Jazz

He does Special Ops for special Ops.

Jazz is Optimus Prime's right-hand man. 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. Jazz's upbeat and outgoing personality makes him one of the most popular Autobots among the Ark's crew.

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, effortlessly incorporating human slang into his vocabulary. Chances are, Jazz could tell you the status of almost any reality television show and each week's Top 40 list.

Here's the thing—you make a mistake when you're playing jazz, you do that mistake again, then again. You make it part of the tune... until it's not a mistake anymore.
