Paper Mario (series)

The Paper Mario series is one of the many of the Mario series. Four games have been released in this series: Paper Mario, Paper Mario: The Thousand-Year Door, Super Paper Mario, and Paper Mario: Sticker Star. Most of the games in the series are strictly RPGs, though Super Paper Mario is a platfomer with RPG elements. The four games have been released on separate consoles, the Nintendo 64, the Nintendo GameCube, the Wii, and the Nintendo 3DS.

Similarities between the games

 * In all the games, Mario has to fight one or more of his allies at least once. In Paper Mario he fights Lakilester, in Paper Mario: The Thousand-Year Door he fights Vivian along with her sisters and the tricked Goombella, Koops, Flurrie and Yoshi with Doopliss, in Super Paper Mario he fights Bowser and Mr. L (Luigi) twice each, and in Paper Mario: Sticker Star, each Wiggler Segment is fought.
 * In all the console games, Mario is able to temporarily transform into an 8-bit version of himself.
 * Each console game has someone telling a long story with Mario falling asleep. When he wakes up, the storyteller asks if he's been listening, followed by Mario lying by nodding. In Paper Mario, Madam Merlar tells the story. In Paper Mario: The Thousand-Year Door, Luigi and the shopkeeper in Twilight Town tell the stories. In Super Paper Mario, Merlumina tells the story.
 * All four games involve 1 or more giant Bloopers as a boss.
 * All four games involve a grassland setting followed by a fortress of some sorts during the first chapter or area in the game.
 * All four games involve an exotic world in the fifth chapter.
 * Additionally, Super Paper Mario is the only game where the fifth chapter does not feature a tropical island setting.
 * All four games has at least one game show event. In Paper Mario there was the 64th Trivia Quiz-Off, in Paper Mario: The Thousand-Year Door there was the two Super Fun Quirk Quizes, in Super Paper Mario there was "That's My Merlee!" Show, and in Paper Mario: Sticker Star, there was Snifit or Whiffit.
 * In all four games, the final boss is a powerful version of a member of the team of Super Paper Mario: in the first game is an invincible and giant Bowser, in the second one is Princess Peach possessed by the Shadow Queen, in the third one is a mixture of Dimentio, the Chaos Heart and Mr. L, and in the fourth one another invincible and giant Bowser.
 * All four games had a remix of the Super Star theme play somewhere. In Paper Mario, when Mario runs around a certain Candy Cane, the theme will start playing. In Paper Mario: The Thousand-Year Door, when playing the Bowser segments, if the player collects enough Meat in a level, Bowser grows huge and the theme plays. In Super Paper Mario, when the player obtains a Mega Star, the theme plays, and in Paper Mario: Sticker Star, the theme plays when the player grabs a Star.

Trivia
It is revealed in Mario & Luigi: Paper Jam that the Paper Mario universe exists as a book in the Mario and Luigi universe. In fact, the game's plot was triggered as a result of Luigi accidentally freeing all of the Paper Mario characters by opening their book and sending them into the Mario and Luigi world as a result of him being surprised by a mouse in Peach's Castle's attic.
