Stepper is a remold of Jazz, the spoiler has been remolded to facilitate the Targetmaster. The black and gold deco really pops and has been used on classics and alternators figures.
Stepper's vintage figure was severely reduced in the amount of accessories compared to Jazz, there is a piece that goes into where the shoulder launcher also went and you can mount the Targetmaster.
This custom Artfire I snagged off of ebay came with another Stepper Targetmaster instead of a Fracas like Scourge. But I'll get that fixed sometime. He's a redeco of Inferno. He came with a small part that mounted the Targetmaster to the ladder, this one is a cut up Stepper one as well.
For my purposes, this works great, Looks the part and will stand decently in for a real one. In bot mode he's supposed to have remolded fists to carry the Targetmasters. He doesn't come with the missiles usually.
Another thing I liked about this custom was the custom box.
They are pretty nice. The colours just pop and they stand out on the shelf.
