20th Century Boy

20th Century Boy is purely a defensive stand. It takes the form of a humanoid armor that covers the user's upper body. While crouching in a still position, with palms touching the ground, the user is completely immune to attacks. Even destructive blows like Gyro's steel balls are rendered useless. The force of the attacks are redirected from the body to the ground where it is dispersed. Projectiles are simply deflected away from the body. It even seems the stand can be activated in the middle of being attacked, as a bullet had already begun to pierce the user's face when the stand's ability deflected it away. The stand is only in effect when the user is still, and has no special offensive abilities.

When sunk on a river, Magenta Magenta, reveals that his stand can protect him for drowing and even keep him alive without breathing as long as he keep quiet.

The user is Magenta Magenta, and the stand's name comes from the T. Rex song, 20th Century Boy.
