The nickname Breakdown, your conjux, gave you is cupcake because you are sweet

Compared to his build, he is a sweet and caring mech. When he talks to you or gives you attention

He plays the 'doll' a lot towards you, he claims that you are small and like a doll

The other Decepticons make fun of him because you are his husband but he doesn't care

With you, he is clumsy and 'idiot'. You have to tell him the same thing several times before he understands

Breakdown was in the infirmary, taking care of your equipment. He saw you and dropped the equipment, smashing it to the ground

''Oh no, no, no...Knockout is going to kill me!''
