Antlion Mecha


 * For the robot seen only in a Sonic CD animation, see Antlion.

Arijigoku Mecha (アリジゴクメカ) is the first boss of the Game Gear version of the video game Sonic the Hedgehog 2. It is the first Master Robot Sonic the Hedgehog faces and is fought in the Under Ground Zone. It is a robotic antlion larva with giant mandibles, and one of Dr. Robotnik's Master Robots.

Description
Its intro is unusual: as Sonic jumps the final spring, he will fall into the lava. Then, Dr. Robotnik grabs him with a claw (The same one used to kidnap Tails) and sends him to a steep valley so that Sonic will be killed by Arijigoku Mecha's jaws. Arijigoku Mecha just moves its jaws while Robotnik drops cannonballs to finish off Sonic as he avoids its jaws. All Sonic has to do is avoid the cannonballs. The cannonballs damage the antlion, and its jaws move faster. As the antlion's jaws move super fast, Robotnik charges at Sonic. If he avoided that, the Eggmobile gets crushed by Arijigoku Mecha. The chain reaction also killed Arijigoku Mecha and not the Eggmobile. As Robotnik makes his escape, Sonic leaves the valley and finds the Capsule.
