Marrin

Marrins are an enemy species in Xenoblade Chronicles 2, Torna ~ The Golden Country, and Xenoblade Chronicles 3. They are aerial eel-like creatures with a large horn on their heads. They resemble and are possibly related to the Serprondss.

Xenoblade Chronicles 2
Serprondss can be found in Tantal and the Kingdom of Torna. Marrins can also be brought up by Rex while salvaging at certain Salvage Points.

Xenoblade Chronicles 3
Serpronds are completely unchanged from their Xenoblade Chronicles 2 counterparts.
