The Emerald Detector is an object that appears in the Sonic the Hedgehog series. It is a portable device, able to track and locate emeralds infused with Chaos Emerald energy, such as the Chaos Emeralds, the Master Emerald and Emerald Shards. For the ongoing hunts for such emeralds, the Emerald Detector is a valuable device and has been used by heroes and villains alike.

History[]

Sonic the Hedgehog 3[]

In Sonic the Hedgehog 3, an Emerald Detector name the Jewel Radar (ジュエルレーダー Jueru Rēdā?) was developed by Tails. This device would detect a reaction from the Master Emerald after the Death Egg landed on Angel Island, prompting Sonic and Tails to head out and investigate.[1]

Sonic Riders[]

Sonic Riders Heroes intro 3

An Emerald Detector, from Sonic Riders.

In Sonic Riders, an Emerald Detector was used by Team Sonic. This one resembled a stopwatch with a radar screen, a button display on the bottom and a small antenna on top. Its screen could display the surroundings in 3D, allowing for better location of the Emeralds.

Team Sonic used the Emerald Detector to track a Chaos Emerald to Future City. While experiencing interferences, the Emerald Detector pinpointed an Emerald in the possession of the Babylon Rogues.

Sonic Rivals 2[]

In Sonic Rivals 2, Eggman Nega had a Ring-powered[2] Emerald Detector. The Master Emerald, which Nega had stolen, was inserted into this device. This device was taken from Nega by Knuckles and Rouge who used it to find Emeralds as well;[3][4] Knuckles sought the Master Emerald while Rouge looked for the Chaos Emeralds. At the end of their hunt, where Rouge found the Chaos Emeralds thanks to the Emerald Detector, the detector was damaged and Knuckles discovered the Master Emerald inside it, much to his dismay.[5]

Other game apperances[]

Sonic Runners[]

In Sonic Runners, an Emerald Detector, also called a Master Emerald detector, was used by Dr. Eggman to track down the Emerald Shards of the Master Emerald. This device was a rectangular red pad with a round green radar screen, buttons on the edges and an antenna on top.

Early on, the Emerald Detector was used by Dr. Eggman to track Team Sonic's movements, who were also hunting Emerald Shards, but when Eggman confronted them, he lost the Emerald Detector to the heroes, who used it to find the remaining Emerald Shards.

The Emerald Radar, from Sonic the Hedgehog 30th Anniversary.

In the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing, an Emerald Detector (called the Emerald Radar[6]) created by Tails was accidentally dropped by him in Spring Valley Zone when he headed out with Sonic and Knuckles to find the Chaos Emeralds. The Emerald Radar was then found by Amy Rose, who used it to track down a Chaos Emerald in Summer Falls Zone and another one in Autumn Forest Zone alongside Mighty and Ray. Later, after all the Chaos Emeralds were secured, Amy would give the Emerald Radar back to Tails.[6]

Trivia[]

  • The Emerald Detector bears a few key similarities to the Dragon Radar from the Dragon Ball series:
    • They are both used to track down the prominent objects in their respective series; the Dragon Radar locates the Dragon Balls, and the Emerald Detector locates emeralds with Chaos Emerald energy.
    • The Emerald Detector's design is very similar to the Dragon Radar; in Sonic Riders its design looked nearly identical to the Dragon Radar, in Sonic Rivals 2 it would beep when near the sought out objects.
  • In IDW Publishing, the Marvelous Queen is shown to be equipped with its own built-in Emerald Radar.[6]
