Bounce

The Mini-con Cyclone Bounce specializes in vandalism such as property damage and graffiti. He isn't very bright but his spherical alt mode is just what he needs to quickly get away from law enforcers like Sideswipe and Blurr.

Transformers Rescue Bots
Bounce was a captive aboard the Alchemor, who was freed when the ship crashed on Earth. After being captured by Sideswipe, he managed to escape through the GroundBridge and landed up on Griffin Rock, where he immediately began adding graffiti everywhere. Pursued by Blurr, he managed to get away when Sideswipe caught up with them and fought Blurr instead of recapturing the Mini-Con. Once the rescue team had a plan, Blurr and Sideswipe again pursued Bounce, but he proved too fast for them and lost them by entering the town's sewer system. He was flushed out by Cody Burns and Servo, allowing Sideswipe and Blurr to drive him into a trap set by the rest of the team. Sideswipe returned home with Bounce safely trapped in a net.

Trivia

 * Bounce is the first Cybertronian antagonist in the Rescue Bots cartoon.
 * Bounce shares a body-type with Backtrack and Ransack.
 * Though Cyclones are initially unaligned, many are shown allying with the Decepticons in the Robots in Disguise cartoon. To that end, Bounce could also possibly be the first Decepticon featured in the series, despite having never been referred to as such.
