This is an Illustrious style lora for Mechagodzilla from the Showa period of the Godzilla movies in 1974 and later in a second movie in 1975.
This first version of Mechagodzilla was created by a group of aliens called Black Hole Planet 3 Alien, due to coming from the third planet orbiting a black hole. These aliens also used other monsters like Frankenghidorah, Titanosaurus, All-Terraintula, and Jet Jaguar before the robot became self aware and a hero. A fun fact is that the suit used for the Showa Mechagodzilla is the oldest suit still in good condition, and is on display in museum like conditions.
A weight of 1 to 1.5 works well with this with most models. Sampling Steps of 15 to 35 works well with most models, as does a CFG Scale of 5 to 7.
Prompts for this lora are ( ShoMeGo, muscular, robot, Mechagodzilla, ).
