A synthetic Digimon created by Ken Ichijouji.
Chimeramon is a creation of Ken Ichijouji during his time as the Digimon Emperor. It was his project to make a loyal and superior partner to Wormmon. It body parts were from many of the chosen children Digimon and a few of his Digimon controlled by the Evil Ring (Dark Ring). After adding Devimon's arms to Chimeramon his creation was complete and he sent it after the Chosen Children. Proving to be stronger than their armor leveled Digimon the Chosen Children were able to escape from their first encounter with Chimeramon. However, because of the dark powers of Devimon, Chimeramon started to become rebellious to it's masters control and starts running amok while destroying everything in its path. After Daisuke obtained the Digimental of Miracles and used it to Armor Evolve Veemon into Magnamon Chimeramon sensed it's power of light and immediately went after Magnamon. After a lengthy battle Magnamon was losing energy and Chimeramon gained the upper hand until Wormmon gave Magnamon his energy to finally defeat Chimeramon once and for all with his Extreme Jihad attack. However being defeated Chimeramon was able to survive by fusing his remaining energy with the Dark Master Mugendramon (Machindramon) becoming Millenniummon.
