Dorumon (Seekers)

Dorumon is the partner Digimon of a Sons of Chaos member.

Digimon Seekers
When Eiji Nagasumi applies to join the Sons of Chaos he has to pass a test assigned by a member of the group to be allowed to join the group, and Dorumon's partner is chosen as the one to give Eiji his test.

The Sons of Chaos member waits for Eiji on top of a building in the whilst Mind Linked to Dorumon, who hides under a cloak to hide its identity. Eiji, Mind Linked within Loogamon, arrives two minutes late which causes the member to dock him two points on the mission. Eiji suddenly appears next to Loogamon, which surprises even Loogamon. Eiji explains he had remembered he was told he could access commands on virtual monitors by thinking of doing it and having seen a button saying hololize simply thought of pressing it which allowed him to hololize next to Loogamon. The SoC member was also surprised and tells Eiji that his mission is to create a map of Ninth Avenue for them, and that he just has to walk around the area with the provided map tool as it would auto fill the information for him. Loogamon laughs, and informs Eiji that the mission was perfect as it had something it needed to do in Ninth Avenue anyway. The Sons of Chaos member wishes Eiji luck on his mission, hoping he would be able to pass and become a member of the group.

As they watch Eiji and Loogamon leave, Dorumon tells its partner it was surprised Eiji was also Mind Linking to which the SoC member expresses surprise at not just that but the fact that Eiji had already shown up with his limits unlocked. It wonders if Loogamon had noticed they were also using Mind Link then asks why its partner had given the Demon Wolf of the Castle of Nine Wolves such an easy mission. The SoC member realizes Dorumon was right and contacts the DigiPolice, telling there where Eiji was.

When Eiji and Loogamon arrive at the Castle of Nine Wolves they are intercepted by the DigiPolice who ask to talk to him on GriMM. Turning down the request would be seen as going against the DigiPolice but Eiji had no choice in the matter as his means of communication during the mission was in the hands of the Sons of Chaos member running the mission who proceeds to turn down the request.

Dorumon and its partner, still Mind Linked, watch in awe as Eiji and defeat the DigiPolice. After the two of them leave, Dorumon chastises its partner for telling the DigiPolice about Eiji, though he just muses that he was right about how powerful Loogamon was. He notices that Eiji had completed the mission having sent him the map data, and decides to accept him as an official member of the Sons of Chaos in the hopes that Eiji will be able to lead Loogamon into become an even more powerful Digimon. The wind then blows off Dorumon's cloak.
