Francis is a video-game obsessed chameleon in Super Paper Mario, who serves as the main boss of Chapter 3, The Bitlands. Francis is a large, anthropomorphic geeky chameleon, strongly personified as a highly stereotypical nerd, who kidnaps Tippi after declaring her a rare collectible by order of Dimentio. He is also known to have captured another pixl named Carrie. He then vows to take pictures of her and place them on the website, Digibutter.nerr, a forum filled with geeks and nerds of all sorts. He names Tippi 'Francine' and calls her that throughout the game. However, by the time Tippi and Count Bleck left, Francis calls her Tippi. Amongst his many obsessions, Francis, being an otaku (an anime obsessed person), he enjoys watching anime, collecting and/or playing video games, cats, and "hot babes". He lives in his own domicile, Fort Francis, where he has a large number of Meowmaids that are responsible for guarding the fortress as well as tidying his anime collections or recording his favorite television shows. Francis also has the habit of saying "hi-technicaaaaal!" if he believes something is cool, awesome, or "schweet."
Francis's lack of social skills disables him from being able to communicate with others face-to-face, and as a result has no offline friends. When he is confronted by Princess Peach, he is unable to talk directly to her, and instead plants the two into a dating sim named Swoon.exe, where they pass a short discussion.
Peach wants Tippi back, but Francis refuses to give her up, and the heroes must battle him. Francis has an array of attacks against the player: being an chameleon, he has ability to blend in with his surroundings allows him to become invisible and avoid attacks. This ability leaves the player with little time to attack him; that is, unless Mario flips into 3-D, where he can see Francis's moving shadow. His most devastating weapon is his tongue. Francis can swallow Mario and his friends whole and slowly damage them while inside him, or can use his laptop to summon upon an army of Meowbombs. He also has a camera, which he uses to temporarily blind Mario and his friends. Upon defeat he runs away, and yelling "Mercy!", he leaves the room. After this, Tippi is released.
After Francis' first defeat, Francis can not be found in Fort Francis. One of the Meowmaids says it is because Francis is in the hospital after he hurt himself playing one of his video games.
Francis can optionally be fought once more later on in Castle Bleck, after Mimi transports him to the castle to finish off the player. More specifically, the three remaining heroes (as Bowser was lost arguing with O'Chunks) could choose to fight him again after Mimi, disguised as the friendly Merlee, asked Mario which things he found most challenging, which always included an easy enemy, a hard enemy, or a helpful item. The hard enemy for Mimi's third and last question was Francis, and, if Francis was chosen for that question, Mimi (having Mario's input on what obstacles challenged him most) managed to place him in a room in Castle Bleck. Francis had apparently been watching one of his favorite television programs before being warped into the castle, and, despite his confusion, he yearned to have Tippi back so much that he talked himself into thinking that his Reclinatron 4500 chair had, manipulating his very dreams, warped him to Tippi. He then engaged battle once more with Mario and party, and, despite how later he was fought in the game, he had no different statistics or attacking methods, and therefore even the same amount of HP. He was, of course, defeated, and after his defeat he ultimately warped away, stating that he was going to simulate the battle on his computer to see what had kept him from winning.
If the player returns to Fort Francis after beating the game, Francis will show his greatest creation to them: Tiptron. However, because he is saving to buy Starship X-Naut Issue One, the player can purchase Tiptron from him for 999 coins. After the player buys Tiptron, he reveals plans to build Tiptron Mk. II, an improved version of Tiptron. Francis then orders a Meowmaid to get him some Nibble-Ums to fulfill his hunger before he begins his work. Francis is never shown to have finished Tiptron Mk. II, but it is implied that he did eventually. It is notable that Francis calls her Tippi instead of Francine as the player is given the offer of buying Tiptron.
In addition to Starship X-Naut Issue One, Francis is the source of many other references to the other Mario games. As well as a Starship X-Naut TV show, there is also a Starship X-Naut: Space Bloops videogame, as well as another game entitled Larry Koopa: Zombie Heartbreaker, presumably starring Larry Koopa, which Francis was hoping to purchase. The Grodus Chronicles, another X-Naut-related television show was also mentioned, as was an anime featuring Tubba Blubba (of the first Paper Mario): The Blubbening. Francis owns several dolls of Princess Peach, Whacka, Petuni, Punio, Vivian, the Yoshi Kid in all colors, a Bub-ulb and Pennington from Paper Mario: The Thousand-Year Door, and he has posters of Petuni, Lady Bow and Bootler. On his shelf, players will also find multi-coloured Yoshi Eggs next to the aforementioned dolls. He also wants an Excess Express train set, a Ms. Mowz doll with "real smooching action", a product called Cyborg Wart, a Magnus von Grapple action figure, and a Tanooki Suit made with real Tanooki fur. Francis also has an NES, an indigo GameCube, an SNES, a Nintendo 64, a Game Boy and a Virtual Boy on his shelf. When the player flips Mario into 3D, they will also find a large television screen with a Wii and a Wii Remote.
Francis is known to have a mother, who is unseen and unnamed. Francis will mention his mom in an optional event found towards the end of Fort Francis. After starting up his Swoon.exe program, the first question Francis asks to its subject of Princess Peach (after he explains the dating simulator) is "What is your name?". Peach can then choose from three answers, the second (and most passive) of which is "Tell me your name first!". Francis will then obey her order, noting to himself that Peach is "a stickler for etiquette" and recalling his similar mother. Remembering his mom also makes Francis level up in passion for unknown reasons. It is also hinted that he has no girlfriend or wife because the only people that can enter his room are himself and hot babes meaning he wants a date.
