Yosuke Hanamura/Persona
The gallant, young thunder: though born of nobility, Jiraiya's family was driven from their home by rivals. Desiring revenge but refusing to grovel at the feet of those who were born his equals, he instead chose the life of a bandit in a neighboring country to fund his ambitions. Gaining the respect of other freebooters with his daring and cunning, he unexpectedly found himself their leader and inspired them toward more chivalrous thievery. Tutored in the art of toad magic and shapeshifting by a mountain-dwelling immortal, he eventually mastered the ability to take on any appearance or gender, even the form of a frog. Though never able to reclaim his lands and restore his family's honor, tales of his bravery eventually attracted the attention of a beautiful healer named Tsunade who would become his wife. Due to his shapeshifting abilities it's impossible to completely account for all of the mischief he caused, and few -- friend or foe -- were ever aware of his daimyo heritage.
In battle, Yosuke's manifestation of Jiraiya possesses a diversity of skills that are difficult to pin down. Though a competent attacker that specializes in wind magic, the Disco Frog truly excels at confounding an opponent's ability to control the battlefield while allies take advantage of the chaos. Such uncompromising adaptability comes with a price: every action must be chosen with care, for dumb luck will not be there to catch Yosuke when he falls. The potential is there, but the wisdom to use it only comes with experience.
Its attire is either a dastardly ninja ruse designed to distract opponents while they're winded to death, or an artifact of Yosuke's terrible taste in fashion.
The latter is far more likely.
