"Fire Dragon" is the ace monster of the protagonist of the fifth film, Yusaku Fujiki, and the first monster to be listed as a forbidden card during the anime broadcast period. The appearance of this card has had an immeasurable impact on the real card environment, but considering its status as an ace monster, after being included in the banned card, K Society also quickly modified its effect text to make it comeback. This also leads to the fact that this card is an ace monster that has not yet appeared in the anime in the history of the game king.

This card is the current Arson Dragon effect, and the self-deprecating effect of "the effect of this card name can be used once per turn" has been added to the effect text before the modification. 2 The effect is changed from the original unconditional special summon monster to a special summon electronic monster.
The self-censorship effect of the Fire Dragon was changed because it involved the recycling of cards, and it was very easy to form a LOOP system that could operate in a perpetual cycle without a one-turn restriction. Later, some card guys used blood-cutting cards such as "Cannon Artillery" to build a blood-cutting FTK card deck with a fairly high achievement rate. This act directly led to the ban on the "Cannon Gunners" family on January 1, 2018, and the restriction of the "Fire Dragon".
The 2 effects of the Fire Dragon were changed to be limited to only special summoning of Electronic Monsters, due to the fact that the Deck guys used the LOOP system with its 1 effect, plus the effect of 2 effects to summon monsters from the hand cards, to build a deck that could gather the "Three Illusion Gods" in one turn and summon the "Creator god of light" to achieve regular victory. After the 2 effect was modified to be limited to the Electronics Monster, this construction naturally did not hold. However, this operation of the card guys made the fireproof dragon that was in danger in the eyes of the K Society even worse.
The construction that really allowed the "Fire Dragon" to enter the small black room was the emergence of the "Phantom Collapse Fist". Whether it is "Fire Dragon" with "Cannon Gunnery" or "Creation God of Light", it is an entertainment game with limited impact on the competitive environment, although for the K Society, touching FTK is a death sentence. However, the emergence of the "Fire Dragon Phantom Collapse Fist" is the strength embodiment of the "Fire Dragon" big brother. The Master Rules of the time stipulated that if a monster was to be summoned from an extra deck, the monster must be summoned in the LINK area. The high-intensity chain unfolding of the "Fire Dragon" with the "Phantom Collapse" monster can directly fill its own 5 monster areas and 2 LINK areas, so that the opponent can use without the LINK area, thus achieving the effect of additional sealing. At that time, there was even a "Fire Dragon Phantom Collapse Fist" to unfold the recipe: the double dragon stacked torture eagle, and the battleship laid eggs out of the liang dragon. Jump a spider to become a witch, and the witch will order eggs to give birth to hunters. The hunter adds an egg water dispenser to prevent the fire from collapsing all things.
In general, the "Fire Dragon" before the unmodified effect text can be said to be a real fake card. However, as the protagonist's ace monster, the K Society did not quickly ban it, but blocked the knife with the "Cannon Artillery". At that time, the animation was still playing, and K Society also needed to sell cards. "Fire Dragon" only appears 3 times in the anime, perhaps because the effect is too buggy, and rarely produces effects after appearance, and then it is replaced by the vest "Fire Dragon" and "Fire Dragon Dark Fluid".
In reality, "Fire Dragon" was banned on the TCG on December 3, 2018, banned on the OCG on January 1, 2019, and then released from the Small Black Room after the effect text was modified in the new table in January 2021. Although it has undergone the castration of the K Society, the lifting of the fire dragon restriction still makes the players cheer: the big brother is finally out of prison!
