Azulongmon

Azulongmon is an Exalted Dragon Digimon, one of the four Digimon Sovereigns and the Guardian of the Digital World's Eastern Hemisphere. He is also one of the Four Great Dragons (alongside of Goldramon, Magnadramon and Megidramon). His Japanese name is Qinglongmon, derived from Qinglong, the Chinese astronomical name for the eastern quadrant of the sky. The Japanese word Seiryuu is also derived from this. He commands the Devas Mihiramon, Majiramon and Antylamon.

Azulongmon appears only in times of critical importance and favors the human/Digimon bond though he rarely helps them and others unless needed to.

Azulongmon is the second highest Sovereign, lso the second oldest he is almost as powerful as the creator Fanglongmon.

Digimon Adventure 02
Each Digidestined's Crest was used to free each of the Guardians (Sovereigns are known as Guardians in 02), it seems that it took two Crests to free one Guardian, and as Azulongmon stated while talking to BlackWarGreymon and the 02 Digidestined, was released by the Crests of Hope and Light.

Digimon Tamers
Azulongmon first appeared when Zhuqiaomon attacked the Tamers. He saved the humans and their partner Digimon and then shortly fought against Zhuqiaomon. He finally convinced Zhuqiaomon to not attack the Tamers so that they could focus on the true enemy, the D-Reaper. He told the Tamers the history of the Digital World and each of its layers. He and Zhuqiaomon later met with Baihumon and Ebonwumon to discuss the D-Reaper situation and helped to release Calumon's Shining Digivolution power which Digivolved every Digimon to their Mega forms. In the final battle against the D-Reaper, Azulongmon assisted Zhuqiaomon, Ebonwumon, and Baihumon into dragging the D-Reaper back into the Digital World during Operation: Doodlebug, thus saving the Tamers. Azulongmon has a noticeably different personality in Digimon Tamers then in Digimon Adventure 02. In Adventure 02 he's depicted as extremely witty, while Tamers he's depicted as serious and no-nonsense.
