The Plan-1055 Belial is one of the worlds first 4th-generation Arm Slaves. It is Leonard's personal AS, and he uses it to destroy the ARX-7 Arbalest. Its only known weapons are its claws and a bow.
There isn't much information regarding Belial development, it is known to be designed by Leonard Testarrossa himself, based on the chassis of the ZY-98 from the USSR.
Belial is the first 4th generation AS in the world, and possess a rather stable, functional, and powerful Lambda Drive. Its most interesting feature is its flight capability due to the Lambda Drive, followed by its special Bow that delivered near instant massive damage via the Lambda Drive.
The Suit is remarkable for its balance regarding offensive capabilities at close and medium range, along with considerable defensive capabilities, Lambda Drive and astonishing mobility, its main drawbacks is its over reliance on the Lambda Drive.
The first operational mission that we are aware is the kidnapping of Kaname Chidori in Tokyo. While Amalgam forces where costly defeated, the Belial arrives as the last opponent and easily destroys the ARX-7, only using its claws.
After we have the deployment in the URSS and the subsequent mission in Yamsk-11, at the end of said engagement Belial faces the 2nd 4th generation AS produced the ARX-8, the fight is a balanced one, and the deployment of the Fairy's Feather nulifies some of the offensive and mobility capabilities of the machine, the struggle is interrupted with the arrival of Soviet Forces in the area.
The last engagement of the Belial is a duel against the ARX-8 in the 2nd Battle of Merida Island. The unit, after a tough fight, is completely destroyed.
