Lucemon

While the name Lucemon refers to his Rookie form, Lucemon is unique in that his changes in mode also result in a difference in level.

Lucemon
Lucemon is a twelve-winged angel who has the body of a young blonde boy. He wears large yellow anklets and bracelets, and has the Digital Hazard sign imprinted on his left hand. He was an extremely powerful Holy Digimon, until he became frustrated with his ever-imperiled charges and then mad with power. Despite his fragile appearance, and the fact that he is only a Rookie Level Digimon, he is powerful enough that even Mega Level Digimon fear him. Awoken after a rebellion to bring about peace, it has been taught that he welcomed a long era of darkness. He was an Angel Digimon who believed others could not think for themselves and that the world would be a better place if he made all the decisions. Currently his abilities have been succeeded by the Celestial Digimon.

Lucemon's name comes from the Italian word for light "Luce", a reference to the fallen angel Lucifer.
