Meramon

Meramon is a Flame Digimon whose name and design are derived from the onomatopoeia for burning (めらめら). It is shrouded with crimson flames over its whole body. As a Digimon that was generated from the defensive "Firewall" that protects things like the Internet from illegal entries, it possesses a violent temperament like the flames that wrap its body, and tries to incinerate everything it touches. It has stronger fire power than the same species on File Island, and taming this Digimon is very difficult, and as a result, even if it's tamed you won't know when it will bare its fangs.
