Take the G1 Protectobot Hot Spot for example. His first toy was a completely new mold created to be Hot Spot but since then the character has only been repaints of other characters completely unrelated to him - the Universe 1.0 Micromaster, the Universe 2.0 Legends and soon the 6" Titanium. They haven't given the character a brand new mold since the original. Many characters seem to be like that these days. And it seems that originally a repaint character, always a repaint character. Some characters have always been repaints of someone else despite having many toys to their name - like Skywarp.
