Chozo DNA

Chozo DNA,Nintendo Official Guide Book for Super Metroid pg. 7, as translated by MetroidLuver13 also known as blood of the ChozoSuper Metroid Chapter 4, pg. 62 and Chozo blood,Super Metroid Chapter 4, pg. 67 refers to blood that runs through the body of a Chozo. It has been implemented into at least one human, Samus Aran, in order for her body to better adapt to the harsh conditions of Zebes. Without it, she would have to have been confined to Crateria and Brinstar as these were the only areas of Zebes that were habitable to humans. This was done by placing her within a specially-created Body Adaptation Machine. Gray Voice provided his blood for Samus's adaptation, a fact she would not discover for many years.
Samus's Chozo DNA, combined with their intensive training, gives her speed and agility beyond the capability of ordinary humans, and apparently enables her to survive suitless, or at the very least helmetless on Zebes and Elysia. She is later integrated with Metroid DNA, giving her the ability to prey upon X Parasites, at the cost of being more susceptible to extreme cold.
It was later revealed that she actually carried two types of Chozo DNA, one belonging to the Thoha tribe (presumably from Gray Voice) and the other from the Mawkin tribe (from Raven Beak). The Mawkin DNA allowed for her battling prowess, inherited from the tribe of Chozo warriors. The Thoha genes also ensured that Samus's Metroid DNA did not cause her to become a Metroid immediately after the Vaccine Metroid procedure she was supplied,Metroid Dread, Nintendo (2021)ADAM (Raven Beak): It appears your Metroid DNA has . Ordinarily this would have occurred immediately after the transplant. Your must have . They were the only tribe capable of controlling the Metroids. Though you possess their DNA, you are not a Thoha. Your physical prowess suggests you must also possess . although Raven Beak's ambush destabilized this bit until Quiet Robe's X Parasite restabilized it. Both Gray Voice and Raven Beak regard Samus as their daughter due to donating their DNA.
In the origin manga, Space Pirates are seen attempting to use these machines to adapt to Zebes, although whether they too used Chozo DNA is unclear.
