VRAINS]]". These monsters are respectively the signature cards of [[Yugi Muto]], [[Jaden Yuki]], [[Yusei Fudo]], [[Yuma Tsukumo]] and [[Yuya Sakaki]], the previous protagonists from the first five series of the '' anime** As a [[Link Monster]], specifically scenes depicting it is the first signature card of a main protagonist about to not possess either a [[Level]]/[[Rank]] or a [[DEF]].*** Assuming that each [[Link Rating]] represents 500 DEF, this card would then be represented with 2000 DEF.** As a Link 4 Monsterattack, where it is the first protagonist monster that cannot be summoned with 2 "sacrifices".*** The first time this card's summoned, however, is with '''2''' Link 3 Monsterschanges color from blue to red.

* This monster is named after a the [[wikipedia:Firewall cover card]] of ''[[Code of the Duelist]]'', and is also one of the cover cards of ''[[Ghosts From the Past (computingset)|firewallGhosts From the Past]]'', ''[[LINK VRAINS Box]]'', a network security system in computing that monitors and controls the incoming and outgoing network traffic based on predetermined security rules.** Therefore''[[Mega Pack 01]]'', this card can represent Yusaku's actions as Playmaker against '[[The Knights of HanoiPrismatic Art Collection]]'', and ''[[25th Anniversary Tin: Protecting the Virtual World against any threat that menaces itDueling Heroes]]''.

* This card was monster appears in the first artwork of "[[Link 4 Monster Cards|Link 4 monsterCynet Circuit]] to be released."

* This card has 2 downgraded is named after a [[Link 2 Monster Cardswikipedia:Firewall (computing)|Link 2firewall]] counterpart: "[[Proxy Dragon]]" , a network security system in computing that monitors and controls the incoming and "[[Security Dragon]]"outgoing network traffic based on predetermined security rules.** Their combined This card reflects Playmaker's actions of protecting [[ATKLINK VRAINS]]against any threat, especially the [[Link Rating]]s and [[Link ArrowKnights of Hanoi]]s equal those of this card's.

* This monster and "card has some [[Decode Talkercounterpart]]" are the first ace monsters of a spin-off protagonist whose s:** 2 downgraded [[TypeLink Monster|Link]] is neither -2 forms: "[[Proxy Dragon]] nor [[Warrior]], thus breaking the pattern of the spin-off protagonists' ace monsters (though "Firewall Dragon" does resemble a Dragon and "Decode Talker" does resemble a Warrior, so they only break the pattern semantically).** It is also the first time a protagonist uses a newly created Type (in this case, [[CyberseSecurity Dragon]])".** This card eventually replacing the 2300 ATK "Decode Talker" as Yusaku's ace monster mirrors both Jaden Yuki's "An [[Elemental HERO NeosXyz Monster|Xyz]]", who eventually replaced the 2100 ATK counterpart: "[[Elemental HERO Flame Wingman]]", and Yusei Fudo's "Stardust Firewall eXceed Dragon", who eventually replaced the 2300 ATK "[[Junk Warrior]]".** Therefore the thematics of "Firewall Dragon" which, focus on recovery and Summoning back monsters to strengthen the field by its presence, can be similar to the effect of "Stardust Dragon" to protect the field from any harmful effect by its presence and Summoning itself back to strengthen the field.*** Those similarities are also applied to their rival monsters "3 [[Topologic Bomber DragonCard evolutions|upgraded]]" and forms: "[[Red Firewall Dragon ArchfiendDarkfluid]]", which are their complete foils and focus mainly to the destruction of the field to reign supreme by itself.*** This card also opposes "[[Borreload Firewall DragonDarkfluid - Neo Tempest Terahertz]]", as both monsters feature opposing stances and color schemes similar to "Stardust [[Firewall DragonSingularity]]" and "Red Dragon Archfiend." Furthermore, their effects also oppose each other, as "Firewall" willingly protects other monsters, while "Borreload" forcefully controls other monsters before sending them to the Graveyard.

VRAINS]]''s first artwork features a pose similar to anime, alongside "[[Decode Talker (anime)|Decode Talker]]".** This card has the same [[ATK]] (2500) as the signature cards of the other anime protagonists (with the artwork exception of [[Yuga Ohdo]]'s "[[Sevens Road Magician (anime)|Sevens Road Magician]]"): [[Yugi Muto]]'s "[[Dark Magician (anime)|Dark Magician]]", [[Jaden Yuki]]'s "[[Elemental Hero Neos (anime)|Elemental HERO Neos]]", [[Yusei Fudo]]'s "[[Stardust Dragon(anime)|Stardust Dragon]]", [[Yuma Tsukumo]]'s "[[Number 39: Utopia (anime)|Number 39: Utopia]]", [[Yuya Sakaki]]'s "[[Odd-Eyes Pendulum Dragon (anime)|Odd-Eyes Pendulum Dragon]]" and [[Yudias Velgear]]'s "[[Galactica Oblivion (anime)|Galactica Oblivion]]".** Although this monster was Yusaku's signature card, while its second artwork is it was used sparingly in the form anime: it "transitions" into was only Summoned five times before it became [[Forbidden]] in order to attackthe ''[[OCG]]''/''[[TCG]]''.

* This card is and "[[Decode Talker]]" are the first ace monsters of a spin-off anime protagonist to not be either [[Dragon]] or [[Warrior]].** Despite this, this monster cover card not to appear in has a dragon-like appearance and "Decode Talker" has a warrior-like appearance.** Both are also the first time ace monsters of a spin-off anime before the next booster pack cover card monsterprotagonist to have a new [[Type]], [[Cyberse]].

VRAINS|attack name]] in the ''Yu-Gi-Oh! VRAINS'' anime, "Tempest Terahertz" ("Tempest Attack"in the Japanese version), is likely named after based on Transient Electromagnetic Pulse Emanation Standard (TEMPEST) Attacksattacks, which work on the principle of intercepting electromagnetic radiation emissions from electronic devices such as monitors, hard disk and PC memory from a remote location, and allow the replay of the information captured.
