Fan:Lilithmon (Digi-Rangers)

Lilithmon is the most evil Digimon known, but she was once a friendly Digimon and best friend of Patamon. When she failed the exam given by Baihumon, she left and began training by Daemon, and became evil. She Digivolves all the way to Mega; Lilithmon.

Lilithmon wanted to kill both Seraphimon, and Baihumon. Baihumon died due to old age, and she raged war with Seraphimon, in the end both lost.

Lilithmon finally re-emerged 20,000,000,000 years later and planned to destroy Earth, knowing the legend of the DigiDestined and the Tamers. But she never knew Seraphimon's plan with the Digi-Rangers, and she meets one failure, after another.

Lilithmon tries to destroy the Digi-Rangers with the last DigiMemory, and used a evil Digi-Ranger, but that plan failed as well and the new Ranger goes to the good side.
