X-Antibody Indicator

The X-Antibody Indicator (Ｘ抗体インジケーター X-Koutai Indikeetaa), also referred to as the XAI System (ＸＡＩシステム Sai Shisutemu) is a system which displays the status of the X-Antibodies. If the XAI system is activated, via the Pendulum X, and it detects the X-Antibody present, it will begin to alter the Digimon itself, resulting in an X-Antibody Digimon.
