|This article is about a/an Mirror Monster in Kamen Rider Ryuki.|
- ―Announcement from the Dragvisor after inserting the Advent Card.[src]
Dragreder initially appeared in Episode 1 and was originally a rampant Mirror Monster that was targeting Shinji. However, Shinji was eventually able to form a contract with it, becoming Kamen Rider Ryuki. Dragreder did not play a very important part in the plot for most of the series and mostly only appeared for Ryuki's Strike Vents and Final Vents or when eating a monster's life force. Despite its role as the main monster of the series, Dragreder acts like any other Mirror Monster: it will listen to Shinji when given definite commands but will go after him should it run low on life energy. One major difference is that it will sometimes come to Shinji's aid without the need to summon it with an Advent Card.
With the acquirement of the Survive Rekka Advent Card, Ryuki was able to change into Survive Form and hence, Dragreder was able to evolve into a much more powerful form named Dragranzer. With this evolution, Dragranzer was also able to transform into a motorcycle that Ryuki would use to complete his Final Vent. Later on, during the end of the war, Dragreder seems to have learned to respect and care for Shinji.
It is unknown what happened to Dragreder after Shinji's death as it did not become rampant. But because Shiro eventually altered time so that the Mirror World never existed, it can be assumed the same for Dragreder. However, recent developments revealed that Dragreder was somehow revived and under the command of Shinji once more without a proper explanation as to how this happened.
Dragreder still supports Ryuki in all of his fights and as part of his Final Vent. A significant battle it took part in though was the final battle between Ryuki and his evil mirror image, Kamen Rider Ryuga. Instead of being summoned, Dragreder came of his own volition, defending Shinji when Ryuga summoned Dragblacker. After helping Shinji finish off both Ryuga and Dragblacker, it evolves into Dragranzer when Shinji assumes Survive Form to take on the Hydragoon horde plaguing the city.
Dragreder is the contract monster of this world's Kamen Rider Ryuki, Shinji Tatsumi, for his participation in the Rider Trials. It never had a chance to appear in the series tribute episodes, and when Shinji used Time Vent, he used too much of its energy, thus Ryuki's Visor can only use a few weak Advent Cards.
To compensate for this, Dragreder became Ryuki's Final Form Ride, allowing Kamen Rider Ryuki to transform into a smaller version of Dragreder.
World of Rider War
Dragreder was among the contract monsters that fought Kamen Rider Decade along with their contract holders. It, along with Dragblacker, attacked Decade head on, but were shot down before they could even reach him.
All Rider Break
Super Hero Taisen
Kamen Rider Decade used an Attack Ride Card which summons Dragreder when he is in his Ryuki Form. In response, Captain Marvelous as GekiRed utilized "Geki Waza! Gun-Gun Bullet!" (激技! 砲砲弾! Geki Waza! Hō Hō Dan!), summoning a manifestation of GekiTiger. They were evenly matched.
Later, in the last stages of the battle with the Shocker-Zangyack Alliance, Dragreder was summoned by Ryuki himself for the Dragon Rider Kick. This, combined with Kamen Rider Blade's Lightning Blast and Decade's Dimensional Kick, was able to defeat Doktor G, revealing him to be Narutaki in disguise.
World within the Magic Stone
During the 14 Heisei Kamen Riders' battle against Amadum's monsters in the World within the Magic Stone, when various giant and flying monsters appeared, Ryuki noted that they could handle big enemies too. He proceeded to board Dragreder, fighting alongside the other Riders pulling off their various tricks and destroying several Hydragoons.

Super Hero Taisen GP
In the History Modifying Machine's altered history, "Shocker Rider Ryuki" summoned Dragreder while attacking Kamen Rider Drive. Though Ryuki was later erased by the Rider Robo, he and Dragreder's place in history would be restored once the Machine was destroyed by Shurikenjin Tridoron.
Kamen Rider Zi-O
As a result of the Ryuki Ridewatch, Dragreder served Ohma Zi-O in the dystopian future of year 2068. During Zi-O and Tsukuyomi's arrival to the future, Dragreder was summoned to intercept Zi-O when he attempted to attack using Ryuki's power in RideHeisaber.
Dragreder was originally an above-average Mirror Monster that went after Shinji, constantly stalking him and trying to find a chance to devour him. When Shinji formed a contract with him, however, Dragreder looked upon him with a strange aura of analysis, suggesting that he was wondering whether Shinji was truly worthy of forming a Contract with him.
Over the course of the war, Dragreder would sometimes be annoyed with Shinji when he stops him from feeding on Mirror Monster energy, and was especially annoyed when Shinji's horror at supposedly taking Gorou's life caused him to stop fighting. This caused Dragreder to try eating Shinji, but was stopped by Yui.
By the end of the war though, it seems some of Shinji's personality has rubbed off on Dragreder, who sometimes comes to his aid without being summoned through Advent and responding to emotions of distress and anger.
Dragreder appears as Ryuki's Contract Monster summoned by Advent Card with its AP value at 5000. It resembles a mechanical Japanese dragon. When it first appeared, it acted hostile towards Shinji until he used the Contract Card, making Dragreder loyal towards Shinji. Like all Contract Monsters, whenever Shinji walked at a mirror or any other reflective places, Dragreder will always be seen tailing him as it is a humble servant to Ryuki.
Its known body parts include the Drag Tail (ドラグテイル Doragu Teiru), its blade-like tail, and the Drag Body (ドラグボディー Doragu Bodī), its armored abdomen. Its mouth, named the Drag Jaw (ドラグジョー Doragu Jō), enables it to perform the Drag Breath (ドラグブレス Doragu Buresu) attack, a fireball with a temperature of 5,000°C (9,032°F).

Once Ryuki uses a Survive Card, Dragreder evolves into Wildfire Dragon Dragranzer (烈火龍 ドラグランザー Rekka Ryū Doraguranzā) and gains a new range of card abilities as well as generally becoming more powerful, with its AP upgraded to 7000. Its favorite attack, the Drag Breath (ドラグブレス Doragu Buresu), was upgraded now able to spit stronger fireballs with the temperature of 7000°C (12,632°F).

After Ryuki Survive used the Final Vent Card, Dragranzer's Drag Eye ( ドラグアイ Doragu Ai) is covered with Drag Face Shield (ドラグフェイスシールド Doragu Feisu Shīrudo), followed by the development of Drag Wheel (ドラグホイール Doragu Hoīru) on his chest which later covered with Drag Arm (ドラグアーム Doragu Āmu) and finally his body folded into a "Z" shape that forms a motorbike with Ryuki Survive riding it. In this form, Dragranzer is a Honda X4 bike with a dragon motif. However, there are such cases where Ryuki Survive rode Dragranzer Bike Mode without the Final Vent Card's activation.

- Final Vent: Initiates the Dragon Fire Storm (ドラゴンファイヤーストーム Doragon Faiyā Sutōmu) attack where Dragranzer transforms into a motorbike with Ryuki Survive riding it, then rises onto its rear wheel with the tail extended for balance, then Dragranzer spits the Drag Breath attack in the form of fireballs, then blasts through any opposition by slamming into them.
Through the use of certain Advent Cards, parts of Dragreder's body can be used by Ryuki as weapons or other equipment.
