Sonic fighting the Egg Hornet.
After Sonic found Tails in Emerald Coast they set a meeting in Tails' workshop. When they get there Eggman showed up and ordered them to give him their Chaos Emeralds. Sonic and Tails refused and Eggman told them that he would take it from them the hard way, and thus the battle began.
It appears to be an Egg Mobile with spikes on the edges. It also features Missile Launchers at the front of the vehicle.
The Hornet attacks by firing missiles at the player. The player can dodge this attack with constant moving in different directions. The second attack pattern of this boss is charging into the player with its two drills. The Egg Hornet locks on the place where the sonic is standing and then charges into it therefore if player changes sonic's position, sonic won't be damaged. After Eggman rams the Egg Hornet into the ground it will get stuck for few moments and player can damage the cockpit during this time. After attacking the cockpit three times, the boss is defeated.
Sonic XThe Egg Hornet was also in the show, Sonic X, as one of Eggman's battle vehicles. He did battle with Sonic for a brief time until one of the drills was broken by Sonic's continual spinning. It was then destroyed but Eggman escaped the explosion with his mobile attachment.
- If playing as Sonic, the player can perform a glitch to beat the Egg Hornet after it dives into the ground. After it dives into the ground, if the player keeps using the Homing Attack, the Egg Hornet will stay in place and keep sustaining damage.
