The Light Core[1] (ライトコア[2] Raitokoa?) is an object that appears in Sonic the Hedgehog (2006). They are orbs invented and researched by Rimlight in hopes for developing a cleaner energy. They are released by certain enemies and are used to charge the Action Gauge.


Essentially, Light Cores resemble small, glowing crystalline orbs. Light Cores are usually orange, but can also be green as seen in Town Missions and Action Stages, such as Aquatic Base and Wave Ocean.


The technology for Light Cores was developed as a robotic power source by the Rimlight Corporation of Soleanna. Dr. Eggman, however, raids their offices in New City to steal the technology and use it in his own robots.

In gameplay, Light Cores can fill up a small part of the Action Gauge, akin to the Chaos Drive. They are released from enemies such as Iblis' minions, shadows, and Mephiles's monstrous form once they are destroyed, after which they are absorbed by the playable character.
