A highly versatile combat droid created by Dr. Eggman based on data from Emerl. Like the Gizoid on which he was based, G-merl learns new skills through combat situations and - in typical Eggman fashion - can be equipped with a large array of attachments. Sonic and co, as per usual, managed to defeat the endlessly evolving machine and the hull was lost at sea. Some time later, Cream discovered the nonworking remains washed up on a beach. After some tweaking, Tails managed to restore the broken robot who seems to enjoy his tranquil new life as one Cream's many playmates.

:: G-merl's transformations ::

Egg Ball No.2 エッグボールNo.2 Boss of Sunset Hill. Spin Attack: Eggman rolls speedily around the circular arena. Hopefully he didn't have a big lunch. :: Sonic Advance 3 Egg Chaser エッグチェイサー Boss of Twinkle Snow. Eggman chases your mascot of choice up a tower sprinkled with platforms: the platforms shake loose and fall shortly after contact, so leap fast and try to time your landings so that the fallen platforms smack the Chaser's cockpit. Iron Snake: Eggman periodically slings this mace on a chain to throw you off your platform-hopping groove. :: Sonic Advance 3 Egg Cube エッグキューブ Boss of Toy Kingdom. Eggman's cube inches slowly along the ground: don't let him push you over the edge. Big Missile: G-merl transforms into a giant missile and slams into the ground. iron ball attack: G-merl transforms into an iron ball and scrapes the floor of the arena as Eggman reels him back in. Surprise Attack: G-merl springs jack-in-the-box style from the top of the cube. Guardon Attack: A trio of Guardon toy soldiers springs from the cube. :: Sonic Advance 3 Egg Foot エッグフット Boss of Ocean Base. Foot Press: Eggman floats around above and slams down into the ground when anything squishable wanders below. Sonic Boom: When nothing squishable is beneath, Eggman slams down anyway and sends a shockwave across the floor. :: Sonic Advance 3 Egg Gravity エッググラビティー Boss of Chaos Angel. Eggman rolls along the shaky center bridge: use the chutes at either end to change the gravity and walk on the opposite surface. Crazy Attack: Eggman corkscrews around the bridge, sweeping both surfaces at high speed. Hopping Stamp: Eggman takes a leap to whip scuttering critters off the wobbly bridge. :: Sonic Advance 3 Egg Hammer 3 エッグハンマー3 Boss of Route 99. Big Hammer Attack: Eggman wiggles around in the middle of the arena and slams into the ground with the hammer-like cockpit, an attack that seems like it would rattle him as much as his opponent. Hammer Press: Stand on the Hammer's base and Eggman slams straight down into you from above. :: Sonic Advance 3 Egg Pinball エッグピンボール Boss of Cyber Track. Killer Ball: Eggman pootles around the bottom of the arena beneath the platform, spouting blue balls the whole way. Smack the balls with a spin to change their color and send them back at the pinball shooter. :: Sonic Advance 3 Hyper Egg Robo ハイパーエッグロボ Boss of Altar Emerald. Eggman looms over the Master Emerald, knocking back all attackers with G-merl's large, disjointed hands. Arm Press: G-merl's hands slam into the platform, ripping out chunks and leaving large gaps. Arm Ball: G-merl plays Pong with himself, juggling slow-moving orbs between each hand. Arm Catch: G-merl plays some brutal patty-cake with whoever happens to be standing between his mighty clappers. Arm Punch: G-merl's hands fire like rockets across the arena. :: Sonic Advance 3 Ultimate G-merl アルティメットジーメル Boss of Nonaggression. G-merl's ultimate form, extremely powerful but totally out-of-control. It takes the combined efforts of Super Sonic and Dr. Eggman to disable the rampaging mecha brute. W Missile: Bulky, powerful missiles. Meteor Beam: A powerful laser beam. Cyclone Attack: A whirling vortex attack with all 4 prongs extended. Thunder Beam: Electrifying laser beams that freeze Super Sonic in place. :: Sonic Advance 3
