The Persona universe (ペルソナ, Persona) refers to the Super Smash Bros. series' collection of characters, stages, and properties from the series of role-playing social-simulation games developed by Sega subsidiary Atlus. A sub-series of the Megami Tensei franchise, the games blend life simulation with dungeon crawling RPG elements of its parent series. This franchise, alongside its parent Megami Tensei franchise, is considered a flagship franchise for Atlus, helping to establish Atlus and the Megami Tensei franchise's popularity outside of Japan. Persona 5, released in 2016, is the single best-selling and most popular game in the franchise.
Following the positive reception of Shin Megami Tensei If..., a spin-off of the Megami Tensei series which saw the series' traditional post-apocalyptic setting replaced with a high-school setting, Atlus commissioned an experimental spinoff with a dedicated focus on the inner struggles of young adults. The first game in what would become the long-running franchise, Revelations: Persona, was released in 1996. Departing from the traditional first-person gameplay and post-apocalyptic setting of its parent series, Persona games take place in a modern metropolis and focus on a party of high school students, each wielding the power of "Personas". Personas are described as "masks to wear through everyday life", and bestow the user with a guardian entity which takes the form of a mythological figure and is capable of magic and other supernatural abilities. The games take heavy symbolism from Jungian psychology, as well as the tarot cards. Each game takes place in a separate locale and makes few direct references to its predecessor, though various Personas recur from game to game, as does the series' mainstay location "The Velvet Room" and its mysterious master Igor. Inevitably, the protagonists end up confronting the supernatural being responsible for the game's central conflict, and defeat them in combat in order to resolve it. More modern Persona games (Persona 3 and onward) place additional emphasis on "Social Links", a visual-novel like system where the player character converses with various NPCs, including their party members, and helps them through the struggles of their individual character arcs. In turn, the strengthened bonds of the Social Links grant the main character additional power, such as new Personas to wield or added inventory to shops.
Planning for Persona 5 began after the release of Persona 4, though full development did not officially begin until after the release of the puzzle game Catherine in 2011. The game's development was handled by P-Studio, an internal team within Atlus who were responsible for the core Persona series and Catherine. One early concept for the game was to incorporate an action battle system with real time elements. However, doing this would have meant throwing out everything the studio had cultivated over the course of the series, so the idea was scrapped on the spot. Rather, the team would refine what they already have built on, such as the Persona fusion system, as well as bringing back concepts from earlier Persona titles such as guns and the Negotiation system.
The original scenario for the game was to emulate a backpacking journey around the world with a theme of self-discovery. However, just as the team began solidifying this direction, the catastrophic 2011 Tōhoku earthquake and tsunami struck Japan. The aftermath of the disaster deeply affected director Katsura Hashino, who then decided to refocus the game's scenario on Japan to follow their mindsets after such an event. From that point on, the scenario would instead focus on the "adventurous spirit of the human mind," as Hashino put it, through the lens of the Japanese. To achieve this, the scenario adopted a more picaresque tone where the main characters were lovable misfits and rebelled against the conventions of society armed only with their wits. This became the basis for the Phantom Thieves of Hearts and "Social Links" were renamed to "Confidants". The party’s starting Personas also reflect this change, as most of them are named after famous outlaws and criminals such as Arsène Lupin III, Zorro, William Kidd, Carmen, and Pope Joan. The choice for the more stylistic user interface for Persona 5 came from the picaresque direction to reflect the rebellious nature of the Phantom Thieves. This did not come easy, as the team had to continuously test and adjust the UI until it achieved a good balance between style and clarity. Many critics and fans took note of and praised this UI, saying it complemented the themes of rebellion well and calling the game "effortlessly stylish" because of it.
After what amounted to a five-year development cycle, Persona 5 was released in September 2016 in Japan and April 2017 worldwide. The game went on to become Atlus's single best-selling title in Japan in just three weeks, as well as the fastest selling Persona game ever internationally. Critics praised the evolution of the game's combat, Social Links, and story and called it one of the best Japanese role-playing games of its generation and of all time. The game went on to receive many Game of the Year nominations throughout 2017 and placed highly in many outlets' "RPG of the Year" category. An upgraded version with additional characters, dungeons, and Confidants called Persona 5 Royal was released in Japan in October 2019 and was released worldwide on March 31, 2020.
The Persona series makes its Super Smash Bros. series debut as the first DLC franchise in the Fighters Pass Vol. 1.
