Meka (not Mecha) cockpit background.
To be more specific, the cockpit of Akudama-meka featured in Zenderman.
Akudama-meka is the collective name for the giant mecha piloted by Muujo's trio, and is equipped with powerful weapons such as giant missiles, but they always suffer humiliating defeats due to the foolish actions of Muujo and her subordinates.
This background exists solely to depict Muujo being defeated in a mecha battle and caught up in an explosion, but be careful when using it in conjunction with the Muujo model as it tends to discolor her clothing.
