As a kid, I never had the Defiant. It came out later in the ARAH run (1987) and I was growing up and leaving Joe behind at the time. Although I was aware of its existence, I did not really notice it until I started collecting as an adult. Like many, it is part of my list of large playsets to acquire when I have the means and the space to do so.
In the meantime, I turned my attention to the crew. One of the more obscure characters from that period was definitely Hardtop. He did not really get much media exposure at the time and he certainly was not as exciting for kids as his Astronaut partner Payload (also included with the Defiant).
Still, when a buddy of mine asked me to make him a modern version of Hardtop, I thought it would be fun. This one will soon be traveling to his new home. However, I ended up liking the result so much that I'll have to make another one for myself.
