Candlemon

Candlemon is a Rookie Level Flame Digimon. His Japanese name is Candmon. His name comes from candle, which is what he resembles. The fire on him is his Digi-Core, which, if it goes out, kills Candlemon (compare with the Charmander line in Pokémon). Being a flame-type, he has a quiet personality and doesn't battle to make progress. Interestingly, the flame on his head resembles DemiMeramon, a Digimon he digivolves from.

Digimon Frontier
Takuya Kanbara, Zoe Orimoto, J.P. Shibayama, Tommy Himi, Neemon and Bokomon stumbled upon some ruins in a gorge guarded by a village of Candlemon. When they said they were Legendary Warriors, they invited them to their party and burned what turned out to be Sleeping Clovers. The kids ran from the Candlemon (during their escape they also hid in a river), until Takuya became Agunimon, yet was no match for them, since his fire-based powers only strengthened them. However Tommy then found his Human Spirit of Ice, became Kumamon and defeated some Candlemon until one of them Digivolved to a Wizardmon. Agunimon and Kumamon defeated Wizardmon and reverted him to Candlemon, by scanning his Fractal Code. The Candlemon Elder said it was a test and Wizardmon's Fractal Code restored the bridge. Multiple Candlemon were later seen at the Autumn Leaf Fair.
