Strength

Strength is the Stand of Forever featured in Part III: Stardust Crusaders.

Appearance/Personality
Strength is a stand whose real appearance is never seen. It is bound to a small yacht, which is then transformed by the stand into a gigantic freighter named "Big Daddy" that Forever uses to cross the ocean. As a massive ocean liner, it is the largest stand ever seen. It has absolutely no will since Forever has absolute control over it. It represents the Tarot Card Strength, which symbolizes a challenge to fight, strong will and hidden potential .

Ability
Control: Strength is capable of binding itself to an inanimate object and bringing out its true potential. When bound to a ruined yacht, Forever was able to transform it into a gigantic freighter. It is possible that Strength can have this effect on any vehicle or even any inanimate object. While Strength is bound to an object, Forever gets unquestionable psychic control over it. Even objects such as electrical chords, bolts in the hull, and the very floors and walls themselves are bent and twisted to the beck and call of Forever. This power can be used to surprise attack those who board the yacht and also allows Forever to travel through the ship's walls and floor as if they were liquid.

Trivia

 * According to JOJOVELLER, this is inspired by the famous Mary Celeste.
 * In appearance, Strength resembles the possessed killer freighter from the horror movie "Death Ship". In the OVA animation, many shots of Strength's interior and machinery also are similar to the ones seen in the movie.
