South Island Arc

The **South Island Arc** is the first arc of the **Sonic Chronicles** series. It introduces the main protagonist, **Sonic the Hedgehog**, and his soon-to-be arch-nemesis, **Dr. Robotnik**, and his nephew, **Snively**.

## Plot

The story begins on **South Island**, known for being a treasure trove of ruins and gems. Amongst these treasures are the **Chaos Emeralds**, six legendary gemstones with enough power to bring energy to all living beings, or power nuclear and laser weapons through science and technology. However, nobody really knows how to obtain these gems. This is because South Island is a moving island, with the Emeralds existing within natural distortions on the island.

One day, danger comes upon South Island when the infamous Dr. Ivo Robotnik, a human mad scientist, lands on it with his henchman, Snively, and his many **Badnik** minions. Soon after his arrival, he builds the **Scrap Brain**, a huge fortress on one corner of the island where he develops his plans. He also begins hunting the Chaos Emeralds in order to use their incredible power, declaring that he will find them even if he has to dig up the entire island.

Sonic the Hedgehog, a speedy blue hedgehog who lives on the island, learns of Dr. Robotnik's ambitions through the Mobinis on the island and rushes to **Green Hill** to stop the doctor. He soon after finds the villain, who gloats that he has caught all the local Animals and turned them into his mindless Badnik servants. Unfazed by this taunt, the hedgehog travels through the various **Zones** on South Island, freeing the **Mobinis** and defeating Robotnik and his various contraptions along the way while hunting for the Chaos Emeralds.
Eventually, Sonic infiltrates the Scrap Brain. After being cornered inside, Dr. Robotnik activates a trap that destroys the floor the hedgehog is standing on, dropping him into the ruins underneath the base. Making his way back into the stronghold, Sonic enters a **trap-ridden room** with his nemesis in it. When the hero destroys the room, a defenseless Robotnik tries to escape in his **Egg Mobile**. Before the forces of evil can escape, however, Sonic lands a final hit on the hovercraft, defeating the mad scientist and causing him to slowly fall down.

With Robotnik's ambitions (and the Scrap Brain) crumbled, peace has returned to South Island, all Badniks have been destroyed, the Mobinis are liberated from their **Capsules**, and the island's treasures and jewels are safe once again. Sonic then returns to Green Hill with all six Chaos Emeralds, where he finds the local Mobinis joyfully jumping around and celebrating his victory. Using their power, Sonic fills the entire Zone with large, colorful flowers. After being shocked by this for a split second, Sonic then witnesses the Chaos Emeralds scatter and vanish, assumingly back into the **Special Zone**.
