Angel Island (Classic Sonic's world)

Angel Island (エンジェルアイランド) is a location that appears in Sonic the Hedgehog series. it is an another version of Angel Island from an alternate dimension set in the recent past. Like its counterpart, it is a island held aloft in the sky by the Master Emerald, and the home of Knuckles the Echidna.

Past
Angel Island's early history was most likely largely the same as its mainstream counterpart's. The point of divergence occurred at an early point in Angel Island's recent history, when a Dr. Eggman from another dimension appeared in Angel Island's world during his trip through time in the Time Eater to change history.

Sonic Mania
In Sonic Mania, some time after Angel Island was saved by Sonic and Tails, the island fell to the surface of the ocean once again due to the effects of the Phantom Ruby when it appeared on the island.

Detecting the Ruby, Sonic and Tails soon arrived on Angel Island. There, they met five Egg-Robos who were excavating the island in search of the Phantom Ruby. Upon finding it, the Eggrobos used it to send Sonic, Tails and eventually Knuckles to Green Hill Zone.

After escaping Little Planet, Sonic, Tails and Knuckles literally dropped into Hydrocity Zone during their mission to get the Phantom Ruby away from Dr. Eggman. Midway through the Zone, the team got back at Eggman with his own Egg Mobile when he tried to escape them. Sonic and co. also managed to escape Eggman's final trap at the end of the Zone, although the egg-shaped scientist again eluded capture.

Some time after that, Sonic, Tails and Knuckles arrived in Lava Reef Zone. Midway through the Zone, after taking care of the Drillerdroid, the trio used a Transport to descend deeper into Lava Reef Zone. Arriving at the bottom of the Transport's shaft, Sonic and co. found themselves on Hidden Palace Zone's grounds. Along the way, the crew got split up. Sonic and Tails themselves arrived in the arms of the Heavy Rider and Jimmy, but the heroes were able to defeat them. Meanwhile, Knuckles arrives at the Master Emerald's local altar, just as the Heavy King tried to steal the massive gem. Recalling how Eggman tried to steal the Master Emerald once before, Knuckles stopped the theft and managed to make the Heavy King retreat, despite the robot empowering himself with the Master Emerald. Knuckles then used a Warp Point to catch up to his friends.
