For normal version of this enemy, see Berserk Ardun (normal).

Berserk Arduns are two story exclusive enemies in Xenoblade Chronicles. They are members of the Ardun family. They are found at level 14 at Rho Oasis in Bionis' Leg. They are fought during a story event battle while rescuing Juju by the lake.

They do not respawn nor drop Treasure Chests, although they do carry items. These items are unobtainable, however, as the Berserk Arduns appear before Riki joins the party, and Riki's Yoink! ability is the only way to obtain items which enemies carry but do not drop.

There is a normal variant at level 16. These Bersek Arduns are respawnable, they are also fought when battling the Trainer Harmelon Unique Monster.
