News Power did make a Knuckles, though he doesn't seem as common.
He's classic, but the body shape isn't that great, it's more square with a thick waist. The fists are a little small, but the head shape & face seem ok. Notice his feet though: the fabric is cracked/flaking. It was made from that "leathery feel" light-weigh fabric that has some plastic-ish coating. Clearly, they didn't use a high quality version of the stuff and it's gone bad over the years.
*It's not like the flaking effect is isolated to 'cheap dolls' only, setting something in the sun, wetting the fabric or other poor in-home conditions can cause it to degrade so it's important to take good care of your dolls---but keep in mind that sometimes they can go bad no-matter what care you take.
