I've posted it before, but here is what I would do:
- Guyot eventually uses the unit remover on Female Guyver 2, becomes an imperfect Guyver Zoalord. he will kill Balcus and Shin
- Shizu will likely die to protect Agito, knowing she doesn't have much time left.
- Apollyon fails to kill Guyot on his own and is injured.
- Sho and Agito fight Guyot and with Agito's sacrifice, Guyot is destroyed
- Apollyon takes the dying Archanphel and the Ark into space.
- Sho lives on
Whether or not the remover exists to remove Sho's unit or not I dunno... I mean our theory that the Guyver unit makes one immortal is just that, a theory.
