Egg X
From Sonic Retro
The Egg X is the seventh and final boss in Sonic Advance, which takes place in the X-Zone. This boss is protected at all times when it isn't attacking, and it has four types of attack:
- By shooting a bomb at the player (with two different angles). Jump to avoid.
- By firing a laser beam at the player. Duck to avoid
- By grabbing the player with a giant hand and then shake their rings away. Jump to avoid.
- By running towards the player.
You can only inflict damage on this boss when Eggman's cockpit is out.
