As the launch of Fire Emblem: Fortune's Weave approaches, Nintendo has continued to unveil new characters through trailers and social media. Notably, the game's Japanese Twitter account has provided early glimpses into the game's roster, introducing a mysterious swordsman named Jester. This character's dark aesthetic and unsettling backstory have sparked particular interest from fans.

According to information translated from Japanese, Jester is a masked gladiator known for his erratic behavior and a nickname that translates to "Hell's Jester." He reportedly enjoys facing opponents who show fear and possesses an ability that grants increased damage after a successful dodge. The character design has resonated with players who favor more unconventional archetypes, deviating from the typically wholesome characters that have previously attracted the author's attention in the series, such as Jakob in Fire Emblem Fates and Claude in Fire Emblem: Three Houses. The desire to pursue a romantic relationship with Jester highlights a player's appeal for characters who embody a "we can be worse together" dynamic rather than a "I can fix him" mentality.

Beyond Jester, Fortune's Weave has also drawn praise for its diverse cast, particularly the inclusion of numerous characters of color. This stands in contrast to many AAA games, which often feature only a limited number of such characters. Specific characters like Nocturna, a swordswoman from a militaristic tribe seeking life in the capital, and Nudine, a former mercenary with a strong sense of justice, have been highlighted.

The presence of Seteth, a character from Fire Emblem: Three Houses, has further fueled speculation about Fortune's Weave's place in the overarching timeline, with ongoing debates as to whether it serves as a prequel or sequel. Seteth is described as an eccentric traveler from the distant land of Fódlan, accompanied by a cat-masked priest named Orhel, and known for his meddling nature. His return, along with other characters such as Diego, a tribal youth loyal to Orhel, and Bertrand, a formidable gladiator known as the "White Haired Oni," adds to the intricate lore players anticipate exploring.
