Sonic the Hedgehog 3

In 1974, a meteorite containing Shadow crash-lands in Oklahoma and is seized by the U.S. military. Shadow's power is experimented on by Professor Gerald Robotnik at a Guardian Units of Nations (G.U.N.) research facility under the supervision of Captain Walters; Shadow also develops a close friendship with Maria, Gerald's granddaughter. One night, as Gerald, Maria, and Shadow try to escape the facility to prevent Shadow from being taken away, Maria is accidentally killed in an explosion. Walters shuts down the facility, imprisons Gerald, and places Shadow in suspended animation. In 2024, Sonic celebrates the anniversary of his arrival on Earth with Tails, Knuckles, and their adoptive parents Tom and Maddie Wachowski, in Green Hills, Montana. G.U.N. Director Rockwell arrives and recruits Sonic, Tails, and Knuckles (dubbed "Team Sonic") to help apprehend Shadow in Tokyo. However, he overpowers the three and escapes. Team Sonic meets with the now-Commander Walters, who informs them about Shadow's past. Suddenly, Dr. Ivo Robotnik's drones attack and fatally wound Walters, who gives Sonic a keycard before he dies. They decide to search for Shadow without G.U.N.'s help as Rockwell discovers the missing keycard and turns against them. Team Sonic encounters Ivo's assistant, Agent Stone, who denies involvement in the attack; they form an uneasy alliance with Ivo and track the stolen drones to the abandoned G.U.N. facility. As Shadow captures Stone and Team Sonic, Ivo meets Gerald, his long-lost grandfather and the mastermind behind Shadow's escape and the stolen drones. Gerald explains that the keycard is one of two needed to activate the Eclipse Cannon, an orbiting laser space weapon he designed for G.U.N., capable of targeting and destroying any location on Earth. He claims that he plans to use it to destroy G.U.N.'s headquarters in London, and Ivo agrees to join him. Shadow takes the keycard from Tails and activates a black hole to destroy the base as he, the Robotniks, and Stone leave. Team Sonic escapes using a ring portal and recruits Tom and Maddie to steal the second keycard from G.U.N.'s headquarters, contending with the Robotniks and Rockwell. Tom successfully obtains the keycard by disguising himself as Walters, but Shadow, buying into Tom's disguise and enraged at G.U.N., gravely wounds him, taking the key, allowing the Robotniks to launch the Eclipse Cannon. Enraged, Sonic abandons Tails and Knuckles, steals the Master Emerald, and becomes superpowered using the seven Chaos Emeralds contained within. Sonic confronts Shadow, who also absorbs the Chaos Emeralds' energy to become superpowered. Sonic eventually overpowers Shadow but relents upon realizing he was being consumed by revenge. Having a change of heart, Shadow agrees to stop the cannon. Aboard the Eclipse Cannon, Gerald reveals to Ivo his intention to destroy Earth and themselves to avenge Maria's death. A horrified Ivo attempts to abort the firing sequence, preferring to rule over humanity rather than destroy it, but Gerald destroys the command console. Tails and Knuckles arrive, and the three knock Gerald into the reactor core, killing him. Sonic and Shadow then team up to stop the Eclipse Cannon's destruction of Earth.
