Slog

A member of the Monstructor Six, Slog was part of the first know combiner ever know in history(unless you consider Nexus prime one) but was sealed away by the Autobots until he was freed with the rest of his teammates by the Decepticons.

Slog is an artist and a sculptor, but his art is disturbing. Calling it the Slogism movement he makes paintings and sculptures about the gruel of war, all the dead. Almost all bots are freaked out by this.

He can combine with his teammates to form Monstructor.

History:

Slog was born some time before the Malignus-Guardian war and stayed neutral with a grope of friends, During the war they found the Matrix of Combination and him and his grope accidently became Monstructor.

As Monstructor he lived in the sea of rust and was eventually captured and locked away by the new Autobots, They were freed by the Decepticons during sentinel times and they joined the Decepticons out of gratitude.

He helped train the other combiners as Monstructor, and during the ensuring battle against the Autobots attacked Victorion along with Devastator, Liokaiser, Abominus and Dinoking before being swatted away by Volcanicus[Operation: Combination]

He was at Spinsters funeral after the Decepticon died at the hands of fracture in battle and comforted flywheels.[Threat of Megaempress]he was on Floron 2 when space knights were on it and combined Into Monstructor[confusion on Floron 2] 

Notes:

He's based on the G1 Decepticon of the same name

He shares his Bodytype with Grimaster
