seaborn (arknights)

Non-human lifeforms born of the ocean, initiators of the Profound Silence. They have a very short evolutionary cycle to deal with hostile creatures and the environment. To this day, they continue to threaten Ægir and the coasts of Iberia.

The Seaborn are hyper-adaptive aquatic creatures hailing from the abyss of Terra's oceans. They evolve incredibly fast and possess the ability to mutate their own somatic cells without relying on generational heredity.
