Dragonburn debuted in Hunted, where it and Dom Pyro almost hunted and captured the entire Core-Tech Team, until Chase and Lock defeated them at the Center Temple, by collapsing the roof.
In Trophies, its Core was found by Dom under the fallen debris and Dragonburn was spun out once again. Later, Dragonburn was spun out against Lock, Quickforce, Charger, and Bioblaze, but it was quickly called back into its Core and Dom handled the Core-Tech Monsuno himself. Dragonburn then fought against Lock and Quickforce and was almost turned into a trophy, but Dragonburn's energy ran out and it returned to its Core.
In Pentoculus, Dom Pyro ordered Dragonburn to hold Beyal down as Klipse's Monsuno serum was filling the whole cave. Lock shoved Dragonburn off of Beyal and onto the serum. Once Dragonburn made contact with the serum it disintegrated, ending its existence and leaving Dom Pyro in anguish.
