First teased during the screenings of Episode Of Chopper, Strong World was immediately treated as a big deal, not only as was the tenth film for the series, but it was also made to celebrate the 10^th anniversary of the TV anime, and for the occasion Eiichiro Oda himself wrote the script, instead of just providing character designs and approving story ideas as he did for the previous movies.

Also, in what would become a trend for future One Piece movies, Strong World features an original villain that was an acquaintance, crewmate or contemporary of Gol D. Roger, and previously was detained in the Impel Down prison complex. That alongside making the Marine (or the World Goverment aligned) characters more prominent – if not integral – to the story at hand.

The villain here is the pirate Shiki, dubbed “The Golden Lion” due to his mane, a legendary pirate from the Golden Era that escaped from Impel Down by cutting off his legs, and had basically vanished from existence, only to show up 20 years later in order to take revenge on the entirety of East Blue, and force the Goverment into surrender by using genetically enhanced animals, engaged into a constant battle for survival over the islands (the titular “Strong World”) that fly thanks to Shiki’s Devil Fruit ability.
