Mercurian (Power Rangers)

Mercurians are a sapient mercury-based humanoid species from Mercuria.

Biology
Externally, Mercurians are normally identical to Humans. However, their bodies are truly comprised of solidified mercury rather than flesh, and they are capable of converting back into liquid mercury, in situations such as taking enough damage. In these situations, using metal stabilizers on them can revert them to their humanoid form, although they can also do so after several hours. In addition, Mercurians are capable of manipulating mercury for various purposes, including morphing their limbs into weapons. Due to their body's composition, materials that are harmful to mercury will harm them, making them appear ill.

Culture and society
Mercurians were known to operate, or at least serve in, the Intergalactic Emergency Responder Squad, an interstellar search-and-rescue organization. Under the organization, teams of Mercurians were assigned to any given disaster, and were suited for various roles, including fighting any threat present, known to carry spears with several spikes near their spearhead. Mercurians, or at least those in the Intergalactic Emergency Responder Squad, are known to wear dark grey uniforms with silver vests. The power and effectiveness of Mercurians is known throughout at least the Milky Way, and likely any other galaxy the Intergalactic Emergency Responder Squad operates in, making warlords desire them as soldiers.
