'''Kuaidul Velgear''' (クァイドゥール・ベルギャー ''Kwaidūru Berugyā'') is a character in the ''[[Yu-Gi-Oh! GO RUSH!!]]'' anime and the primary antagonist of the sixth arcand seventh arcs. He was the first [[Velgearian]] created by the [[OtesThe Creator (GO RUSH!! character)| Creator]] and thus the blueprint for the entire artificial race, and seeks to rebel against his creator by manipulating the people of the universe. To this end, Kuaidul explored various methods to transform people into "[[Kartumata]]" as the Velgearians had been created, both by manipulating [[MIK (organization)|MIK]] to transform people into cards and by giving "[[Darkness (Rush Duel series)|Darkness]]" cards to [[Duelist]]s to corrupt them.

Kuaidul dresses in light-colored clothing. He wears a long cream-colored coat with a grey lining strapped closed over his chest with a high collar and grey cuffs and armored pauldrons, a grey waistcoat, a dark maroon undershirt with golden thread at the throat, white pants, and metal calf-length boots lined with gold. Kuaidul wears a pink-bladed [[Velgearian ]] energy sword]] at his hip on a black belt and his [[Gavil Charger]] over his coat, between its two collars.

Kuaidul uses the personal pronoun "koregashi". This contrasts [[Yudias Velgear]]'s use of "soregashi"; "sorekore" refers to something close to the speaker, while "koresore" refers to something close to another person, or the listener being addressed. Notably, Kuaidul served as the narrator during the initial episodes and [[Yu-Gi-Oh! GO RUSH!! - Episode 052|episode 52]] of ''[[Yu-Gi-Oh! GO RUSH!!]]''. ==Decks=====Yudias's Deck==={{main|[[Yudias Velgear#Season 2]]}} When taking over [[Yudias Velgear]] during his [[Yu-Gi-Oh! Rush Duel|Rush Duel]] with [[Yuhi Ohdo]] in the [[Galaxy Cup]], Kuaidul uses his [[Main Deck|Deck]]. ===Mutsuba Town===In line with his "Project Cartios", Kuaidul literally uses the people of [[Mutsuba Town]] as his [[Main Deck|Deck]], 39 cards representing the 39 people he allowed to become aware of the [[Kuaidul Spacetime]], and the 40th being his own [[Signature card|ace monster]]: "[[Transamu Praime Armor Nova (anime)|Transamu Praime Armor Nova]]". Due to its nature, with most people being represented by their ace monsters (and those who are not by [[Spell Card|Spell]]/[[Trap Card]]s), Kuaidul's Deck contains no low-[[Level]] [[Monster Card|monster]]s, making it completely reliant on luck, an aspect which is criticized by the characters as a sign that it is incomplete. Notably, this is one of the few times a character's full Deck list is known. After realizing the truth behind the Kuaidul Spacetime, with the exception of "Armor Nova", [[Yudias Velgear]] takes this Deck and makes it his own. {{Decklist||normal monsters = * [[Black Luster Soljersey (anime)|Black Luster Soljersey]]<ref group=Notes name="george85">This card can be seen represented by [[George Jersey]] in [[Yu-Gi-Oh!

Rather than outright using cards from other characters' Decks, Kuaidul now uses [[LIGHT]] [[Attribute]] [[counterpart]]s of cards used by the people of [[Mutsuba Town]]. Also, in addition to including low-[[Level]] [[Monster Card|monster]]s, Kuaidul's high-Level monsters differentiate themselves from their original counterparts by being able to be [[Tribute Summon]]ed with 1 [[Tribute]] at the cost of permanently decreasing their [[Original ATK and DEF|original ATK]], something he dubs "Praime Tribute Summon". {{Decklist||normal monsters = * [[Praime Drake]]|effect monsters = * [[Praime Bandijo (anime)|Praime Bandijo]]* [[Praime Claw Girl (anime)|Praime Claw Girl]]* [[Praime Dian Keto (anime)|Praime Dian Keto]]* [[Praime Dwarf (anime)|Praime Dwarf]]* [[Praime Phantomite (anime)|Praime Phantomite]]* [[Praime Tractiger (anime)|Praime Tractiger]]* [[Praime White Panda]]<ref group=Notes name="drysaucer90">This card is [[Send|sent]] from Kuaidul's [[hand]] to the [[Graveyard]] by the [[effect]] of "[[Praime Dry Saucer]]" in [[Yu-Gi-Oh!
