I always got confused with this one. It was either jazz or Ironhide. IH always taking charge when Prime was not around or they had mixed up the evil clone from the real Prime. The bots should really keep the 2 of them separate.

But then you have, Prime, telling Jazz to. "Jazz, organize a battle unit, we're going after them"

And Jazz commanding the bots to transform and standing out front of the pack with Prime.

I'm going to say Jazz.
