Blissenobiarella, known informally as Bliss, is a character in Isaac Asimov's Foundation series. She is from planet Gaia, and she appears in the novels Foundation's Edge and Foundation and Earth. Bliss is first introduced in Foundation's Edge as the escort for two Foundation men, Golan Trevize and Janov Pelorat, to be received to Gaia. Bliss, like all Gaians, has an enormous affinity for life and can't bear to see life destroyed. She is for long distrusted by Trevize while his partner Pelorat is quickly fascinated, until they become lovers. In Foundation and Earth, Bliss leaves Gaia with the two men helping them in their search for Earth. Trevize suggests that Bliss could be a humanoid robot, but she always denies this allegation. Indeed, it is known that R. Daneel Olivaw built many humanoid robots, one of them being Dors Venabili, Hari Seldon's wife, and sent them in the Galaxy to help him in his work of protecting humanity. It should also be noted that Bliss possessed mind control powers similar to those of Daneel Olivaw. Golan Trevize has suspected Bliss of not just merely being a Gaian, but a Robot like Daneel.
