In "Foundation and Earth", Bliss leaves Gaia with the two men, helping them in their search for Earth. Because Bliss is a Gaian, she possesses considerable mentallic powers, which are often used as a plot device in "Foundation and Earth" to help her companions escape from dangers that they encounter during their quest. She commonly uses her empathic and telepathic powers to help deal with dangerous people and creatures. In addition, she also exhibits psychokinetic abilities as well as the power to help purge others of disease-causing organisms. At the climax of "Foundation and Earth" she, as an avatar of Gaia, bears witness to Trevize's explanation of why he decided in favor of Galaxia as humanity's best option for future survival.
