Candmon

Candmon (キャンドモン)
A Flame Digimon whose Digicore, which can also be said to be a Digimon's heart, burns intensely while mounted atop its head. When the Digicore on Candmon's head ceases to burn, it becomes unable to maintain its life processes. One theory suggests that the flame on its head is its true form, and that the rest of its body is naught but a dummy. Despite being a Flame Digimon, it has a docile personality and will not bring danger to its surroundings out of its own volition. Its Special Move is spitting out small fireballs (Bonfire).

Etymology
Cand: From candle (「キャンドル」 Kyandoru).
