Then we are definitely looking at an interest triangle with the Guyvers, Archanfel (and his loyalists) and Guyot. If Guyot still has the Remover (and I am betting dollars to donuts that he does) he is an absolutely critical player. In the hands of a fully powered Zoalord, a Remover is the only weapon that can destroy a Guyver with certainty. But it is unlikely that Guyot can power the Remover up in his current state. Archanfel probably could, even now - if only once. But he would only need to do it once.
Now... I doubt the Remover would work on Valcuria's control medallion; Leaves Sho and Agito; and of course Guyot would prefer to remove Agito from the board, for personal and practical reasons.
If Archanfel could get his hands on a functioning, dormant G-unit... he could make all his dreams come true. It might even be a best-case scenario: he leaves Earth, the Ark with a million loyal Zoanoids (even if the full truth were revealed, I bet you could get a million volunteers from all over the world) in tow, leaving the rest behind.
Unfortunately we also have Apollyon, in whose best interests it very much is to ensure Archanfel, nor any other Zoalord, gets his hands on a G-unit. (I wonder what the Remover would do to Apollyon? The Remover deletes user data from the control medallion, and Apollyon's armor is made from the same stuff...) Plus whatever is coming from space...
