The Mechagodzilla (メカゴジラ Mekagojira?) of the AniGoji continuity was the fourth Mechagodzilla in the Godzilla film series, and the first and only Mechagodzilla in the Reiwa era of films. This Mechagodzilla made its first appearance in the novel, Godzilla: Monster Apocalypse, a prequel novelization to the 2017 film, Godzilla: Planet of the Monsters, which detailed its origins and original fate. Mechagodzilla then appeared in the 2018 prequel novel, Godzilla: Project Mechagodzilla, where more of its history and abilities were run down. It made a cameo appearance in Godzilla: Planet of the Monsters and its manga adaptation, where its failed use was briefly detailed. Mechagodzilla went on to have its first major film role in the 2018 film, Godzilla: City on the Edge of Battle, where it was used once more against Godzilla, and was eventually destroyed.
