As a Materialized, it possesses the ability to bind itself to a boat and transform it into a massive Freighter. Its user is then capable of manipulating the ship at will.
Strength binds itself to a small boat and takes on the appearance of a massive freighter named "Big Daddy". Although seemingly abandoned, all of the equipment is in good condition.[1]
Personality
Strength's tarot card
Strength lacks its own will as it is completely under the control of Forever. It represents the tarot cardStrength, which symbolizes resilience, compassion, and confidence.[2]
Abilities
Disguised as a freighter, Strength is an incredibly powerful Stand used to take its enemies by surprise. It almost killed the entirety of the Joestar Group at once.
However, it is burdened by the cockiness of its user, Forever, who likes to brag and thus expose himself to retaliation.
Ship Manipulation
The whole ship is under Forever's control
Strength is capable of binding itself to a small boat and transforming it into a gigantic freighter.[3]
While Strength is bound to an object, Forever gets unquestionable psychic control over it. Even objects, such as electrical cords, bolts in the hull, and the very floors and walls themselves are bent and twisted to the beck and call of Forever's will. 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.[2][4]
Strength's concept was inspired by the real-life ship Mary Celeste, which was famously found adrift and mysteriously abandoned in the Atlantic Ocean.[5]
In appearance, Strength resembles the possessed killer freighter from the 1980 horror movie Death Ship. In the OVA, many shots of Strength's interior and machinery also are similar to the ones seen in the movie.
