Dragomin

Dragomin is a naturally occurring growth hormone found in the blood of dragons native to Ronron Island, featured in Akira Toriyama's manga Kajika. The hormone is responsible for the rapid maturation of infant dragons after hatching. When consumed by an Earthling, it triggers a transformation into a dragon-human hybrid with extraordinary powers.

Earthlings who consume dragon blood containing Dragomin transform into a dragon-human hybrid with draconic physical features. The Earthling Gibachi consumed dragon blood containing Dragomin and was transformed into a dragon-man, a hybrid creature possessing both human intelligence and draconic physical attributes. In this form Gibachi gained considerable power that he used to terrorize others.

Dragomin originates in the bloodstream of dragons native to Ronron Island in the world of Kajika. The hormone serves a purely biological function within the dragon species, allowing newly hatched dragons to mature at an extraordinary rate and reach full adult size in a fraction of the time it would take most creatures. Obtaining the hormone requires access to the specific dragon species.

Dragomin occurs naturally within dragon biology, while Animorphaline is a manufactured drug that also transforms humans into animal-type hybrids. This distinction positions Dragomin as part of the organic ecosystem of Toriyama's world rather than a product of scientific or military experimentation. Both substances produce hybrid creatures, but their origins are fundamentally different.

Dragomin appears in Kajika, an Akira Toriyama manga separate from Dragon Ball. The hormone is part of that manga's worldbuilding around the dragons of Ronron Island. The transformation a human gains from consuming Dragomin is one of the manga's key supernatural elements.
