B1 Battle droid
A robot the bad guys used in a war. They say "ROGER ROGER" instead of yes, which is the worst. They’re weak, but the bad guys have so many, they might as well be a trashy army.
The robot said "ROGER ROGER" when it was asked if it wanted to fight. It did. And it lost.
The clone army didn’t like the robot. Then the robot multiplied and got revenge.
The robot said "ROGER ROGER" and got crushed. But it was happy.
