Sonic the Hedgehog (Paramount)

History
Sonic was born on an island which carried all the details of the famed Green Hill Zone from the video games, and was raised by the wise Longclaw, who had warned Sonic not to show off his powers as there were those who coveted it and wanted it for themselves. One day, when Sonic returned home to Longclaw with a flower, he and Longclaw were attacked by a group of Echidna warriors who had seen Sonic and followed him back to Longclaw's hut. When Longclaw is wounded by one of their arrows, she realizes Sonic won't be safe with her anymore, and using a ring, summons a portal for Sonic to escape through, giving him the bag of rings to use should he ever need to flee to protect himself from threats, before sending him through and making a heroic last stand to hold the echidna warriors off until the portal dissolves and Sonic is left stranded on the world Longclaw sent him to.

Fast forward ten years since then, and Sonic has edged out a new life for himself on Earth in the woods on the outskirts of Green Hills, Montana, in the United States of America, having filled a cave where he spends most of his time with things he enjoys, such as reading DC comics of The Flash, using a washing machine as a home gym, practicing his martial arts with nun-chunks as his security system, and generally traveling into town, but staying hidden, to spend time watching Green Hills Sheriff Tom Wachowski and his wife Maddie, whom he nicknames "Donut Lord" and "Pretzel Lady" due to the yoga Maddie does and Tom talking to donuts, always thinking of the friends he could have, but remembering Longclaw's warning, has to keep his distance from them to avoid drawing attention to himself. One of his favorite movies he enjoys watching from outside the Wachowskis' home is the 1994 blockbuster Speed starting Keanu Reeves, as Sonic always enjoyed the famous quote from the bad guy, Howard Payne, that being "Pop quiz, hotshot". However, he has drawn the attention of the town's local loony hermit, Crazy Carl, who dubs him "The Blue Devil", and Sonic enjoys having fun with him when he tries to catch Sonic with his various traps and fails.

One night, after watching a baseball game earlier that evening, Sonic tries to play by himself, but when he looks at the empty bleachers, he becomes so upset that he begins running around the bases, faster and faster, his sadness changing to anger and frustration, until he builds up so much energy that it soon is unleashed in a powerful electromagnetic pulse (EMP) that blacks out the Pacific Northwest in the process.

This, unfortunately, attracts the attention of the United States Department of Defense when word reaches their headquarters at the Pentagon in Arlington, and Commander Walters, Vice Chairman of the Joint Chiefs of Staff, suggests calling on Doctor Robotnik to aid in finding the source of the EMP, despite concerns from the other Joint Chiefs about Robotnik's M.O. from previous encounters with him.

When Sonic hears Robotnik's robots and the United States Army soldiers searching the woods for him, terrified of them finding him, and unable to escape from his cave to the next world he intended to head for if Earth was no longer safe for him when he hears the search dogs above, he flees to the Wachowskis' house to hide in their shed, but the commotion he makes inside alerts Tom, who comes in looking for raccoons, and finds Sonic, just as he was preparing to leave for the next world, and in fear, shoots Sonic with a tranquilizer. As Sonic begins to pass out from the sedative, he momentarily thinks of San Francisco from Tom's T-shirt, and opens a portal to the Transamerica Pyramid instead, dropping his ring bag through it before passing out completely. When he comes to, it is not long before he and Tom get into an argument, but when Robotnik arrives at the house, Tom hides Sonic in the attic while he deals with Robotnik. However, Sonic ends up downstairs to evade Robotnik's drones searching for him, and when Robotnik finds one of Sonic's quills and threatens to kill Tom if he doesn't tell him the truth in five seconds, in desperation, Sonic reveals himself, freaking out Robotnik long enough for Tom to cold-cock him before they fight off Robotnik's now hostile drone and flee in Tom's Toyota pickup.

At one point, Tom stops to let Sonic off to head for San Francisco on his own, but Tom's general suggestion of heading west leads to Sonic ending up in the Pacific Ocean before coming back and asking for Tom's help to get to San Francisco. With little other choice, Tom agrees to help Sonic, and they make their way to the City by the Bay, unaware of Robotnik now hunting for them, declaring Sonic an alien and Tom a domestic terrorist for protecting Sonic from Robotnik and the U.S. military.

Stopping at a biker bar, Sonic soon learns about creating a bucket list of things to do before you die, or in Sonic's case, leave Earth for another world, and after causing a bar brawl that Sonic easily handles in supersonic speed mode, he and Tom flee to stop at a motel for the night, where Tom begins to show some affection and friendship with Sonic when he tucks him in for the night.

The next day, they soon find that Robotnik has caught up to them when he sends a large tank drone after them on the highway, and despite Sonic and Tom's best efforts, the drone proves persistent in stopping them, culminating in a small, helicopter drone that emerges from the wreckage of the larger ones slicing off the roof of the cab of Tom's pickup before Sonic breaks it in half, only for its core to become a powerful sticky bomb that leaves Sonic severely wounded and unconscious when it detonates. Terrified for Sonic's well-being, Tom takes him to Maddie, who was visiting her sister and niece at that time in San Francisco, who manages to revive him. While there, Sonic is granted a gift from Tom and Maddie's niece Jojo in the form of new shoes to replace his worn-out ones. With the new shoes, and Maddie joining Tom in helping Sonic out, they travel to the Transamerica Pyramid, where Tom is able to gain access to the roof due to his position as a law enforcement officer, and Sonic recovers his ring bag.

However, before he can leave for the next world and leave Tom, Maddie, and Earth behind, he is confronted once more by Robotnik, now flying the Prototype with an army of his drones with him. Sonic, in order to save Tom and Maddie's lives, pushes them off the building before using his supersonic speed to take out Robotnik's drones and also save them, but using the quill he captured earlier back at Tom's house, Robotnik is able to enter supersonic speed himself and nearly ruin Sonic's rescue attempt. Sonic manages to get Tom and Maddie, transported by ring portal, safely back to Green Hills, before dealing with Robotnik and the Prototype, having their chase pass through Paris, the Great Wall of China, and the Great Pyramids of Egypt, before Sonic attempts to escape back to Green Hills, but Robotnik manages to land a powerful hit just as Sonic is about to enter the portal, causing Sonic to be mortally wounded and left at Robotnik's mercy as they return to Green Hills.

Robotnik prepares to take Sonic back to be dissected to learn the secrets of his powers. Tom then tries to protect Sonic by attacking Robotnik himself, but is quickly overpowered. However, the people of Green Hills rally to Tom's aid, angry at Robotnik for attacking their Sheriff and Sonic, and when Tom declares Sonic his friend, Sonic gains a miraculous second wind, and soon begins to glow with that same power that gave away his location previously, but now in full control of it, intending not to run, but to protect his friends, and unleashes his fury on the Prototype, severely damaging it before Tom and Sonic open a portal to the mushroom world Sonic intended to travel to previously, but deciding Earth is his home now, with a final, powerful spin attack, Sonic destroys the Prototype and sends it and Robotnik through the portal, never to threaten anyone again.

Some time later, Tom and Maddie reveal to Sonic that they transferred all his stuff from his cave to their attic, making it up so Sonic can use it as his room and live with them from now on, much to his joy. Commander Walters soon stops by himself to reveal to Tom and Maddie that any and all information about recent events regarding Sonic and Robotnik have been erased by authority of the U.S. government, and to keep Tom and Maddie quiet about it, offers them an Olive Garden gift card as thanks. Sonic soon settles into his new life living in Green Hills with Tom and Maddie, now among friends at last, proving that his earlier fears and warning from Longclaw were no longer needed.
