Scowl

A member of the Monstructor Six, Scowl 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.

Scowl is a physical brute, he has as much physical destructive power as a wreaker, and he uses it to such a degree that their bound to be collateral damage to buildings, just don't call him cute, at all.

He can combine with his teammates to form Monstructor.

History:

Scowl 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 on Floron 2 when space knights were on it and combined Into Monstructor[confusion on Floron 2 ]
