Four Great Dragons

The are a group of four Ultimate-level Dragon Digimon that is composed by Qinglongmon, Goddramon, Holydramon and Megidramon. These Dragon Digimon posses such immense power that they came to be known as the Four Great Dragons, but they don't work as a team. They can never be ignored by Digimon of the same ilk, as they will set trials for the other Dragon Digimon.Digimon Profile: The Four Great Dragons It is said that Slayerdramon's form is one that can only be attained by those who complete the training that is called the "Trial of the Four Great Dragons", which can only be challenged by Dragon Digimon.
It's considered that Qinglongmon is the most deified existence in the group, while Goddramon has the strongest magical power among the four. On the other hand, Megidramon has a personality so fiendish that it doesn't bear the slightest resemblance to the other three. It boasts the fiercest, most evil destructive power among the Four Great Dragons.

One day, Megidramon lost control causing all kinds of destruction. However, Qinglongmon, Holydramon and Goddramon intervened by attacking their companion, causing him to regress to Guilmon.
Despite Goddramon's arguments to eliminate Guilmon, fearing that he would become Megidramon again, Qinglongmon and Holydramon chose to leave him alive, in the hope that living with other Digimon would change his heart. However, Goddramon continued to watch him from afar, ensuring that he would eliminate him if Megidramon lost control once again.
After several unfortunate events, Guilmon, who lost his memories, once again became Megidramon, after seeing his friend Sagittarimon being hurt. Goddramon appeared and started a new fight, but Megidramon remained motionless, saying that he wanted to use his power to protect the weakest.
Back in Guilmon's form, Goddramon instructed him to take a journey around the world helping the weakest. This journey would lead Guilmon to become a Holy Knight in the future.

At some point after the great war where Yggdrasill and most of the Royal Knights disappeared, Homeros sent Marsmon, Ceresmon, Dianamon and Venusmon, from the Olympos XII, to the Digital World of Yggdrasill.
Originally sent to investigate whether the other world would be able to prevent its own collapse, the group was to contact the Royal Knights and confront them if necessary.
Goddramon, one of the Four Great Dragons, intervenes and takes advantage of the quartet's lack of prior knowledge of the Royal Knights and attempts to trick them with the help of Megidramon, who took the form of Chaos Dukemon to pose as the Dukemon Royal Knight. After the hoax is discovered, the other members of the Four Great Dragons emerge and begin a debate with the Olympos, who after discovering the absence of Yggdrasill and his knights, worry that with the absence of God the Digital World could collapse. 
After the battle between Goddramon and Marsmon (where Goddramon evolved into Goddramon (X-Antibody) after releasing all his sacred power), Dianamon and the others decide to return to Iliad, where she herself will inform Homeros about the situation, although she cannot guarantee that he will not send the other members of Olympos XII. Goddramon X then asks Homeros to be informed that if he wants to dominate his world, they will be enemies next time.
Some time later... Qinglongmon is informed by Andiramon about a portal, although the Four Great Dragons debate whether it is an invasion from Iliad or not, they cannot even figure out if it was actually a portal or just a Time Rift, since Zhuqiaomon plunged everything into flames, as it was in its territory.
After some more time, Mihiramon informs Qinglongmon that a new portal has appeared. Although Megidramon wishes to fight the invaders, since Goddramon (X-Antibody) took the spotlight earlier, he is scolded by the other members about being too much for just four Digimon, with Qinglongmon revealing that the other Four Holy Beasts will also join the battle. At this moment, Makuramon appears, and despite Megidramon's complaints about him not speaking clearly, the Deva reveals that Baihumon has already come into direct confrontation with the invaders.
Arriving at the location, the group sees Baihumon facing Jupitermon and Junomon, who states that this world will eventually be taken over by Homeros. Entrusting the fight to the tiger, Qinglongmon is informed by Andiramon and Majiramon that Zhuqiaomon and Xuanwumon have found Dianamon and Ceresmon, and that there are also two more Digimon with them, in addition, a powerful aquatic Digimon has appeared in the sea, and Ancient Mermaimon is gathering an army to face him. 
After Qinglongmon follows Sinduramon to investigate a Digimon that is poisoning everyone, Goddramon X decides to go in search of Marsmon, and Holydramon goes to Baihumon's aid, leaving Megidramon to find the remaining invaders, and warning him to be careful with Venusmon.
Following the path indicated by an Armadimon and a Phascomon, Megidramon finds Venusmon accompanied by Vulcanusmon, although Megidramon is ready to fight, the confrontation ends up becoming just a debate due to Venusmon's kind nature, which reveals that Jupitermon has already defeated two of the allies of the dragon and that the seas already belong to Neptunemon. Vulcanusmon, worried about Venusmon, eventually steps in front of an attack that Megidramon launches after becoming tired of the two and leaving to investigate the truth, while Venusmon heals his partner's wounds.
After overhearing a conversation between a Calamaramon and Neptunemon, Megidramon realizes that all of Olympos XII is here, so Iliad is unprotected, the dragon then decides to invade Iliad to destroy Homeros alone. Before leaving, Megidramon asks Holydramon to destroy the portal if he doesn't return.
After Megidramon crosses the portal, Jupitermon receives a message from his god about the invasion, sending Apollomon and Dianamon to take care of the situation. Although the pair return to Iliad in time, they are unable to face him, as Dianamon is still injured by Zhuqiaomon's flames, and Apollomon's flames are useless against the dragon.
At this moment they both hear Homeros' voice, calling them "My Knights", the god grants them the power to evolve even further, leading to the appearance of Grace Novamon, which Megidramon responds by releasing all his power, evolving into Megidramon (X-Antibody) and going crazy in the process. The other Olympos return and together they create an opening for Grace Novamon to attack.
While in the Digital World of Yggdrasill, the remaining members of the Four Great Dragons prepare to destroy the portal. Despite Holydramon's objections to them believing in Megidramon, Goddramon X begins to say that after this they will have to choose a new member for the group. At this moment Megidramon's voice can be heard questioning why a new member, with the dragon returning in its original form.
Holydramon asks what the result of the battle was, however, Megidramon doesn't remember anything after releasing his power, but believes that since he is there, he must have won. At that moment Qinglongmon and Goddramon X notice an seal from another world on Megidramon's body, which Qinglongmon says could be the answer they were looking for.
Ignoring Megidramon's questions, Qinglongmon says that they must go now, as the Digital World needs them to begin its reconstruction after the war.
