The Eggman Mech is a boss that appears in Sonic Boom: Rise of Lyric. It is a large battle mech from a third-party source which was used by Dr. Eggman. While physically imposing, the Eggman Mech was quite deficient due to several construction errors.

The Eggman Mech was used by Dr. Eggman to eliminate Lyric the Last Ancient, but proved too inefficient in battle. The Eggman Mech later suffered another defeat at the hands of Team Sonic, but ultimately helped save the world from Lyric.


The Eggman Mech is a several meters tall humanoid machine with a mostly red coloration. It has an ellipsoid torso with a recess on the front where the Egg Mobile fits in (though its socket is loose, making the Egg Mobile prone to tilt), and around each shoulder it has a spiked shoulder guard and a three-layered plating. Its arms consist of a thin, black upper arm and a much bulkier forearm with four black, grabbing hook-like fingers. Its pelvis is quite small and round, while its legs have thin black upper legs and its lower legs are bulky with yellow ankles, thrusters on its soles and a black planting for toes.



Sonic Boom: Rise of Lyric

The Eggman Mech was built by Dr. Eggman, who got its parts and instruction manual from an unspecified source. When it was finished, Eggman still had a few screws left. Having initially failed to eliminate Lyric to become the dominant villain, Eggman deployed the Eggman Mech for this task, knowing Lyric could not control it.

Tracking Lyric to Creeper Gorge (while seizing the Twilight Crystal on the way) Eggman faced him in the Eggman Mech. With Lyric incapable of taking control of it, Eggman attack him with his mech's missiles, but they all missed. Lyric thus left, mocking the doctor. Furious, Eggman noticed Tails and Amy nearby and pursued them in his mech. The chase eventually reunited Team Sonic, whom Eggman now intended to crush. However, the Eggman Mech was quickly defeated and heavily damaged, forcing Eggman to abandon it and the Twilight Crystal.

Eggman later salvaged the Eggman Mech and took it to Lyric's Lair. Just as Lyric caught Team Sonic, Eggman fired the mech's missile at Lyric, distracting the snake and allowing Team Sonic to stop Lyric for good. At that point, the Eggman Mech reached its limit and collapsed.

Powers and abilities

The Eggman Mech is a quite powerful machine, but ultimately poses a little threat to strong individuals like Team Sonic due to a low-quality arsenal and faulty construction. Even when bombarded by the Eggman Mech, Tails noted that they were in no danger whatsoever.

The Eggman Mech is equipped with a rocket thruster on each foot, allowing it to fly and move fast enough to at least keep up Ener-Rail users. It also has strength on a superhuman level, capable of punching the ground hard enough to make it explode and release powerful shock waves by stomping the ground. In terms of armaments, the Eggman Mech can fire cannonballs from the palm of its hands and launch missiles from its shoulder guard, though its missiles are refurbished and "sorry looking" according to Amy, giving them low accuracy and making them vulnerable to the Enerbeam.

The Eggman Mech is operated entirely by manual controls. As such, it is completely immune to Lyric's technopathy device in his armor.


The Eggman Mech is the fifth overall boss of Sonic Boom: Rise of Lyric and is fought with the entirety of Team Sonic directly after reaching the end of Creeper Gorge. The boss battle takes place on an enclosed round platform with bottomless pits surrounding it.

Boss guide

To defeat the Eggman Mech, the player must get Eggman's cockpit down on ground level and attack it. As long as it is standing up, the Eggman Mech is invulnerable to regular attacks and approaching it will make it try to punch the player. For the first battle phase, the Eggman Mech stays in the center while weak Destruction Troops appear and continuously respawn. In the beginning, the Eggman Mech starts out by sending out a shock wave with a stomp that covers almost the entire field, though it can be dodged by jumping over it. After that, the Eggman Mech will shoot missiles in intervals which can be dodged by moving away. Missiles that do not hit fall to the ground, though they will eventually explode.

To attack the Eggman Mech, the player must lasso its missiles with the Enerbeam and throw them back at it. After being hit four times, the Eggman Mech will be stunned, which is when the player must use the Enerbeam on it for a few seconds and make it fall over. However, should the player be attacked, they will lose grip and will have to start over. Once fallen, the player must keep attacking Eggman's cockpit until the Eggman Mech gets back on its feet.

For the second battle phase, the Eggman Mech will continue shooting missiles, though it will then follow it up by shooting five cannonballs and then fly towards the player. Should the player near it when it arrives, the Eggman Mech will try to deliver a punch. Additionally, much stronger Destruction Troops will begin appearing. Repeat throwing four missiles back at it, pull it down with the Enerbeam and attack the cockpit until it rises up again.

For the third battle phase, the Eggman Mech becomes move aggressive, attacking with both cannonballs and missiles just after it has flown towards the player. Also, whenever it lands from flying at the player, it stomps the ground and sends out the same shock wave from the first phase. Additionally, the toughest Destruction Troops will appear for this phase. Repeat the same pattern as earlier and hit with four missiles and bring it down with the Enerbeam again. Once the player is done attacking the cockpit, the battle is won.
