Uninterested in attaching themselves to humans, Gazimon enjoy setting traps for other Digimon and watching them fall into them so they can bully, tease and threaten weaker Digimon.
The Gazimon were the servants of Etemon who loved his awful singing and operated his Dark Network and other grunt work. One seemed to have a pair of sunglasses like his. When Etemon was supposedly killed after the fight with MetalGreymon, that Gazimon and another one plotted revenge against the DigiDestined but decided not to, since they had never liked Etemon. The two ate the mushrooms of forgetfulness.
During Wizardmon's flashback of how he met Gatomon, Three Gazimon passed Wizardmon when he was close to death but they never stopped to help him and continued their track.
