, because he has just been using Frankenstein's research from his diary to get to the status he acquired. So I guess its safe to say that Dr. Crombell would not have gotten where he is now without Frankenstein's Journel.
I thought it is mentioned in the latest chapter that frankenstein experimented on himself but the hatred and the power that comes from the dark spear today is because of the union's actions and experiments(deaths and suffering of countless people).
I don't think Franky have more 2000 years. He have more then 900 years but 2000 is too much. Raizel fell asleep 820 years. And Francky look like a modified human born beetwen Roman Empire and Middle Ages.
