Blood (Earth-5875)



"Oh. My. God. You're covered in blood."

- - Janissary James to Jersey Morelli

Blood is a body fluid that delivers necessary substances through the body of animals. For humans and san'shyuum, blood uses hemoglobin to transport oxygen to the cells.

Overview
Humans and san'shyuum bleed red blood when injured, and some forerunner artifacts, such as the Menachite Complex, can be manipulated by human blood.

If a target is shot, cut, or injured without energy shields, they will bleed. The color and viscosity of blood varies between species.

In some sangheili cultures, blood holds a special significance, such as blood of the family being spilled by the hands of a son or daughter being dishonorable. Blood is also present in numerous motifs in sangheili maxims and proverbs.

Blood colors
