different forms of jesus

on the one hand the bible says God never changes,
i can accept that that means his appearance never changes and also his works and judgments.
but the bible says that Jesus appeared in a different form to two disciples.
the tv series Joan of arcadia implies that jesus can appear in any bodily form and does, i think because of this same verse.
however Paul also writes that jesus does not appear as a man traveling on the road which contradicts the 2 disciples testimony that it was jesus!

on the other hand there is a demon LORD Similitude in the tv series Buffy the vampire slayer which does change appearance and form to confuse and deceive all people.
Ed Dames as a remote veiwer says that holographic imagery can produce similitudes that have mass and visual experiences! he spoke of bigfoot in this example.
if jesus appeared in his resurrected body, I would Tell the world that his body does not change, that it would be the same body he was resurrected with.
that being said, however, i recall that there is a doctrine of teaching which says jesus is lord over at least 12 other planets! if this is true! Jesus might have access to 12 other resurrected bodies. which means at the same time Jesus can appear in 12 or 13 forms of body which are different frome each other.
the complexities of what happens in the eteral galaxies and the plans of salvation can be very confusing. Unless direct revelation and answers are given specifically from the presense and mouth (lips) of jesus himself.
