The bio-scanner,[1] also known as the data analyzer,[2] the data-reader,[3] or the data recorder,[4] is an object that appears in the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing. It is a sensor that reads the biometrics of the person who wears it.



The bio-scanner is an orange, white and gray donut-shaped bracelet. It has a small green screen on it.

Powers and traits

The bio-scanner has a built-in sensor that is able to read the biometrics of a person once they engage in some sort of exercise.[5]


Crisis City

Tails developed the bio-scanner as a means of reading Sonic's biometrics as he ran so they could discover how his speed countered the Metal Virus. However, the computer needed to analyze data collected from the bio-scanner was in his lab in Central City.[5]

The Last Minute

With the bio-scanner on his arm, Sonic began running as far as he could, finding that the device was working exactly as intended. To make the device even more important, it would serve as a backup in case something happened to Tails' lab. Unfortunately, the bio-scanner was destroyed by Sonic when he destroyed Dr. Eggman's Egg Mobile at Barricade Town. With Tails' lab having overwhelmed by Zombots as well, the heroes' only chance to find a cure for the Metal Virus was lost.[3]
