They're Kamen Rider series that has the primary Kamen Rider as a detective and involve them solving case that involves the antagonists. The main characters of each series are very well liked and brings a very cool or should I say hard-boiled feeling to them.
OOO is the series after W so if you want to watch the Kamen Rider seasons in order watch OOO after W.
Not long after the events of Kamen Rider Gaim, Kouta and Mai, who are now ruling over a new planetoid as gods, are attacked by Megahex, a cybernetic being with ambitions of making the whole universe one with it's self in a symbiotic manner. Mai is taken prisoner by Megahex who then chases Kouta back to earth where he briefly fights Megahex to try and save Mai with the help of his old friends from Zawame City, but after struggling to hold their own against Megahex's army which is commanded by restricted versions of some of their old enemies. Meanwhile in another part of the Japan, Shinnosuke and the rest of the Special Investigation Unit are dealing with Phantom Thief Ultimate Lupin, a mysterious criminal who is running wild in the city. Moments after the case is solved, Megahex's invasion of earth expands to the rest of Japan and after a moment of confusion, Shinnosuke and Kouta team up to stop Megahex and save Mai along with the rest of the planet
No spoilers but everything related to Ruan Lanzhi's character is extremely similar to Suda Masaki's. Even the damn good relationship between the two male leads. All Rider universes have tons of odd monsters including ghosts and especially W has a lot of the same similar angst and hot people getting in trouble and hurt and crying their eyes out. The vibe of W gets just as dark at one point even though on the whole it's funny and lighter there are still some episodes that will get to you.
Like Kamen Rider × Kamen Rider W & Decade: Movie War 2010, Movie War Core is split into three parts. The Kamen Rider W portion of the film is titled Kamen Rider Skull: Message for Double. The story, taking place after the series epilogue, features Akiko Narumi preparing for her wedding before considering canceling it when the Futo Kamen Riders are distracted by the Pteranodon Yummy, who has somehow acquired the Memory Memory. The Pteranodon Yummy uses these powers to reveal to Akiko how her father and Shotaro's mentor, Sokichi Narumi, became Kamen Rider Skull with Shroud's aid.
The Kamen Rider OOO portion of the film is titled Kamen Rider OOO: Nobunaga's Desire. The Kougami Foundation has discovered the mummified remains of Oda Nobunaga and has created a Cell Medal-based homunculus of the man with his memories. Dubbed Nobunaga, he runs from the Kougami Foundation and into Eiji Hino's care. However, Nobunaga attempts to resume his conquest of Japan while targeting the descendants of those responsible for his downfall. But when forced into becoming a mindless Greeed, Eiji must stop Nobunaga before it is too late.
In the final portion of the film entitled Movie War Core is convergence of the two films that brings the casts and characters of W and OOO to fight the evil energy-based giant Kamen Rider Core.
