Angel Island

Angel Island is an island that floats through the skies of Mobius, suspended by the mystical powers of the Master Emerald. The power of the magical gemstone has made the island a target for villains such as Dr. Eggman; fortunately, it is protected by its Guardian Knuckles, the last known survivor of the Echidna race.

Angel Island (originally/also known as the Floating Island) is a large landmass which floats high above the planet Mobius' surface. Originally a part of the continent of Downunda, the Echidnas living in the city of Echidnaopolis decided to use the powers of 12 Chaos Emeralds to lift their city off the surface to avoid destruction by a White Comet. Since then, Angel Island has been the home of many different species, the two largest being the Echidnas and the Dingoes. After the Dr. Eggman-backed Dingo Regime's mass genocide under Kage Von Stryker, the Echidna population was left in shambles. Those who survived were relocated to Albion by Enerjak, to ensure the survival of their species, while the Dingos themselves were disarmed and exiled to Sandopolis Zone. It is largely uninhabited except for the Dingoes, agents of the Knothole Freedom Fighters, Chaotix and the island's last Guardian; Knuckles.


Ancient History

Angel Island came into being roughly 4,000 years ago, when the ancient Knuckles Tribe, an Echidna clan led by Pachamac, learned of a powerful gem, the Master Emerald, which rested at a shrine on the outskirts of their settlement, and planned to seize it in an attempt to obtain ultimate power. When this time came, Pachamacs daughter, Tikal, stood between them, and begged her people to leave the Emerald and peaceful colony of Chao that resided there. When the clan continued onward regardless, this angered the emeralds guardian, the water beast Chaos, who appeared and wiped out the echidnas. Tikal prayed to the emerald to calm Chaos down when it's rage became uncontrollable. The gem absorbed both of them into itself in the process continuing to surge energy into a large part of the continent, causing it to break away from the rest and float into the sky with the remaining echidnas, creating Angel Island. The surrounding settlement was left behind to become what would ne day be known as the Mystic Ruins.

Much of Angel Island is populated by ancient ruins, either built before or after the island was lifted into the sky. The function and purpose of many of these was eventually forgotten, but they included numerous traps and other technology that functioned into the present day. In particular, a number of control hubs for the traps dotted the island, while other ancient computers existed in such places as the Launch Base Zone. (SU: #63, #70, VG: SA/SADX)

Repairing the Death Egg

After his defeat at the hands of Sonic and Tails, Dr. Eggman's Death Egg crash landed on Angel Island, resulting in the floating island sinking down to the water's surface. Dr. Eggman used the Launch Base Zone as his base for repairs and apparently messed with the systems. He eventually repaired his flying fortress and took off into the sky with Sonic and Tails pursuing him, resulting in another crash landing on Angel Island's Lava Reef Zone. Dr. Eggman eventually obtained the Master Emerald from the Hidden Palace Zone during a battle between Sonic and Knuckles, who he tricked into thinking Sonic and Tails were thieves, and used it as an energy source to fuel his Death Egg. His repaired flying fortress one again took off into the sky with Sonic, Tails, and Knuckles in pursuit. Eventually, the Master Emerald was recovered, and the island once again rose into the sky. (VG: SH3aK, SU: #64)

Dr. Eggman later had his assistant, Dr. Julian Snively, capture the Master Emerald for him, in which he did so with an EggRobo. Knuckles raced after the thief all over the island, and, after multiple encounters, successfully recovered the Master Emerald once again. (VG: S3aK, SU: #70)

Master Emerald Shard Hunting

Sonic Adventure History

Chaos is released from the shattered Master Emerald.

When Dr. Eggman shattered the Master Emerald in order to release Chaos, an ancient water elemental long imprisoned inside the stone, Angel Island once again fell to the planet's surface near Mystic Ruins. With the fragments scattered across the world, Knuckles was forced to leave the island in order to recover them. Meanwhile, archaeologist Relic the Pika came to the fallen island to investigate. Working together with Sonic, Tails, Amy Rose, and others, Knuckles succeeded in restoring the Master Emerald, Chaos was pacified and returned to its home inside the Master Emerald, and the island once again lifted into the sky. (VG: SA/SADX, SU: #69)

Sometime after these events, Knuckles made the acquaintance of Relic, who convinced Knuckles to let her stay on the island. The next female visitor to the island was nowhere near as friendly: the thief Rouge the Bat attempted to steal the Master Emerald, only to be beaten to the punch by Dr. Eggman. In order to prevent the mad doctor from using the Emerald's power for his latest scheme, Knuckles shattered the Emerald himself, causing the island to fall to the planet's surface once again. He then proceeded to search the planet for the shards yet again, but he eventually managed to recover all the Emerald shards, and participated in Eggman's defeat yet again before returning home. In the end, Angel Island rose to the sky once again. (VG: SA2/SA2B, SU: #63, #69)

Rocked by Shattered Continents

Angel Island Tipping

Angel Island as the planet below shatters.

