Sonic the Hedgehog is an alternate version of the Sonic the Hedgehog from the Sonic X Zone. He was transported from his world to the human world using Chaos Control. Later on, he met a human named Chris Thorndyke.
Sonic's early adventures began as he raced Sam Speed and won. A day later, he fended off Ben-728 Packratbot from robbing a back. A week later, the President gave Sonic a mission: to go to Captain's Seamus "Red-Eye" Macgriffen's ship to retrieve a energy signal that may be a Chaos Emerald. Later that mission, Sonic, Topaz, and Rouge were attacked by a shark then by Dr. Eggman's Dragonbots. Luckily with a little help of Knuckles (and with help of Captain Red-Eye himself) defeated the dragonbots but found no Chaos Emerald. Another week later, Sonic went on to rescue Cream's chao friend Cheese. During that, Bokkun delivered items to Sam Speed, the president, Topaz, and Chris' teacher Mr. Stewart. After rescuing Cheese, Chris went on a field trip to Station Square Space Museum (which was set up by Dr. Oeuf-Homme A.K.A. Dr. Eggman). When there (with Sonic, Tails, and Amy and Chris's class) were ambushed by Eggman's robots. The same time sonic was rescuing Chris friend's Daniel and Francine, Eggaman pushed a button which activated Sam, Topaz, the President, Mr. Stuart, and Chris to trapped in robots. After Sonic rescued the two kids, he came face to face with a robot that had Chris inside. The robot was about to launched missiles at Sonic, but he managed to aim it somewhere else: Angel Island. Once the missiles hit Angel Island, Knuckles went down to help. When Chris managed to break free, Cheese helped the president escape. Once then, Sonic and the gang helped everyone else break free, Eggman made a hefty escape, and the day was saved again. (SX: #1, #2, #3, #4)
After Sonic saved a spotted owl from a forest fire, Eggman began selling clones of Cheese. There was only one thing they did: once Eggman sent a signal to the chaos, there transformed into devil chaos and started to destroy the town.During the battle, Knuckles, Tikal, Chaos, and a army of chaos.Then Eggman showed up with a giant robot (which was quickly defeated by Chaos' good version of Perfect Chaos), after that Sonic began turning all of Eggman's chaos normal with a counter signal. Once after that, Tikal, an Chaos took all the chaos (except Cheese) to the Master Emerald. (SX: #5, #6)
Wanting to spite Rouge and Topaz, Captain Westwood (G.U.N. captain) is given an assignment of a device buried in the desert and plans to bring Sonic to help him make him the top agent again. As Sonic is planning on Chris' birthday party, Captain Westwood pays him a visit and forces him to help him with an operation by lying that the President ordered him to come. Sonic goes after being persuaded by Chris and manages to uncover a robot. Impressed by their discovery, Captain Westwood tries to persuade Sonic to join him, but the robot activates and attacks the two. Sonic uses a shovel and manages to destroy its circuits. Captain Westwood then asks him to join G.U.N. because of his idea to bring him along. Realising that he has been betrayed, he leaves back to the Thorndyke Manor to prepare for the party. (SX: #7)
Trouble in Paris
After Chris' birthday party in Paris, Nelson Thorndyke was going to show his company's creation: a space shuttle. During the invention's preview, Dr.Eggman, Decoe, Bocoe, and Bokkuun were planning to steal the shuttle, with Topaz and Rouge were making sure that Eggman wasn't in Paris. Once the space shuttle was shown, giant robots were attacking the crowd. Eggman flees into a house of mirrors, with Sonic cornering him not noticing Emerl about to destroy him. Another robot stomps through the roof and Sonic defeats the robots. After the battle one robot survived but was damaged (even though no one touched except the other robot). But everyone was distracted, Eggman went off with the shuttle. (SX: #8, #9)
Eggman's Virtual Scheme
After Vector, Espio, and Charmy left mysteriously to their world, Sonic found himself in Green Hill Zone (which was created by Eggman). Sonic began rescuing his friends one by one, while Chris and Chuck Thorndyke were looking for their missing friends. Once they reached the final level, Eggman began the countdown for his old base (which Sonic and the gang were trapped in) to the moon (also with the rocket that he stole). Once Chris and Chuck rescued Sonic then rescued everybody before they were sent to the moon. (SX: #10, #11)
Thrown in Prison
After Dr. Eggman was thrown in prison, Sonic began hanging out with the speed team while Tails and Captain Westwood began fixing and controlling a space pod. But the pod was out of control and attacking the city. Once they figured out who was in the pod, Sonic and Tails were taken in to custody. Captain Westwood had framed Sonic and Tails of working with Eggman and attacking Station Square. After that Sonic and Tails were taken to prison and shared a cell with Dr. Eggman. Chuck Thorndyke called his son and he asked the President if he could drop the charges against Sonic and Tails. After this Sonic and Tails went to a private island were Chris and Cream were having trouble and needed help in order to help their mothers'. Once Sonic put a strange talisman on the sun side and put by a castle (were they first found it) and the ghost returned to their resting place. (SX: #12, #13, #14)

Eggman dressed up like Santa Claus and told the world that he wanted Sonic for Christmas or no gifts. Luckily, Chuck Thorndyke cleared Sonic's named and exposed Eggman's plot. During Valentines Day, after losing a bet to Knuckles, Sonic was forced to take Amy on a date. Though Sonic didn't know what to do so he to the Chaotix Detective Agency (who had mysteriously arrived back to Earth) and asked what to do on the date. During the date, Eggman, Decoe, Bocoe, and Bokkun tried to ruin the date but failed. During St. Patrick's Day, Eggman began looking for the two leprechauns that he saw (which were just a green Cheese and Bokkun). Before Eggman could destroy Sonic, Chris pointed out that leprechauns live at the end of the rainbow and saved Sonic's life. (SX: #15, #16, #17)

Like much of the other versions of Sonic the Hedgehog, he has super speed. He also can take in a energy ring to make him faster and more powerful. Also when in contact with the seven Chaos Emeralds is able to activate his super from.
Sonic's personality in this universe is quite similar to his Prime Counterpart's. The main difference is that this Sonic is shown to enjoy being solitary and is more hyperactive then his Prime Counterpart. He is also shown to have slightly more control of his temper then his Prime Counterpart's.
- Sonic in this universe is biologically a year younger then his Prime Counterpart was at the time of the crossover.
