Infinite

A mercenary empowered by the Phantom Ruby who shatters reality with illusions to serve Doctor Eggman.

Infinite is a mercenary introduced in Sonic Forces, serving as Doctor Eggman's newest lackey after conquering most of the world alongside him. Empowered by the Phantom Ruby, he defeats Sonic in an opening confrontation that leaves the hero imprisoned aboard the Death Egg. His arrival marks a darker tone for the franchise, introducing psychological warfare where villains like Shadow and Chaos are revealed to be illusionary doppelgangers created to bolster Eggman's army.

Quick Facts

Affiliation: The Eggman Empire
First appearance: Sonic Forces

Lore & Background

Infinite was originally a leader of the Jackal Squad, a mercenary group eliminated by Shadow the Hedgehog during a reconnaissance mission. Humiliated after being called "weak" and unable to handle the pain of that insult, he covered up his past and gained power from the Phantom Ruby, rechristening himself as Infinite. This transformation occurred roughly one month before the main plot begins. He is not a hedgehog but a former Jackal Squad leader who now serves the Eggman Empire. His primary ability involves using the Phantom Ruby to create illusionary doppelgangers of villains like Shadow, Chaos, Zavok, and Metal Sonic, allowing for limitless numbers to be mass-produced. These illusions serve as a psychological weapon; Infinite demonstrates this by manipulating memories in Green Hill Zone, making Shadow believe Rouge is talking nonsense and that E-123 Omega is still alive despite being badly damaged.

Reader's Guide

Infinite functions as a primary antagonist whose threat relies on deception rather than just physical strength. Players encounter him first as the force that incapacitates Sonic, setting the stage for the resistance's formation. His gameplay role involves testing players' ability to distinguish reality from illusion, particularly in levels where he manipulates the environment or creates fake allies and enemies. To defeat him, players must navigate through his illusions, such as the flashback sequence sent to Shadow in Episode Shadow DLC. In the final confrontation, Infinite is defeated by the combined efforts of Modern Sonic, Classic Sonic, and the Avatar. His presence is crucial to the plot's twist regarding the false villains and the ultimate threat of the second sun, which is only averted by the Rookie's intervention before the final battle with Eggman.