When The Shattered World Crisis hit the world, Angel Island was affected by the upheaval as well, though not as drastically as the surface. Most notably, Chaos emerged from the Master Emerald and dropped to the planet's surface, while Tikal spoke to Knuckles regarding the crisis. Learning that the spirit known as Light Gaia had the power to restore the planet but was in need of help, Knuckles set out to find him. In leaving, he put archaeologist Relic the Pika and her robot assistant Fixit in charge of the Master Emerald. (SU: #63)

Relic and Fixit soon ran into problems, as they detected strange activity elsewhere on the island. Upon investigating, they came across a strange root, which they took a sample of in hopes that it could be examined back at the Flying Battery Zone. Unbeknownst to them, however, the root was a sign of the presence of Eclipse the Darkling, last surviving member of the Black Arms. Upon determining that the island was under threat, they alerted the returning Knuckles, and were soon joined by further unexpected visitors: the members of Team Dark. An uneasy alliance between Knuckles and the G.U.N. agents broke down when Shadow the Hedgehog insisted upon moving the Master Emerald to a more secure location, but they managed to put aside their differences when Eclipse and his Dark Arms seized the gem. Knuckles and Shadow managed to intercept Eclipse after he fought his way through many of the island's traps, and Knuckles shattered the Master Emerald once again to keep it out of the hands of both sides. Fortunately, the planet's shattered state allowed Angel Island to remain aloft, but Knuckles set out almost immediately to recover the Emerald's shards, knowing that the island would plummet yet again were the planet restored before the Master Emerald.

Echidnaopolis flying into the air.

Hundreds of years ago a group of Echidnas known as the Knuckles Clan, having set out from their homeland of Albion, eventually settled in a region of Downunda and built the city of Echidnaopolis. (KtE: #12)

The technologically-advanced city thrived on the mainland until roughly 600 years ago when the two scientists Jordann and Kayla-La discovered the White Comet that would soon impact directly on the city. Desperate to save their home, Kayla-La developed and proposed a plan to physically move the city out of harm's way using the power of Chaos Emeralds. After excavating twelve of the rare and powerful gems, the Chaos Chamber was established to harness the energy of the emeralds. After the Fire Ants dug under the foundations of the city, separating it from the planet's surface, Echidnaopolis lifted into the sky, becoming the Floating Island. A large crater marks its former place in Downunda. (StH: #34, #82, KtE: #10)

Dimitri and Edmund's Plan

Four generations later, the great-great grandsons of Jordann and Kayla-La, Edmund and Dimitri, sought to return the city to its original site on the planet. While the energies of the Chaos Emeralds weren't completely understood, Edmund and Dimitri theorized that, should the energy be gradually drained, the decent of the island could be controlled and allow it to slowly, safely return to the mainland. The two developed a device called the Chaos Syphon, capable of draining away Chaos energy, and proposed their plan to the gathered council. However, due to the current High Councilor's personal political goals, as well as resentment from the Theocracy within the High Council towards the Technocracy for having saved Echidnaopolis in the past, the plan was rejected, officially on the grounds of being too dangerous a move. (StH: #35, KtE: #1, #23, #24)



A Dark Legion attack.

See also: Dark Legion

After Dimitri's presumed death when his Dark Tower collapsed on him, and the High Council's decision to ban excessive technology, those opposed to this and loyal to Dimitri formed the Dark Legion. The Legion was transported to the Twilight Zone by the Guardian Steppenwolf, as they initiated a civil war with the remaining Echidnas. After this, the Dark Legion had occasionally managed to break through the dimensional barriers and attempt to retake Echidnaopolis, though each time they were repelled by the current Guardian. (KtE: #16, #17, #18, #25)

Angel Island's two primary species were the Dingoes and the Echidnas. The Dingoes, an aggressive militant race, attempted numerous times to wipe out their echidna counterparts. After stealing a cache of nuclear weapons, the Dingoes attempted a nuclear strike on Echidnaopolis. The city was saved by an energy dome erected by the current Guardian of the time, Hawking; however, the fallout spread across the island. Both Echidnaopolis and the Dingo cities, as well as other civilizations on the island, were then transported to their own zones where they were protected from the harmful radioactive fallout until Hawking and several future Guardians could restore the island to health. Echidnaopolis was returned to the Prime Zone when the dimensional barriers were weakened by Dr. Ivo Robotnik's firing of the Ultimate Annihilator. The Dingoes were also returned to the Prime Zone, their city however remained in its own zone. (SSSM: #2, StH: #50, KtE: #5)

Dingo Takeover


Eggman takes over Angel Island

Almost two years after the Echidnas and Dingoes had been returned to Angel Island from their Pocket Zones, the dissatisfied Dingoes under the new leadership of Kage Von Stryker turned to Dr. Eggman for support. In exchange for becoming Eggman's enforcers and servants to the Eggman Empire, the Dingoes received technology, supplies and assistance from the Eggman Empire to enslave the Echidna population and completely take over the island. With Sonic the Hedgehog believed dead and far off in space, and Knuckles the Echidna on the surface of Mobius, the overwhelming Dingo forces successfully took control of Angel Island. (StH: #125, #136, #138, #139)

Enerjak's Cleansing

After nearly two years of Dingo oppression, their regime and Dr. Eggman's hold on Angel Island would come to an abrupt end. Knuckles, under the influence of Dr. Finitevus, became the Chaos demigod Enerjak and used his near-omnipotent powers to rid the Dingoes of their technology and banish them to the desert of Sandopolis Zone. The Echidnas who were still alive were then transported to the ruins of Albion where they would be hidden and safe from future harm. When Sonic and Enerjak fought, Shrine Isle was created. A bridge was later added to it. (StH: #181, #184, #186)


Dr. Finitevus eventually came into contact with the Dark Egg Legion in Downunda and made an alliance with them by handing over his Warp Ring technology, allowing them to anchor Angel Island to Downunda and be under the Eggman Empire's control. In return, Finitevus would be allowed back on to the island at any time to study the Master Emerald. His plans were thwarted, however, by the combined efforts of the Chaotix and Downunda Freedom Fighters. (SU: #8, #11, #12)
