Next to the JP version, which they called Leo Prime...



It's worth noting that the official images of Thundertron, have the robot chest bits wrong. The white panels are supposed to slide down, so that the clear panels on each side of the robot head can fold down further, revealing the robot head more.... otherwise you have several parts and hinges that don't get used in the transformation.

(BTW, ignore anything positive Christalcase says about this toy... It sucks so bad, the transformation is simpler than Beast Era Cheetor - which at least looked good in beast mode, unlike this one.)
