Original source here Checked the resources and saw that there were no official images for Thundercracker and Mudbuster Bulkhead Also comes with bios in the 'details' tab. Mudbuster Bulkhead Bio: Sneaking has never been one of the things at which BULKHEAD excels. He prefers to change directly into action, causing as much chaos as possible. When he discovers the CONTSTRUCTICONS™ up to no good at a local construction site, that’s exactly what he does. Mud and debris spray up from his wheels as he speeds into the middle of the site, ready to smash DECEPTICONS® with his wrecking ball. Thundercracker Bio: STARSCREAM® has a bad reputation for being arrogant, but his clone THUNDERCRACKER has perfected the art of being self-involved. He’s absolutely convinced that he’s the best looking, most talented, most dangerous robot ever built. He refuses to work with most other DECEPTICONS®, arguing that they just make him look bad.
