Harmonics Messiah, the first stride unit that served as a focal character in last year's Cardfight!! Vanguard theatrical film, Neon Messiah. In the film Ibuki sought to take Harmonics for himself in order to erase the card game entirely, but only achieved his goal after he had already given up on destroying Vanguard. Harmonics then transformed into the grade 0 Neon Messiah. Neon Messiah will debut in the card game as the first vanguard for Messiah of the Fateful Star, and while Harmonics is the only card to have no original clan, Neon is a pure Link Joker. In the card lore Harmonics was summoned to purify the Deletors' home planet Brandt of Link Joker's influence, and its artwork depicted it holding Cray and Brandt on its shoulders. The trial deck's Messiah unit carries a similar theme, while the booster set's Messiah appears empty.
G-TD05 makes use of a complex visual pun; the name is written with the kanji 宿星 Shukusei "star of fate" but with the radical for "sun" 日 substituted by an illustration of a partial eclipse. A popular but grammatically incorrect alternative translation is "Messiah of Zodiac." Shukusei can refer to a singular zodiac (Pisces, Aquarius, Leo et al.) but not the entire twelve signs at once; for this 獣帯 Shuudai is used. Shukusei is also used in relation to the Chinese system of constellations. The trial deck is referring to a singular star with governance over fate, not a Zodiac sign that embodies a series of interconnected stars. G-BT03's ryuusei is a homophone for "shooting star," while hadou is a form of martial law that is also written with the characters for "Way of Supremacy," just as the samurai code Bushidou is written "Way of the Warrior" and the Japanese religion Shintou is written "Way of the Gods." Of note is that the kanji for Supreme Way has a black X crossed through it, which resembles another symbol found on the Malefic Deletor logo.
rise to power in professional play, to the point of being considered for restriction. While post-BT02 tournament results have seen “The X” all but disappear from the top spots, that has not inhibited strong turnouts from Overlord cardfighters, who regularly account for the second or third greatest deck representation.
