A fanlisting is like an internet clique people join to show they are a fan of a subject. Ken, at first, hated Wormmon. He didn't think he was 'cool' enough for an evil kaizer like himself to have, and much preferred Agumon's later forms such as Metalgreymon. Wormmon, despite his rough treatment, knew there was another side to Ken, and later sacrificed himself to prove it. After the incident, when Ken was given another chance with Wormmon, the two became inseperable.
