The Death Egg Robot sentinels are designed after the original Death Egg Robot, but several times larger, being over three times the size of an apartment building. They have egg-shaped bodies with a narrow pelvis each, stubby and heavily armored legs, thin arms with cone-like forearms, thick gauntlets, cap-shaped shoulders attached to bars rather than sockets, three straight spikes for fingers and jet packs on their backs. They also have triangular markings on their chest (which are similar to those on Eggman's original jacket) and dome-shaped heads. Unlike the original robot though, the faces of the Death Egg Robot sentinels are almost blank, with the exception of a single red eye and a red field for a mouth. They are also completely gray and black with glowing red outlines.
Game appearances
Sonic Forces
In Sonic Forces, the Death Egg Robot sentinels became a staple in Dr. Eggman's army after he captured over 99% of the world. In this game, the Death Egg Robot sentinels appear in the background of Urban themedstages, namely Ghost Town, Park Avenue and Sunset Heights. In those stages, the Death Egg Robot sentinels can be seen fighting the Resistance's forces and devastating the area.
At different points in the story, the characters will be fighting the Death Egg Robot sentinels so that the player can focus on reaching the goal. One of these points is at the beginning of Red Gate Bridge, where a Death Egg Robot sentinel tries to attack Sonic and the Avatar, destroying the bridge that they trying to cross. During the subsequent sequence that plays, Sonic and the Avatar will land on a ledge, face to face with the robot. By completing the first Real-Time Interaction here, the Avatar will swing Sonic and themselves away from the robot using their grappling hook as it punches the ledge. Sonic and the Avatar will then swing around the robot while it fires its eye laser. Once the duo is in front of the robot's eye, the player must complete another Real-Time Interaction. Sonic and the Avatar will then charge their respective Spin Attacks and shoot through the Death Egg Robot sentinel's eye and head, destroying it.
In Team Sonic Racing, a Death Egg Robot sentinel appears along the Frozen Junkyard race track. Here, the Death Egg Robot sentinel is embedded in a huge glacier. Every now and then however, it will shoots two laser beams from its eyes down on the road below. These lasers will then move along two of out six orange-glowing lines that are burned into the road; if the player touches these lasers, they will take damage and spin out temporarily. Should the player make it past these lasers, the players will jump into the loop contained within the Death Egg Robot sentinel. After passing through this loop, the player will then reach the finish line.
Besides Frozen Junkyard, a Death Egg Robot sentinel also appears on the Dark Arsenal race track. This robot appears in the center of the track and is under construction. Under its arms are two Bumper-based trampolines that the player can use to take a shortcut. However, the player has to watch out for the burners that occasionally ignite under Death Egg Robot sentinel's arms, which can knock the racers into the abyss.
Powers and abilities
Due to their sheer size, the Death Egg Robot sentinels are incredibly strong and tough; one unit can easily topple buildings single-handed and withstand a barrage of shots from a number of laser turrets being fired on it from various angles by Resistance forces.[1] They can also fire powerful lasers from their eyes.[3]
Weakness
The Death Egg Robot sentinels' eye sensor are weak to direct hits, which Sonic and the Avatar exploited during their encounter with one of them at Red Gate Bridge.
