One of the Ten Legendary Warriors that saved the Ancient Digital World, possessing the attribute of Thunder. A Mega that existed in the far-distant past, AncientBeetlemon’s appearance is akin to the fusion of many insects, such as rhinoceros beetles and stag beetles. Its sturdy carapace rivals the strength of Chrome Digizoid, the sickles on both arms cut through anything, and it possesses enough power to easily lift objects hundreds of times heavier than itself. The abilities of AncientBeetlemon would later be inherited by Insectoid Digimon and others. Its special move Calamity Thunder rains down lightning that heralds incredible disasters, and Tera Blaster is a super-electrical discharge a thousand times stronger than Tera Blaster.
