Funny Dark Rabbit

Etymology & Trivia
Funny Dark Rabbit is a combination of Funny Rabbit (the favorite cartoon character of Pegasus J. Crawford in the Yu-Gi-Oh! Duel Monsters anime/manga) and Dark Rabbit (a similar monster played by Pegasus in the anime/manga).
Pegasus was inspired by various scenes from Funny Rabbit in which the titular character was able to avoid being hit by bullets fired from a gun in a humorous fashion, leading to him inventing Toon World and Toon Monsters—which behaved in a similar way in the anime/manga.
Its effect of being treated as a Toon Monster while Toon World is on the field (and of other monsters in this set) is a reference to how the original Toon World behaved in the anime/manga: it would turn any monster on the player's field into a Toon Monster—rather than Toon Monsters being separate cards from the originals, like in the physical card game.
Comic Cat
Etymology & Trivia
Comic Cat is a reference to the similarly named Copycat—originally a Magic Card played by Pegasus which allowed itself to be turned into a copy of any card played by the opponent.
Its name is also a reference to Comic Hand—another Magic Card played by Pegasus, in the Yu-Gi-Oh! GX anime.
Evil Box
Etymology & Trivia
Evil Box is a reference to the similarly named Fusion Monster Devil Box—which in its original depiction was a regular Main Deck monster rather than a Fusion Monster and, in the manga, a Level 6 monster (same as this card).
Its color scheme and artwork showing it holding a scythe are references to the color scheme Devil Box had and the weapon it used to attack with in the anime, respectively.
Mind Scan/The Eye That Sees Through the Heart
Etymology & Trivia
Mind Scan is the name Pegasus gave to the ability granted to him by the Millennium Eye—which allowed him to look into people's minds and which he used to accurately predict the plays his opponent would make during the Duel.
The artwork is a reference to Pegasus's second Duel against Yugi Muto, during the Duelist Kingdom tournament—and the cards displayed in the opponent's hand are further references to the cards played by Yugi during that Duel, as well as the Mind Shuffle strategy both Yugis utilized to counteract Pegasus's Mind Scan.
Witchcraft Walpurgis/The Witches' Hallowed Night Procession
Etymology & Trivia
Walpurgis is a reference to the German Walpurgishnacht (Walpurgis Night)—the eve of the Christian feast day of Saint Walpurga, an 8th-century abbess in Francia, and is celebrated on the night of April 30 and the day of May 1. Saint Walpurga was hailed by the Christians of Germany for battling "pest, rabies, and whooping cough, as well as against witchcraft."
Devoted Ogre of Unchained Destruction - Shara
Etymology & Trivia
Devoted Ogre of Unchained Destruction (Hakaishiki) is a play on the Japanese word for "style" or "ceremony" (also pronounced as shiki)—but with the kanji ki meaning "ogre" or "oni" added next to it.
Shara is a shortening of Sharvara—one of the two Hindu mythological watchdogs associated with Yama, the Hindu and Buddhist god of death and justice.
Netherworld Magistrate of Unchained Destruction - Kamura
Etymology & Trivia
Kamura comes from Ono no Takamura—a Japanese calligrapher and poet of the early Heian period. He was the subject of a number of odd stories and legends, the most famous of which claimed that, every night, he would climb down a well to the underworld and help Yama in his judgments.
Skyblaze Demon of Unchained Destruction - Yama
Etymology & Trivia
Skyblaze Demon (Enmaten, written with the kanji for "flame," "demon," and "sky"/"heaven") is a play on the fact Enmaten (written with a different first kanji) is the Japanese name of the god Yama (as protector deity of the south in esoteric Buddhism).
