Biot is the home world of the Manhunters. Because of this, it is off-limits to the Green Lantern Corps. It played a significant role in the Millennium event, and has recently been used as a base of operations for Cyborg Superman.
Biot was the phrase the Yuuzhan Vong used when referring to their biotechnology.
The Yuuzhan Vong insisted that their technology not be referred to as such, since technology had mechanical connotations for them.
One example of these living servants of the Yuuzhan Vong Empire were the divination biots used by the Priest caste and their seers who used these creatures as a means of determining the future under the dictates of their religion.
The term "biot" was originally coined by Arthur C. Clarke in his 1972 novel Rendezvous with Rama, as a portmanteau meaning "biological robot." The biots reappeared in the sequels two decades later, Rama II, The Garden of Rama, and Rama Revealed, as well as the Rama computer game.
