The Egg Fighter: Knights are identical to the standard Egg Fighter model. They have a torso in the shape of a hemisphere, with four flashlights arranged in a rectangle on their front and a flat cap-shaped head on top of it. They have relatively short legs, with flat feet and circular ankles, and four-fingered arms that extend almost down to the ground. They are colored steel blue and silver, and have purple eyes.
Egg Fighter: Knights can only be found in very few daytime Action Stages. Due to possessing a sword, the Egg Fighter: Knights have a much greater attack range that the regular Egg Fighters. In gameplay, whenever the player touches the Egg Fighter: Knights' shields, Sonic will be send flying backwards in the opposite direction while leaving the Egg Fighter: Knights unharmed.
When attacked, the Egg Fighter: Knights will use their shields to defend themselves. When going on the offensive, the Egg Fighter: Knights attack with their swords, either by jumping into the air and swinging their sword down on the player or launching short dash while slashing with their sword.
To bypass the Egg Figher: Knights' shield, the player must either attack the Egg Figther: Knights from the rear or any other angle where they cannot protect themselves with their shield, or attack them with Slide. Additionally, the Egg Fighter: Knights can be attacked up front if the player strikes them before they can put up their shields.
