According to the earliest accounts of the tale, "Stingy Jack" was an Irish farmer who persuaded the devil not to take him to hell. When he was refused entry into heaven, he wandered the earth as a turnip-headed (or pumpkin-headed) soul who would come to be called "Jack of the Lantern," or so says the legend. Jack-o'-lanterns are carved by children and enthusiasts alike on Halloween. The tradition can also be thought to help guide the lost soul himself.
The legend, however, goes back further than the term itself. Jack-o'-lantern or some variation thereof was at the height of usage in 17th century Europe. Simply put, it meant "the guy with the lantern." Later the term would almost exclusively be used as slang in reference to the will-o'-the-wisp phenomenon, or ignis fatuus; due to the appearance of a far off person carrying a lantern.
Jack-o'-Lantern is second of the three Jack brothers. He is one of the most common demons in the series, appearing in nearly every game. He still retained the more traditional "Jack O'Lantern" name in the earlier English localizations. Since Shin Megami Tensei III: Nocturne and subsequent localizations, "Pyro Jack" has occupied the English naming with no official explanation from Atlus. The name change, however, makes him more comparable with his in-game brother, Jack Frost, in terms of their signature elements of fire and ice. The name "Jack-o'-Lantern" has been eventually restored in Persona 5, Persona 5 Strikers, Shin Megami Tensei III Nocturne HD Remaster, Shin Megami Tensei V, and most games and remakes afterwards, suggesting "Pyro Jack" was a localization compromise for text limitation of the user interface.

Shin Megami Tensei IMAGINE[]
"Imps of fire that appear in English legends. Jack-o'-Lantern is a soul who lived a decadent life and was refused entry into the afterlife. Taking pity on him, a demon placed a small bit of hellfire in a lantern made from a turnip to provide light for him as he wanders through the darkness. In the world of the living, he sometimes serves as a guide for travelers. Jack-o'-Lantern is good friends with Jack Frost. Some Demon Busters claim to have seen them team up as Demon Buster-busting duo Lantern Frost. Today, Jack-o'-Lantern is known as the pumpkin ghost of Halloween. It is believed that this change from turnip to pumpkin came about when the custom of Halloween first came to the United States, because Americans found that pumpkins were brighter and easier to carve than turnips."
