Asborean

Asboreans are worm-like creatures that wear a mobile armor resembling that of a horseshoe crab's. It attacks by sliding around along the ground, trying to collide with Samus, shooting smaller Asborean Spawn that home in clusters, and by getting up onto its hind legs and trying to headbutt or swipe.

When it moves its head back up to swipe, it reveals its glowing red button that turns out to be its weakpoint. After receiving some damage, it may poke its head out a little when sliding around, making itself vulnerable. After sustaining significant damage and becoming downed, performing a Lethal Strike will, instead of killing, rip the Asborean from its armor, left exposed and incredibly weak to sub-zero tempatures. However, if not killed immediately, the Asborean will wrap itself around Samus and self-destruct for significant damage.

The Asborean is often treated throughout Other M as a miniboss, fighting it alone with special music.

On Hard Mode, it summons an increased number of Asborean Spawn when its neck is extended, making it harder to Lethal Strike.
