Jazz is Optimus Prime's Sub-Commander. Unlike Prowl, Prime's military strategist, Jazz responds well to change and improvisation. Whatever surprises the Decepticons spring, Jazz can deal with it. His position as Special Operations head calls for all the skills he possesses, yet he still has time to add some style to everything he does.

An admirer of Earth music of every kind, Jazz loves culture. More than most other Autobots, he has his finger on the pulse of Earth trends and lingo. Chances are, Jazz could tell you the status of almost any reality television show and each week's Top 40 list.

Jazz's personality makes him well-liked among the others of the Ark crew, especially Bumblebee. In fact, you'd be hard-pressed to find an Autobot who doesn't like or admire Jazz. Except perhaps Grimlock, who doesn't like anyone anyway.
