Sonic RPG episode 8

The story begins as Sonic takes a vacation on the beach. Dr. Eggman comes and sends out a clone of Chaos, the water monster, attacks him and is about to defeat him, when Shadow arrives on the scene to stop Eggman. He used Chaos Control to defeat Chaos, but Eggman takes that chance while the two of them were fighting to copy their battle data and steal Shadow's Emerald. Sonic commands Shadow to find Knuckles at Mystic Ruins and get the Master Emerald. After a battle in which Shadow was almost defeated, Knuckles decides to trust him and went with him.

Meanwhile on the Death Egg, Sonic arrives and confronts Eggman. After explaining to a stunned Eggman about how he can use Super Sonic form now and fly, Eggman battles him with a Greater Digegr Robot. After Battle, the onboard computer states on the PA that the "creation" and "experiment" has been finished. With the dream of Egg Empire drawing closer with the new creation, Eggman immediately activated it and named it "Sonaw". The mysterious dark entity pummels Sonic and asks Sonic where was Shadow. Shadow arrives together with Knux and confronts "Sonaw". While Eggman was naming it Sonaw, the dark hedgehog suddenly interrupts, stating that it was created for the purpose of destroying Sonic and Shadow, it now wants to enslave everybody and names itself Seelkadoom. Eggman realizes that the creation was uncontrollable and decides to send all the people on board to an alternate dimension via a portal.

While being transported, Sonic questions himself about whether he would die. After being woken up from his slumber by a purple figure, he asks who is he. The purple entity introduces himself as Nights, and says that his friends told him his name already. Sonic asks Nights where were the others? Nights says that they had left, Shadow to the Dark Castle and Knux to find out how to escape this dimension. He then explains what happen to his since Seelkadoom got here. Ever since his arrival, NiGHTS' brother, Reala, joined forces with him. They defeated Knuckles, Shadow, and himself. He then tells Sonic that they should hurry to the Herbegitan Temple so they can get the Sapphire. Sonic runs ahead of NiGHTS, who follows him.

Once they got inside of the temple, they found the Sapphire... and the Guardian of the Sapphire, Ristar. After battle, Ristar understood what Nights and Sonic were trying to do, but before he could give the Sapphire to them, he got attacked(and unconscious or killed) by Reala, who took the Sapphire himself. Seeing this, Sonic became Super and went after him, with Nights, following him. Reala lost the Sapphire to them, but while he was flying away with Super Sonic, they engage into battle. Despite being in Super form, Sonic was no match for Reala. When Sonic woke up, he sees that Reala was gone, but he was reunited by Knuckles and NiGHTS. After being healed by Nights, he and himself went to the Reala's Castle to save Shadow while Knuckles tries to find a way back to Mobius.

They finally got to the Dark Castle, with Reala waiting for them. Nights told Sonic to find and fight Seelkadoom and he'll deal with his brother. Sonic begrudgingly agrees, flying away from the battle between Nights and Reala. Sonic found Seelkadoom and prepared to fight him. Shadow joined in after being defeated by Seelkadoom. The two hedgehogs fought against Seelkadoom, but Seelkadoom was able to defeat the two of them with his ultimate attack. However, after his attack, Seelkadoom was weak, and Sonic and Shadow were revived, due to Nights giving them the energy from the Holy Sapphire. Shadow suggested to finish Seelkadoom off for good, but Sonic disagrees and gets Shadow out of the battle.
