Super Eggrobo Z

Super Egg Robo Z (スーパーエッグロボZ)

Cut through all of Eggman's recycled boss machines to face off against the (also recycled) final boss of Sonic Advance 1. The Super Eggrobo Z stands menacingly (but totally immobile) at the right edge of the arena. He'll fire off his arms like projectiles, but they're easily avoided and can be destroyed with 6 smacks a piece. Use the rising platforms in the middle of the arena to reach the Robo's vulnerable head, but time your attacks so as not to leap smack into his giant eye laser.
