Why can Abe not possess Scrabs, Paramites or Glukkons in Abes Oddysee?
Notice that after receiving his Scrab scar, Abe does not encounter another Scrab until Abe’s Exoddus. Best guess is, it’s the scars that gave him the ability to possess Scrabs and Paramites. Abe did not have any opportunity to possess Glukkons in AO – in the Board Room he would have been shot, and his hands were tied up when he was confronted with Molluck, so it may be that he had the ability to possess them all along. Abe only has the ability to possess the more intelligent species – hence it is unlikely we’d see him in control of a Fleech, although that would be fun! However, Abe’s abilities are constantly developing, hence his ability to use Possession Orbs and take control of Slogs in Munch’s Oddysee.
