I was doing some reading on that, and one nifty thing about said twist.

Evox has been voiced by the same actor as Venjix this entire time, hidden behind some sound editing and using a fake name for the credits.
This was set up and planned from the beginning. Well done, Hasbro.

EDIT: and I would highly advise that if you do not want to be spoiled, do not visit rangerwiki at all, on any page, for any reason. There's spoilers in places you wouldn't expect and telling you how to avoid it would be a spoiler in an of itself.
