Meramon

Meramon is a Flame Digimon that is made of fire and can perform fire attacks. His name comes from "meramera", a Japanese word to describe the fierceness of fire.

Meramon was born from the defense wall "Firewall" for the purpose of protecting the internet from Digimon who enter it illegally. He is rarely violent, and it seems the flames that engulf his body generally seem to scorch him. It is very hard to control him, and even if you do, you will never know when he might turn against you. Meramon's body is capable of burning anything that touches it. Meramon can survive in lava.

Digimon Adventure
The first Meramon seen resided in Mount Mihirashi, a mountain where the water for the Yokomon Village came from. He was the first victim of the Black Gear. When he rampaged the Yokomon Village, the water dried up before his arrival. He was freed from its control by Birdramon and returned to the mountain. A different Meramon was a customer at Vegiemon and Digitamamon's diner. The same Meramon from before later returned during the final battle against the Dark Masters. Another Meramon was briefly seen on the TV when Tai came back to the real world after defeating Etemon.

Digimon Adventure 02
Some Meramon were under the control of the Digimon Emperor's Dark Rings in a fire pit location where a Control Spire was. They gave the DigiDestined a difficult time since attacks from Flamedramon, Halsemon, Digmon, and Pegasusmon couldn't damage them. When the Digimon Emperor and his flock of Airdramon arrived with Greymon under his control, he wanted it to Digivolve to MetalGreymon. Instead it Digivolved to SkullGreymon and took out the Meramon, Flamedramon, Halsemon, Digmon and the Control Spire.

Another Meramon was a partner to a DigiDestined named Mina from India. That same Meramon was among the many Digimon seen during the final battle against MaloMyotismon.

Digimon Tamers
A Meramon was the first Digimon that the Tamers encountered upon their arrival in the Digital World. It attacked them, thinking that they were enemies until Leomon attacked him and Meramon apologised. He told the Tamers how he wished he could go to the Real World. Later that night, a group of Jagamon stampeded and the Tamers barely escaped but Meramon was not lucky as the Jagamon trampled him and he was destroyed. In the morning, the Tamers made a marker to remember him by and the Jagamon that settled to sleep nearby had some explaining to do.

After Gaogamon defeated most of the DemiMeramon, the three remaining ones combined together to form a large Meramon. He was defeated by GeoGreymon and returned to the Digital World as a Digi-Egg.

Digimon Next
A Meramon was responsible for burning the grasslands where Sunflowmon's group used to live. He appeared at the Oasis to destroy it and his fires trapped Sunflowmon's group and Tsurugi Tatsuno's group in the water. He has DemiMeramon as his underlings. Agumon Digivolved to GeoGreymon and his attacks had no effect on Meramon. Gaomon Digivolves into Gaogamon and knocks it into a fountain of water where a Black Digi-Core is discovered. When removed from Meramon by GeoGreymon, Meramon returned to normal. It was revealed that Barbamon placed the Black Digi-Core in Meramon to control him.
