Angel Island Zone (エンジェルアイランドゾーン Enjerutōirandozōn?) is the fifth Zone in Sonic Advance. As its name implies, the Zone is set on the skies of Angel Island. Like other Zones in the game, Angel Island Zone consists of two Acts, with a boss at the end of the second.
Angel Island Zone is set in ancient ruins high above the island's landmass, giving it a closer resemblance to Sky Sanctuary Zone and a slight resemblance to Marble Garden Zone than the forest-like Zone it shares its name with.
Dr. Eggman visited Angel Island Zone during his quest to establish the Eggman Empire by finding the Chaos Emeralds and turning Animals into Badniks. Hot on his heels however, were Sonic, Tails, Knuckles and Amy, who came to Angel Island Zone, where they freed the Animals and found a Chaos Emerald there. Later, Eggman's newest creation, Mecha Knuckles, battled them, but was defeated. With Eggman fleeing from Angel Island Zone, Sonic and co. followed him.
Alongside a number of booby traps, such as moving platforms, floating spikeballs, and sand falls, the Zone also contains many old contraptions that can help the player. These include such as rolling balls that the player must run on the make them move, as well as overhead rails and hanging handles that elevate the player when used. Failing to use some of these contraptions will dump the player into bottomless pits, which appear often during the level.
Angel Island Zone also contains many shout outs to the original Angel Island Zone and other Zones that appeared in Sonic the Hedgehog 3 & Knuckles. The Rhinotank and Wamu enemies are very similar to the RhinoBot and Catakiller, Jr. enemies respectively. The bouncing clouds are similar to the ones found in Sky Sanctuary Zone.
At the end of the Act, the player gets trapped inside an arena where they must do battle with Mecha Knuckles. After defeating the robot, Dr. Eggman will appear and flee, dropping a capsule with Animals trapped inside in the process. Open the capsule to complete the Act.
The boss of Angel Island Zone is Mecha Knuckles. The fight starts out with the boss using Spin Dashes, Glides, and punches to harm the playable character. However, after Mecha Knuckles gets hit enough times, its outer shell will break off, revealing a more sinister-looking metallic endoskeleton underneath. In this form, its speed is greatly increased, and gains a new attack in which it launches a barrage of giant homing missiles from its mouth. Hit it a total of eight times on Normal mode, or six on Easy mode, to defeat it.
