|Description||Standard Program appearance but lacking Identity Disc|
|Out of universe information|
Strays were rogue programs who lacked identity discs. During the rule of Clu, they would be rounded up by Guards and Sentries to be rectified. Sam Flynn was captured by Sentries when he entered the Tron System after it was found that he lacked a disc.
Strays often lost their memory in fits called glitches after being parted from their disc for too long. A notable example of a stray is Beck, a program who's disc was stolen. After recovering his disc, his memories returned.
