Wester is a black orb with yellow eyes, blue feet, and white hands. It wears an orange bandana across its face (which covers the lower half of its body) and a red fedora with a blue bond on its head. Wester wields a whip similar to Whip Kirby's.
Wester first appears in Stage 1 of Gigabyte Grounds and reappears in many stages thereafter. It walks back and forth across the ground, occasionally stopping to attack if Kirby draws near. It either spins its whip around before cracking it forward or leaps into the air, performing a Whip Tornado.
Wester can jump from a background plane to the foreground plane using Whip Tornado, but cannot return to the previous plane using this technique.
Wester's name is a shortened form of the word western, a reference to the enemy's design.
