Eggman Mech

The Eggman Mech is a boss that appears in Sonic Boom: Rise of Lyric. It is a large battle mech built and used by Dr. Eggman. However, it was not designed and created by Eggman, but he had rather acquired its parts and instruction manual from a third-party source. While physically imposing, the Eggman Mech is quite deficient due to having several construction errors.

The Eggman Mech was used by Dr. Eggman to help eliminate Lyric the Last Ancient. Due to having manual controls, it was immune to Lyric's technopathy, but proved inadequate in disposing of him. The Eggman Mech later suffered another defeat at the hands of Team Sonic, but ultimately helped save the world from Lyric during the final showdown.

Appearance
The Eggman Mech is a several meters tall humanoid machine with a primarily red coloration. It has an ellipsoid torso with a recess on the front where the Egg Mobile fits in (though its socket is loose which makes 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.

Powers and Abilities
The Eggman Machine 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 proclaimed that they were in no danger whatsoever.

The Eggman Mech is equipped with a rocket thruster on each foot, allowing to fly through the air and move fast enough to at least keep up with those riding on Ener-Rails. It also has strength on a superhuman level, capable of punching the ground hard enough to make it explode and release a powerful shock wave when stomping into 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 have poor accuracy, which makes them "sorry looking" according to Amy and 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.

Trivia

 * The Eggman Mech bears a distinct resemblance to the Big Boy mech in the Sonic Boom comic series.
