Yesterday’s Robot was Generation 1 Huffer. Today toy is the Kreon version of Huffer. He’s from the series three KRE-O Micro changers. The Micro changers let you build either the robot or vehicle version of the characters. I like the grimace on his face. The torso paint is better than the Prowl Kreon. When the Micro changers were released I said I liked the parts but wanted more painting details. Huffer has more details and I still love the helmets.
Both Figures together for comparison , 1984 and 2013 versions of Huffer.
