Sonic the Hedgehog 3 Plot Synopsis
Sonic the Hedgehog 3 is the latest film in the Sonic the Hedgehog movie universe. It’s set sometime after the 2024 Knuckles series. In it, Sonic (voiced by Ben Schwartz), Tails (voiced by Colleen O’Shaughnessey), and Knuckles (voiced by Idris Elba) join forces to defeat Shadow the Hedgehog (voiced by Keanu Reeves).
Shadow pulverizes Team Sonic, forcing our team to seek help from Dr. Ivo Robotnik (played by Jim Carrey). With this alliance, will Sonic and his friends defeat Shadow?
How does Sonic The Hedgehog 3 begin?
We begin the film at Prison Island. Two G.U.N. agents monitor Shadow while he is in stasis. With help from “Robotnik,” Shadow breaks free, fights a few G.U.N. agents, and heads to Tokyo. Meanwhile, Sonic and his friends celebrate Sonic’s “B-Earth” Day.
Rockwell (played by Krysten Ritter) and other G.U.N. agents visit Sonic’s group at night. She tells Sonic, Tails, and Knuckles that G.U.N. needs their help with an issue in Tokyo. Sonic, Knuckles, and Tails travel to Tokyo and confront Shadow.
Shadow defeats them and departs. Then, a chase sequence ensues between Shadow and Sonic, resulting in Sonic’s defeat.
What does Commander Walters tell Team Sonic at the Chao Garden? Does Walters die?
Sonic and Commander Walters (played by Tom Butler) discuss Shadow’s origins at a Chao Garden in Tokyo. Walters tells Sonic a meteorite crashed on Earth 50 years ago. He says Shadow was inside the meteorite and a certain scientist (likely Gerald Robotnik) adored Shadow’s “chaos energy.”
However, Walters says an accident occurred at the laboratory Shadow was at, resulting in many deaths. Walters says Project Shadow’s leader was blamed and imprisoned for the incident. Since no one knew what to do with Shadow, Walters had others place Shadow into stasis.
Several Egg Drones arrive at the Chao Garden, including a masked cyclist (Agent Stone in disguise). The cyclist defeats the drones and drives off. Sonic’s group finds Walters underneath some rubble. Walters hands Sonic a key to G.U.N.’s most powerful weapon and dies.
Who is Maria Robotnik? Does Maria die?
Maria Robotnik (played by Alyla Browne) is Gerald’s granddaughter and Ivo’s cousin. She finds and toys with Shadow. Shadow doesn’t like Maria at first. However, Shadow develops a deep connection with Maria through mischievous and heartfelt activities.
While Maria and Shadow gauze at the stars, she reassures Shadow he is her friend. On the day of the accident, Gerald tells Shadow and Maria they must depart from the laboratory. Gerald says G.U.N. wants to take Shadow from them. Several G.U.N. agents chase Shadow, Gerald, and Maria. One of the agents points a gun at them.
A young Walters (played by James Wolk) tries to stop the agent, but the agent shoots a canister. An explosion occurs, killing Maria in the process.
Why does Robotnik team up with Team Sonic? What is the Eclipse Cannon?
Agent Stone (played by Lee Majdoub) tells Ivo Robotnik (played by Jim Carrey) that an imposter is using his technology. Ivo tracks the imposter’s whereabouts. Knuckles and Tails convince Sonic to team up with Ivo. Sonic hands Ivo one of his quills to seal the deal.
Our gang heads to the imposter’s location using Sonic’s rings. The locale is the laboratory where Maria perished. After Knuckles destroys the entrance door, our gang splits into three groups. Shadow takes out everyone besides Ivo.
Ivo meets his grandfather Gerald Robotnik (played by Jim Carrey). Ivo and Gerald greet Team Sonic, Shadow, and Stone. Shadow steals Sonic’s key. Gerald shares intel about a powerful weapon he created called the Eclipse Cannon.
Gerald says he gave G.U.N. the cannon in exchange for his freedom. He tells everyone he wants to use the cannon to destroy G.U.N. HQ. However, Gerald needs the second key to activate his weapon. Shadow activates a black hole-summoning device to kill Sonic and his friends. He, Ivo, Gerald, and Stone depart to G.U.N.’s HQ in London.
What is Tails’s heist plan? Who gets the second key?
After Team Sonic escapes, they head to Tom (played by James Marsden) and Maddie’s (played by Tika Sumpter) home. Tails develops a heist plan. He wants Maddie and Tom to insert a USB drive into one of G.U.N. HQ’s servers.
