Negamon

An In-Training Digimon that grew by immersing itself in the negative data overflowing from the network. Negamon always wishes for its own demise, and lives quietly within jet-black darkness. It appears before Digimon who get close, using Downer Eye to cause them to prey on themselves under a curse. Said Digimon gradually lose their emotions, fall into darkness, and erode from the inside out, becoming seedbeds to generate new Negamon.
