The Creature from the Ego is a bizarre invisible monster caught on Rialto IV. He's violent, brutal, bloodthirsty, and a sucker for insincere flattery. He can be found in Cell 105 of the brig on board the DeepShip 86. Roger can hear him and sense his presence, but cannot see him. Which, according to the Narrator, is a good thing if one has just eaten. The creature does, however, visualise for a fraction of a second every now and then by running into the forcefield. He also does so when Roger talks to him and says something like "Hey, handsome! Let's see that pretty li'l face!".
