It's not so much that Rattrap is a coward... he just doesn't want to die. He's seen enough battles to know the score, so he's not afraid to tell his commanding officer to shove it if he's not fond of the odds. He prefers to sneak around unseen, in gutters or trenches or trash barges or what have you—whatever keeps him out of harm's way. He shouldn't be so worried. When he does encounter conflict, he deals with it masterfully with the arsenal of guns and bombs he keeps on himself at all times. He feels naked without them.
Of course, it's hard to like Rattrap, especially if you're his commanding officer, because he's sarcastic, irreverent and rude. Plus he doesn't exactly smell the greatest, what with the whole garbage-eating thing. He's also not the most trusting or forgiving sort, so he's not the best choice to take on a diplomatic run. He'd sooner shoot a Predacon or Decepticon than talk to them. Despite his tough-as-nails attitude, he has a strong affection for his fellow Maximal Botanica.
Rattrap is an Autobot Maximal that transforms into Rat.
