7 Decepticon Daishoguns
The commanders of the Decepticon Warrior Armies. Back when Bludgeon was still a human, the Daishoguns were his 7 loyal followers and after the end of the first great war, they intergrated themselves into mechanical transformer-like frames. Their designs are quite bizarre being modelled like Bludgeon himself. They have a regular head, but like Bludgeon this head is fake and their consciousness resides inside a synthetic true face somewhere on their bodies. They also wear a special "Invincible armoured gear", To represent their rank. Megastorm seems to be their de-facto commander. They also each lead their own unit of Decepticons and have their own mobile fortresses.

Regular Decepticon Enforcers
The Decepticons are split into 2 parts, those being normal Decepticons and "Kanjite Knights". Each of them are a part of one of the 7 units commanded by the Daishogun. These units include:
-Megas Corps: The largest of the 7 Decepticon units, being the main unit of all the Decepticon forces, commanded by Caesar. They are specialized for all various types of combat. Most of these turn into racing/civilian/labour vehicles or otherwise alt modes that can't easily be categorized into the other factions. Their mobile fortress is the Galvaburg II.
-Aeros Corps: The main aerial force of the Decepticons, led by Ramjet. Most of the members of this unit are winged and can fly, though some also use propellers instead. As such they turn into aerial combat vehicles. Their mobile fortress is the Belphaego.
-Spiritual Corps: Led by Black Zarak. Though this is the smallest of the 7 units, they are also the cruellest of them all, using fear and mental terror to their advantage. The members of this unit have a ghastly theme to them, being themed after various Cryptids. Their mobile fortress is the Bruxton.
-Yoroi Corps: The main ground force of the Decepticons, led by the vile Jallguar. This unit is much more fearsome than the rest when it comes to combat. Most of the members of the unit turn into ground military vehicles, and usage of explosive weapons seems to be a favourited tactic. Their mobile fortress is the Vantablack.
-Technos Corps: Led by Needlenose. This unit relies on strategizing and technology to gain an edge in battle. They mostly turn into construction vehicles, but some also transform into vehicles with tecnological equipment attached to them. Their mobile fortress is the Dodanpachi.
-Kerberos Corps: Led by Yokuryū. Thanks to being themed after reptiles, this unit is much more vicious than the rest. They turn into either reptiles or reptile-themed vehicles. Their mobile fortress is the Jet Dragoon.
-Aquarius Corps: The main aquatic force of the Decepticons, led by Rippersnapper. They excel most at marine combat, with the members having either marine vehicle or marine creature alt modes. Their mobile fortress is the Akula.
The Kanjite Knights are hand-picked from each of the 7 units and considered the strongest members of each of their units. Each of them are also given a epithet based on a letter of the alphabet and also their abilities. For instance, Barrage, having magnetics-based abilities, has the title of E - The Electromagnetic.
