A naturally aggressive warrior race hailing from the planet Vegeta who are, purportedly, the strongest warriors in the fictional Dragon Ball universe.

They are able to manipulate life energy and are able to sense said energy from other living beings

Large, fierce reptilian predators native to Home. In the very ancient history of the Race, petitioners who appeared before emperors (Ssumaz dynasty or otherwise, as this was long before the planet's political unification even by the standards of the Race's history) and did not show the proper respect were thrown to sdanli as a form of capital punishment. The punishment was later changed to a nonlethal, symbolic one: courtiers in sdanli-skin masks surround the disgraced individuals and mock them.
