Kirby: Planet Robobot screenshot
The Big Propeller is a grey robot with a smile, small eyes, and two orange propellers on the head. When angered, its bottom extends into a massive jaw filled with sharp teeth. Its eyes are purple.
Big Propeller appears in Stage 2 of Resolution Road and Stage 3 of Gigabyte Grounds, as well as the Goal Game. When it sees Kirby piloting Jet Robobot Armor, it becomes enraged and chases him, even crossing planes if necessary. If the enemy touches the hero, it explodes violently. Kirby can defeat it with a few shots from his Jet Robobot Armor.
