The Egg Pawn (エッグポーン,Eggupōn?) is a recurring robot created by Dr. Eggman. They come in different varieties, each having its own unique abilities, and serve as Eggman's foot soldiers that attack Sonic in the games. The Egg Pawn also shares more than a passing resemblance to Eggrobo.
The Egg Pawn model first debuted in Sonic Heroes. They serve as the most common enemy in the stages and also may come equipped with a lance, machine gun, or laser. Some of them have shields that can come in three different styles: rock, metal, and heavy metal. The silver ones in the heavy armor are known as "Socio Pawns" and require a Power character to defeat. Egg Pawns carrying lances will charge you while the ones wielding lasers and machine guns will fire without changing position.
Shadow the Hedgehog
The Egg Pawn appeared again in Shadow the Hedgehog, where they work on Dr. Eggman's side in the war against the Black Arms and in the doctor's hunt for the Chaos Emeralds. In this game, they also wield weapons which can also be used by Shadow. They can be picked up from defeated Egg Pawns.
Egg Pawns also serve as enemies in Sonic Rush. This time, they had different color schemes to match the weapon (or, in some cases, no weapon) they carried. Unlike in this game, they're powered by animals. They also seem to run much faster in this game.
Sonic Rivals series
Egg Pawns return in both Sonic Rivals and its sequel Sonic Rivals 2as enemies. They are unarmed but merely damage the player by simply charging into them. Their artwork from Sonic Heroes are also seen as collectible cards.
While the Egg Pawn did not appear in Sonic Unleashed, a new type of enemies called Egg Fighters appeared in their place. These and its variants seem to be the equivalent to Egg Pawns as they bear a similar appearance, abilities and functions. Egg Fighters with a similar coloration as Egg Pawns appear in Apotos Act 1.
The Egg Pawns also appear in the Wii and DS exclusive Sonic Colors as common stage enemies as seen in gameplay trailers. Like in Sonic Heroes, their design is different based on every level. They also have a slightly different appearance -- their arms have a different color, and they are bulkier.
Egg Pawns make an appearance in Sonic Lost World. During the game, it turns out that all of Eggman's robots, Egg Pawns included, got hijacked by the Deadly Six. Egg Pawns have received a slight, simplified redesign in the game. No different variants besides regular Egg Pawns are seen in the game, though there are two types of Egg Pawns, which either stay on strings waiting for the player, or can start chasing the player around the act.
In Sonic Lost World, Egg Pawns can be found at Silent Forest, where they can pop out from small holes at the tubular stage and start attacking. They are later seen as guards at Frozen FactoryZone 3 with Crawls.
Egg Pawns also appear in Sonic & Sega All-Stars Racing where they act as obstacles. They usually move around on certain parts of racetracks, and jumping around. If a racer hits one, he/she will spin out. If a racer boosts right into an Egg Pawn, it will be gone for a few seconds before coming back. They are seen in Casino Park and Final Fortress racetracks.
The Egg Knights are gold-plated Egg Pawns that typically wield lances and lead a small group of Egg Pawns. They have more stamina than ordinary Egg Pawns and are usually found in positions where it is difficult to reach them without alerting any regular Egg Pawns nearby. This is because the destruction of an Egg Knight will result in any and all Egg Pawns in the nearby area being automatically destroyed with it.
These are-casino themed Egg Pawns that appear in casino-themed stages. There are three variants known such as the neon blue Casino Managers with black tie suits, neon pink Casino Bunnies, and neon green Casino Clowns that have weird meters above their heads, and typically wield the same weapons that the regular Egg Pawns can wield. They appear in the fifth and sixth stages and third boss of Sonic Heroes (Casino Park, Bingo Highway and Robot Carnival respectively).
In Sonic Heroes, there was also another enemy known as the "Flapper". These enemies look similar to Egg Pawns, except they fly. Again, they were featured in Sonic Rush and they also appear in Sonic and the Black Knight as enemies in the Legacy missions.
Weapons and Equipment
The Egg Pawns' weapons vary from game to game. In Sonic Heroes, they wield machine guns, single-shot cannons and lances. In Shadow the Hedgehog, they carry semi-automatic blasters, bazookas and lances (they use the same models from Heroes). Egg Pawns in Sonic Heroes sometimes carry shields which can be either rectangular, round with spikes, or stone. In Sonic Heroes, Egg Pawns that used machine guns typically angled their shots downward and fired in a sweeping motion, while in later games they shoot straight.
In Sonic Colors, they have different weapons depending on the stage they appear in. For example, they wield whisks in Sweet Mountain, pickaxes in Planet Wisp, and katanas in Aquarium Park. In a handful of stages, they can also use blasters and various other weapons.
