From the moment he came online, Dropkick was able to sense shatter's presence elsewhere in the universe, in his quest to find her, he served many odd jobs, developing a sort of "whatever you say boss" attitude about life.
Luckily, he didn't have to go looking for long as shatter found him instead. Truth be told, Dropkick is more of a blunt instrument, not suited for complex cognitive tasks, but he is a worker first and foremost, he works, he provides, its what he does
Even if work includes killing people, he doesn't mind. He welcomes it in fact because killing is simple, shatter is the one with aspirations, Dropkick lives in the now, he doesn't think they're special and belives anyone in his position would do the same things he does.
His height is a source of ridicule from those unaware that triple changers have more powers than just having three modes, shatter and dropkick can each lift entire montains with ease, so bots that make fun of him often end up.... well, I'd rather not describe it, honesty
