Hot Rod, Cyclonus, Kup, and Scourge. Of these figures, Hot Rod was the only one I owned as a kid. A fragile piece, too. That piece in the back that were his wings/windshield broke of shortly after I had him. Not just me, either. I don’t know of many kids who didn’t have a Hot Rod with his back plate affixed via rubber band or glue. New Hot Rod is a little better, but his arm does tend to fall off. The other three are some of the most solid Transformers I’ve ever owned. Cyclonus is a joy to transform. I love Kup’s great looking alt mode and his grumpy personality in bot mode. And I basically bought Scourge just because of his alt mode, which is the Boeing Blended-Wing-Body concept plane. Much better than the “flying bathtub” from his initial G1 design.
