The Megalon (メガロ,   Megaro?) of the AniGoji continuity is a giant beetle-like kaiju created by Toho that first appeared in Godzilla: Monster Apocalypse, before returning in the sequel novel, Godzilla: Project Mechagodzilla.


Although Megalon's appearances in history were lower key in nature, the total damage it caused to humanity was severe.

Godzilla: Monster Apocalypse

All its known activities were focused on the African continent.

In 2012, Megalon initially appeared on the west coast and began crossing the continent to the east, annihilating countless smaller and developing nations before disappearing into either the Indian ocean or the Mozambique Channel. While the total length and aspects of the initial attacks were unclear, catastrophic damages on humanity were reported, with 20 million casualties, including the wounded, and mass numbers of refugees caused by this disaster.

Many rulers of dictatorship nations abandoned their citizens and fled, resulted in the loss of public peace and order. Many of the refugees headed to North Africa or Arabian regions due to frequent occurrences of morasses of civil wars in their own regions. The total count of refugees reaching Egypt surpassed one million by 2015, resulting in shortages of food supplies and triggering a second civil war. Furthermore, a pack of Griffons attacked Cairo in 2021.

Megalon made its second appearance ten years later; it attacked the Republic of South Africa and brought on the total destruction of the nation in 2022. Even though South Africa was economically powerful, and relatively safe until this event.

The total population of the African continent was halved only 10 years after Megalon's first appearance, and humanity was forced to abandon the continent.

Godzilla: Project Mechagodzilla

In 2029, Megalon attacked and annihilated Pakistan and India during the nation's restoration efforts. Following this, the incident was officially reported as a nuclear war but also implied to be anti-kaiju operations.

Later, it moved northward after rampaging in the Philippines, breaching the defense line formed by the United States and Japan and reaching the Ryukyu Archipelago.

When it came ashore at Blue Beach, King Caesar emerged from Manzamou and battled Megalon. Although the battle ended in the deaths of both monsters, the damage on Okimawa was not severe thanks to King Caesar. This incident inspired humanity the idea of 'LTF, the Let Them Fight strategy.


  • Mari Kaera, one of featured characters, was a refugee due to attacks by Megalon, and later lost her parents in İzmir due to Orga's attack.
  • The total casualties caused by Megalon's arrival and rampage is possibly second after Godzilla's record, and along with Dagahra, Megalon is one of the few monsters other than Godzilla to force humanity to abandon a continent.
  • The scenario of the battle between King Caesar and Megalon resembles the of the two in the Godzilla: Rulers of Earth series.
