- "And I'll form the left leg!"
- —Bob Left Leg
If you ever need somebody to transform into a left leg, then Bob Left Leg is your man, er, bot. It's what he does, and he's good at it. There's nothing he doesn't know about turning into a left leg. As soon as the call goes out, he'll be there, turning into a left leg for whatever massive robot needs it. Even if there isn't a giant robot, he'll gladly turn into a left leg anyway, just in the off-chance that you need one.
No, he can't turn into a right leg. Or even an arm. Just a left leg, and that's all.
It's a good thing then that he's a part of Team Annoyicus Maximus and does indeed turn into the left leg of the larger robot. This means that the Customercon Combiner has the best damn left leg it can get.
He could turn into a tank, sure, and definitely blast stuff with his guns. But that's not what's important. What really matters is his ability to turn into a left leg. It's almost like he really doesn't have a life beyond turning into a left leg or something.
Bob Left Leg turns into the left leg of Annoyicus Maximus. What more do you need?
