20th Century Boy

20th Century Boy is the Stand of Magent Magent, featured in Steel Ball Run.

Appearance
20th Century Boy appears generally like a hollow piece of armor, composed of a headpiece, two large shoulder pads from which hang two long, branching straps, and a shell at its back from which grow two more comparatively plain straps. Blank-eyed, its head bears two long, vertical antennae; a bolt runs through it from shoulder to shoulder; and it is marked by a motif resembling a small hand of three simple fingers, both on its head and at every end of its branching straps.

20th Century Boy is purple and cyan in the colored manga.

Ability
20th Century Boy has no special offensive capabilities, but its defense is exceptional. Although Magent Magent must be immobile in its invulnerable state, there is no way to bypass its defense.

As a result, only sneak attacks and returning the immobility against Magent Magent are effective against him.

Absolute Defense
Whenever Magent Magent activates 20th Century Boy and kneels to the ground, he becomes impervious to all damage.

All energy and incoming projectiles are redirected away from Magent Magent into the earth or air, making him immune to any damage, be it from Stands attacks, Steel Balls, bullets or explosions. It even prevents Magent from other dangers like drowning. 20th Century Boy's ability has been explained as belts stretching out like earthing wires, and redirecting all the energy from enemy attacks into the ground.

Demonstrated first against blows from Gyro's Steel Balls, this ability proves effective in the direct midst of attack when a bullet already beginning to pierce its user's face is deflected.

The downside of this ability is how it is activated, requiring Magent Magent to expose himself or stay immobile. Thus, one can lure Magent into dropping his guard and know that he won't be able to react to sneak attacks fast enough, or take advantage of Magent's immobilization to tie him into a precarious situation and thus trap him.

Trivia

 * The name of his Stand, "20th Century Boy," has various connections to Magent Magent's character, one of these being his constant ramblings about how if only he had the newest upcoming devices like an airplane, his job would be much easier. Effective airplanes were first built during the 20th century, this relates to Magent as he basically wishes to live like a "20th century boy" himself, by utilising advanced technologies.
