[Gallantmon, Ultimate, Virus, Holy Knight-type Digimon. A Holy Knight-type Digimon known as one of the "Royal Knights" alongside Omnimon and Magnamon. The "Royal Knights" are Digimon at the highest level of network security, and breaching security in their presence is absolutely impossible. Despite being a Virus attribute Digimon, Gallantmon is also a guardian deity of the network, highlighting a contradictory existence that could become dangerous should that balance be lost. It is said that Gallantmon is a Holy Knight-type Digimon born from immense destruction and has an unclear relationship with a certain Demon Dragon. Clad in holy armor exquisitely crafted from 99.9% pure "Chrono Digi-Alloy," Gallantmon wields the holy lance "Gram" in the right hand and the holy shield "Aegis" in the left. Gallantmon values chivalry and is loyal and righteous toward a liege. Gallantmon's special moves are "Royal Saber," a powerful strike delivered with the holy lance "Gram," and "Paradise Lost," a beam that purifies everything, released from the holy shield "Aegis" on the left arm.]
After the golden light faded, a Holy Knight-type Digimon appeared before Mo Yan's eyes, clad in form-fitting knightly armor with the "Digital Hazard" symbol emblazoned on the chest and a red cape billowing behind.

A holy knight of the Royal Knights has completed their evolution chain.
Presumably, Yggdrasill's involvement was the reason the Wicked Demon Dragon was willing to offer up some of his core data back then.
Otherwise, Qinglongmon's standing as one of the "Four Great Dragons" and Authority Power alone, or the temptation of freedom from captivity, would not have been enough to persuade the Wicked Demon Dragon to offer up some of his core data.
If Yggdrasill was involved, that would make much more sense.
