Ok. Starscream's Ghost appeared in G1 or something if what I read on the Wiki is correct? This is similar or the same to his disembodied Spark we saw in 'Possession' in season 1 of BW? Or something different?
Whilst he appeared as a transparent visage in G1, he appeared only as a 'Wandering-Eternal' Spark in Beast Wars, save for a rather quick flash of his G1 self in place of Waspinator during a flash of lightning , I think most people consider it to be one and the same thing.
