When the Nocturnus Clan returned to Earth to escape from the Twilight Cage, they set up signal projectors in Green Hill Zone that could control the native animals. As such, the Enraged Armadillos and the other animals in Green Hill Zone became aggressive, and began attacking anyone who got nearby. In the side mission "Stop the Signal", Sonic and his team destroyed the signal projectors, resulting in the Enraged Armadillos and all the other animals in Green Hill Zone returning to normal.
The Enraged Armadillos can only be encountered in Green Hill Zone. Their basic attack is ramming into their opponents. They possess no POW moves.
