Mechon M71

The Mechon M71

The Mechon M71 is a boss in Xenoblade Chronicles. It is a Mechon, and is fought at level 18 in Spiral Valley on Bionis' Leg.

The Mechon M71, commonly referred to as the Tentacled Mechon, is a small creature that manipulates about a dozen tentacles both to move about and attack. It is a servant under Xord who was going to collect, and likely eat, Sharla and Juju after it captured them.


Similar to other Mechon, it is covered in blue and gold armour, though this particular variation seems to have a green tint to it. The M71 uses three legs to assist in keeping it firmly on the ground, as well as several tentacles that are apparently of infinite length. Its four eyes are reminiscent of a spider, although it is more accurate to call it a squid.

Three or four tentacles will assist Mechon M71 during the first stage of the battle. They lack any real firepower, other then the aptly named Fire Shot art.


When Juju runs away, he is captured by the Mechon M71. Seizing him, it awaits the Monado's wielder (presumably under Xord's orders) and faces them at Spiral Valley on Bionis' Leg. After a battle, it moves up to a stone table that acted as the roof of the cave they fought in and awaits them once more. This time, Shulk is able to kill it and rescue Juju. Xord then makes his grand entrance.
