Crisis City
Tails developed the bio-scanner as a means of reading Sonic's biometrics as he ran so that they could discover how his speed countered the Metal Virus. Tails decided that he would analyze the data collected from the bio-scanner at his lab in Central City since the computer in Restoration HQ would not be able to handle such data.

The Last Minute
Sonic began using the bio-scanner and ran as far as he could, nearing Barricade Town.
