Sephiroth's father

[Serapy]

If Hojo wasn't a scientist, that would thicken the possibility of Vincent being the father. He could have tested the Jenova cells and all of a sudden, he just found out that Sephiroth's DNA have matched his.

However, Hojo was crazy at almost most of the time so there's a possibility that Hojo tried to be more arrogant by claiming that he is Sephiroth's father. Hojo trying to deceive us into thinking that he's the god.
