Bedlam

Bedlam is a character and overarching antagonist in Sonic Stop Motion Adventures, where he only appears in the second half of the final season as the main antagonist. He is a red hedgehog who has the role of "Moderator of the Chaos Emeralds." Bedlam was released into the real world when Tails' machine tries to make the Emeralds work into their natural state. His goal and mission was to destroy Sonic and Dr. Eggman for overusing the Chaos Emeralds. He is later reformed after Sonic defeats him and losts his title as the Moderator to him.

Origins
Not known about Bedlam's backstory before becoming Moderator, but Bedlam must've fought Moderaters before him in the Moderator Dimension and resides it after losing their title to them. During the events of the seasons 2-3, Bedlam watches Sonic and his friends every moment they were using the Chaos Emeralds.

Role in the series
He first appears in the end of "Chaos Buffer" after the Tails activate his machine to fix the Chaos Emeralds which causes an earthquake.

In "Call me Bedlam", When Tails, Knuckles, Shadow, Amy and Silver asked why he is here, Bedlam tells him that his goal is to take the Chaos Emeralds and his main part of it is kill Sonic and Dr. Eggman for using the Chaos Emeralds too much. Shocked and outraged, Knuckles, Shadow and Silver gets into a fight with Bedlam. When Shadow absorbs the Emeralds, which appears to working more than five seconds, after Bedlam told him, he decides to put him on his kill list. After Bedlam uses Chaos Control Spear on Shadow, he prepares to take down him down, but was stopped by Sonic, who reveals that he actually watches the fight before joining in. Sonic recgonizes the symbol he saw his nightmare in Bedlam right eye. Sonic tries to defeat Bedlam, but Bedlam performs Chaos Control and brutally knocks him unconscious. Before Bedlam tries to completely destroy Sonic, Shadow stops him by using Chaos Control Spear, so Tails can escape with Sonic in his Tornado. After that, Bedlam knocks the Chaos Emeralds out of Shadow and takes them, and decides to give Sonic and the gang one week until he returns. Afterwards, he visits Eggman in prison to explain that he could kill him after taking down Sonic and Shadow first.

In "Shot in the Dark", as one week has passed, Bedlam is ready to fight Sonic. Bedlam has a meeting with Sonic, Knuckles, Shadow and Silver at the abandoned, ruined building where it is a place battle. As they are fighting, Bedlam feels disappointment in them after giving one week. Bedlam was about to finish Sonic off, but is stopped by Metal Sonic, whom Eggman reprogrammed to be sided with Sonic and his friends to fight Bedlam. Shadow, feeling overshadowed by Metal Sonic, steps up and removed his Inhibitor Rings to be overpowered enough to take down Bedlam, but getting exhausted from it. Sonic comes out in his super form because of Tails' E.E.M. which turns out to absorb the power of the Chaos Emeralds while trying to fix the Chaos Emeralds. Surprised and enraged, Bedlam decides to use the Chaos Emeralds to go super as well, turning into Frantic Bedlam. When the two enemies perform Chaos Control at the same time, they seem to be transported to a world between dimensions, where all Moderators like him have been resided.

In the series finale, "Forward," while Sonic and Bedlam fight, Sonic points out to why he used the Chaos Emeralds for various reasons (like trying to stop Eggman.) However, Bedlam still being careless about everything Sonic told him, telling that using the Chaos Emeralds too much is the same thing, but Sonic talks senses on him that he shouldn't use the Chaos Emeralds, too, when he told anyone not to use them. This enraged Bedlam and prepares to get Sonic out of the picture for good. Bedlam finally sends Sonic into his critical state, giving him his death wish. However, after Tails', Knuckles, Amy, Shadow and Silver convince him not to give up, Sonic decided step up to continue to fight Bedlam. After knocking the Chaos Emeralds out of him, Sonic absorb the Chaos Emeralds while in his super form, this turning into Hyper Sonic. After defeating Bedlam, Sonic discovers that the symbol is placed in his left hand, meaning he is the new Moderator of the Chaos Emeralds. Bedlam apologizes for his actions, and suggests that Sonic should stay in the Moderator Dimension because of this place is made for all Moderators before the him and Sonic. However, Sonic tells him that he already have a life back in the real world. Bedlam decided to stay here instead, performig Chaos Control for Sonic to transport back into the real world.

Personality
As the Moderator, Bedlam is naturally arrogant, typically looking down on those he sees as less than him. Despite this he often speaks in a well-mannered tone, only when the Chaos Emeralds gets corrupted, he becomes threatening, violent and overly aggressive. Due to this, he shows no qualms of killing anyone who uses the Chaos Emeralds frequently, thus taking his job very seriously.

Despite that, while off duty, he is shown to be more than capable at befriending people such as Big the Cat and Froggy. All in all, he only does what he deems best for the sake of the world and the Chaos Emeralds.
