Draconir

His full name is "Draconir, Knuckle Dragon". Unlike other Digital Friends, he is able to talk, a feat that even himself is oblivious about its cause since his memory data was separated from him by the Arc Ruler.

Light Tenryu receives his card inside the deck that Wolfram Zerga gives him. Upon installing the deck on his smartphone, Draconir emerges surprising Subaru and Itsuki by being able to speak.

Draconir supports Light during his battles, being able to talk with him whenever he draws his card.

After discovering that Draconir's memory is stored in different data devices that the Seven Shadows possess, Draconir and Light set out to get them to discover the secret behind Draconir's origin. They got the first piece thanks to Subaru's battle with Kaguya, which reveals that Draconir was somehow related to the Arc Ruler. The second piece, given to them by Hiro Ryūgasaki, showed that the Arc Ruler made some kind of modification in Draconir.

His evolved legendary form is Draconir, Burning Dragon; achieved during Light's battle against Arc Ruler.

He later evolved even further as a True Arms follower, Draconir, Burning Dragon Evolflame; achieved during Light's second battle against the Nexus-enhanced Wolfram Zerga.

Draconir is energetic and passionate. He is very loyal to Light and cares a lot for him.