After that, Tails wants Sonic to navigate through the laser hall and reach the vault. As for Knuckles, he’s tasked with shattering the HQ’s shield in case Sonic can’t enter the base. In London, Maddie and Tom use Tails’s disguise gadget to reach the server room and insert the USB.
Tom spots Ivo’s USB and informs Tails. Tails tells the others that Ivo and Gerald are heading to the vault. Ivo and Gerald reach the vault thanks to their special suits. With his friends’ assistance, Sonic reaches the vault to confront the Robotniks.
Rockwell prevents Sonic, Ivo, and Gerald from getting the key. Knuckles arrives, breaks a device, and chaos ensues. Rockwell loses and retains the key amidst the madness. Tom disguises himself as Walters to convince Rockwell to hand him the key.
Shadow assaults Tom to get the second key, angering Sonic.
What is Gerald Robotnik’s true plan? Does Ivo betray Gerald?
Gerald, Ivo, and Shadow enter the Eclipse Cannon and the Robotniks activate it. They head into space with Shadow. Sonic convinces Knuckles to tell him where the Master Emerald is. He heads to Wade Whippel’s (played by Adam Pally) home. Sonic uses the emerald’s power to become Super Sonic.
Sonic heads to space to confront the Robotniks and Shadow. Shadow powers the Eclipse Cannon. Gerald tells Ivo he wants to destroy Earth with the cannon and die. Ivo wants to rule the world but Gerald doesn’t like his idea.
Gerald argues destroying Earth would give Maria’s life meaning. Sonic arrives, grabs Shadow, and the two fight on Earth. Simultaneously, Ivo betrays and fights Gerald.
How does Sonic convince Shadow to betray Gerald? Does Gerald die?
Eventually, Sonic and Shadow head to the moon. Sonic remembers Tom’s words at the B-Earth Day party and stops fighting Shadow. Shadow and Sonic bond over their losses. Shadow and Sonic team up to stop the cannon.
Meanwhile, Gerald defeats Ivo and learns about Shadow’s betrayal. Gerald sends G.U.N. robots after Shadow and Sonic. Then, Gerald sends Ivo into space and thinks he’s won. Ivo, Knuckles, and Tails appear behind Gerald. Ivo uses Sonic’s quill to hurl Gerald into the cannon’s chaos energy.
Gerald dies.
How do Sonic and his allies stop the Eclipse Cannon? Do Ivo Robotnik and Shadow die?
Shadow and Sonic defeat Gerald’s robots and hold off the cannon’s laser. Ivo, Knuckles, and Tails steer the cannon away from the Earth. Sonic falls unconscious. Knuckles gives Tails one of Sonic’s rings and throws him out of the cannon so he can save Sonic.
Meanwhile, Shadow enters the cannon. Shadow convinces Ivo to stabilize the cannon’s reactor. Shadow promises to steer the cannon elsewhere before it explodes. Ivo hosts a live stream and bids farewell to Stone.
At the same time, Knuckles rescues Tails and Sonic. Knuckles and the others arrive at a plantation field. The cannon explodes. Ivo and Shadow presumably die.
How does Sonic The Hedgehog 3 end?
Sonic wakes up and Tails updates him on Shadow and Ivo’s demise. The former apologizes to Tails and Knuckles for his actions. They accept Sonic’s apology. Stone looks at the sky and bids farewell to Ivo. Some time passes. Sonic, Tails, and Knuckles create meals at the campsite.
Maddie and Tom exit their tent to join them. Sonic, Knuckles, and Tails continue their race. Sonic the Hedgehog 3 ends with Sonic, Knuckles, and Tails leaping into the sunset.
Does Sonic the Hedgehog 3 have a mid-credits and end-credits scene?
Yes. Sonic the Hedgehog 3 has a mid-credits and end-credits scene. The mid-credits scene features Sonic winning the race between himself, Tails, and Knuckles. Sonic finds himself in a forest located near New York State Park. A robot that looks like Sonic arrives on Earth.
This is Metal Sonic, one of Sonic’s enemies from the games. Metal attacks Sonic and Sonic retaliates. Multiple Metal Sonic robots approach Sonic. Before the Metal Sonics attack Sonic, an unknown figure saves Sonic with their hammer.
The unknown figure removes their disguise. She’s a female hedgehog like Sonic. This is Amy Rose, one of Sonic’s female companions from the games.
