And what about the Wampa? His/her character was never really given a proper introduction, or any development !

There was a series of deleted scenes that revealed that the Wampa and the Tauntaun were former lovers that were torn apart by their opposite stances on the war...and a heartbreaking scene where the Wampa finds the Tauntaun after Luke slept in it, and the Wampa cries huge Wampa tears before crawling in the Tauntaun to stay warm overnight, and then the Wampa eats the Tauntaun in the morning...crying the whole time.
