Blastwave

Blastwave is an Autobot bounty hunter who, despite unable to talk all that much, is the high-tech weapons base for the Autobots.

History
Blastwave was in pursuit of the rogue Autobot Nightra, who stole his Light Bender and bounty hunter ID badge and fled to Earth.

Following the fugitive, he encountered Bee's team, who believed that he was the criminal and Nightra was the bounty hunter. He fired upon Nightra, causing her to flee and for Bee's team to retaliate. Blastwave mopped the floor with them-using Grimlock as a weapon no less-and then went back to his ship. He tracked Strongarm and Bumblebee's signals as they looked for Nightra. He promptly opened a space bridge right next to them, grabbed Nightra and left. He was placing Nightra in a containment unit when Bee's team came to stop him. Nightra escaped again and Blastwave was thrown in the cell meant for her.

In the cell, Bee's team finally realized that Blastwave was an Autobot, who spoke to them using Cybertronian Sign Language, setting the record straight. He was released and helped save Bee's team from being sucked out into the void of space. A captured Nightra was given to Blastwave by Strongarm as well as his badge and Light Bender. Blastwave was pleased.

Trivia

 * Despite being a fairly extensive retool affecting nearly every area of the toy, Blastwave's card art and on-screen character model are blatantly an unchanged Megatronus body with only a new head and chest.
 * Blastwave holds the first of many Cybertronians to show Cybertronian Sign Language on screen.
