Sky Sanctuary Zone

Sky Sanctuary Zone, Act 1, as Sonic. SSZ marks the first time Eggrobo was seen in a Sonic game.

Sky Sanctuary Zone contains three bosses and involves a heavenly, but ruin type level in the sky that works its way upwards, chasing after the Death Egg.

The first boss is a clone of Green Hill Zone's boss.

The second boss is a clone of Metropolis Zone's boss.

Both of these bosses are piloted by Mecha Sonic.

The third boss is Mecha Sonic himself... and he's VERY easy to defeat. When he's in the corner, him him on the front part of the head. The first and second loops, he'll be a ball when he moves across. If you're good, you can hit him three times on both of those and on the third loop, you should be able to beat him since he dashes. He dashes to and fro once, then repeats the process. He's eight hits to beat.
