"Quick personality analysis- Now that's a good one... As he designates himself, Cogger, is the type of cocktail you get, when you kindly ask a bartender in Kaon to surprise you. He's the mixture of a youthful and enthusiastic cowboy, and a senile old hermit... a hermit that secretly keeps an arsenal of doomsday-devices in his basement. Seemingly quite young, but of what information he was willing to share, implies he goes way back, in Cybertronian, and Decepticon history alike. Cogger refuses to tell any specific personal information about himself. Other than vague stories about certain friends, studies and absurd, humorous pub stories, the mech strictly refuses to give out anything personal. After several sessions of attempts, we'd given up on that. If what he claims is true, and this laid-back, young spirited cybertronian truly hides an ancient spark, it would explain several abnormalities of the Decepticon: While he's cheerful and more than eager to communicate, there are undeniable signs of bipolar disorder, and subtle hints of PTSD which, again, given his role in the past stellar cycles of Decepticon activities, is understandable. A friendly advice: Do NOT let him get drunk." -Unknown psychiatrist.
Cogger, by his birthname, "Cringe" of Yuss is a forged mech, and quite a puzzle, if someone is that crazy to seek a reasoning behind his actions. Failing his studies, being recruited in the rising Autobot army and ending up betrayed by his dearest and closest friend are just mere examples on why Cogger decided to don the Decepticon badge, and why he wears it with pride.
Despite looking like a completely harmless nutjob, Cogger left his whimp days behind long ago, not only utilizing his standard war-era weaponry, but also his glitching Transformation-Cog, which he can use to mimic his enemies' weapons, armor, limbs, even their entire body frame.
Due to his skilled and versatile nature, Cogger, to this day, is classified a caretaker/Handy-man.
