Jazz is one happy-go-lucky Autobot. Good-natured and always able to take things in stride, he provides a decent contrast to the more serious demeanor of Ironhide or Optimus Prime himself. He's also a talker, something Ironhide and Prime like to tease him about. He might be the smallest Autobot but he's by no means a coward, willing to take on any foe, big or small.
