|“||Brrrrooo ha ha ha ha... A touching scene, to be sure.||„|
Bonechill is the main antagonist of Chapter 7 in the video game, Super Paper Mario. He is a gigantic, blue semi-skeletal dragon with six gray feathered wings (resembling the wings of the Nimbi species) and a dark goldenrod-colored cannon for a lower limb and a black spiral tail, who commands the cold, and was after a pure heart in the Overthere (the Super Mario Bros. universe's equivalent for Heaven alongside the realm's benevolent inhabitants/dead good souls called Nimbis representing angels).
Bonechill, who was a former Nimbi, was once held below the Underwhere (the Super Mario Bros. universe's equivalent for Hell or the underworld), but was released by an earthquake, and entered the Overthere with several demons called Skellobits (the dead who were evil in life and sent to suffer among the game-overed). He attacked Grambi, King of the Overthere, before Mario, Peach, Bowser, and Luigi arrived to stop him. Bonechill revealed to Luvbi, Grambi's daughter who was traveling with Mario, that she was the eighth and final Pure Heart, turned into a Nimbi (angel) by Grambi and Jaydes (Queen of the Underwhere) to hide it from evil entities like him. Mario, Peach, Bowser, and Luigi fought Bonechill and defeated him. Bonechill was destroyed, shattering to bits.
Bonechill has 80 HP. He can breathe ice to freeze Mario and his allies, and make icicles fall from the ceiling. He also shoots icelike missiles from his cannon. To defeat him, you must grab icicles or missiles using Thoreau, and throw them at his head. Alternately, Luigi's Super Jump can be used to defeat him.
|“||Oh, you dear, ignorant child.... You really don't know a thing, do you? How charming!||„|
|~ Bonechill mocking Luvbi.|
|“|| Bonechill: The pure heart was hidden ingeniously to keep it away from evil sorts like me... Grambi...changed the pure heart into a Nimbi....that he called his own daughter!|
Luvbi: Ha ha... Th-That is just silly... My mother and father....
Bonechill: Oh priceless! You really think Grambi pays an ounce of attention to you out of love?
|~ Bonechill revealing (and exaggerating) the truth to Luvbi|
|“|| Luvbi: Father, sayest something!|
Grambi: L-Luv...b...bi... Unnghhh...
Bonechill: Brrrrooo ha ha.... The old fool can weigh the sins of others, but not his own....
|~ Bonechill showing himself completely heartless, making fun of Grambi while he is very emotional.|
|“||Many thanks for delivering the Pure Heart. Once I deal with you, none can stop me...I shall be INVINCIBLE! Please, as your game ends, remember it is an honor to have it ended by my talons!||„|
|~ Bonechill's words before the boss battle.|
|“||How... Impossible... How could you tiny worms...destroy...a master...of the cold dark?!||„|
|~ Bonechill's last words.|
- Bonechill with his Nimbi wings is inspired by the Biblical story of Lucifer, the renegade archangel who is also now known as Satan and The Devil after he betrayed God and became exiled from Heaven. Furthermore, in the Inferno (of Dante Alighieri's epic Italian poem known as The Divine Comedy), Lucifer (now known as Satan) is depicted as a giant, six-winged blue beast imprisoned in ice in the deepest circle of Hell filled with the frozen souls of traitorous sinners.
- This is all paralleled by how Bonechill has six wings, was imprisoned deep below the Underwhere, and is a self-styled "master of the cold dark" who is "something of an evil celebrity in certain circles of the Underwhere".
- Similarly, his release during an apocalyptic event (the emergence of The Void) may be derived from the Bible's Book of Revelation, where Satan escapes from hell and he and his army fought and were defeated by the forces of heaven.
- In the Japanese version, Bonechill used the archaic "zansu" conjugation of the auxiliary verb "gozaimasu" at the end of each sentence, which is typically used to characterize older, snobby, social-climbing females in fiction.
- Bonechill is one of the two bosses of Super Paper Mario in whose looks change as the player damages him; his scales begin to fall off as his HP declines. The other is Count Bleck's minion Mimi, who gradually loses her legs over the course of the battle.
