Bereet was a female Krylorian techno-artist who used her alien technology to produce films concerning fictional adventures of herself and the Hulk. Most of the population is obsessed with the escapist movie-like fantasies of techno-art films, leading to her popularity among her people. Bereet later traveled to Earth and became involved with the Hulk while he had Bruce Banner's intelligence, befriending the Hulk and Rick Jones. She also encountered the criminal Jackdaw. Bereet used a number of devices such as the spatial distorter, Banshee Mask, Defendroids, her "pet" Sturky, and a variety of other advanced technological devices. The planet Krylor and its population was destroyed by Ego the Living Planet during the onset of the Maximum Security crossover.
As a Krylorian, Bereet has a number of traits typical to their avian-mammalian semi-humanoid physique, including highly porous bones; a trilling, musical voice; two fingers and a thumb on each hand; two toes on each foot; red irises; and a deep pinkskin color. She uses a number of techno-art creations including her Spatial Distorter, Banshee Mask, Defendroids, Energy-Eaters, "Flitter," Insula-Sphere, Life Support Spider, "Spindrone," Star Eyes, and "Web-Spider." Bereet demonstrated a number of other techno-art creations in her movie, but it is unrevealed if she used any or all of these in the 616 reality.
