Jenova raids when?

[Fyrebrand]

Nael van Darnus was essentially Sephiroth (grey hair, wields an unusual weapon, is a high ranking supersoldier that went insane, summons a 'meteor' - even had a 'walking into the flames' scene).

Zenos kinda has his own Sephiroth vibe going on as well. He even started off as a katana boi.
