Rosemon

Rosemon
Rosemon is a Fairy Digimon whose name and design are derived from the rose. She is known as the "Queen of Flowers", and wears the Tifaret Jewel, the symbol of love and beauty, which prevents her from aging. She is the Mega form of both Palmon and Lalamon. She is quite an over conscious Digimon, and although she won't accept defeat from other mega levels, she is the fencing queen whose rose sword will bloom with crimson energy in the battle field. Moreover, she holds the Tifaret Jewel which she can use to unleash the ultimate temptation and the vine on her left arm can be used to enslave any monster she chooses.

She seems to resemble Cutie Honey, a transforming girl from another anime.
