The earlier figures were supposedly more kid-oriented, even ones like Alley Viper, who really wasn't. So they didn't have stands. Later figures got stands. Yeah, it makes no sense. Especially when you figure the Dollar General Joes even come with stands.
The FF robot was HERBIE
, who replaced Human Torch in the 70s cartoon. Everyone thought it was because they didn't want kids lighting themselves on fire, but it was really that Marvel had already licensed Torch to another company and he couldn't be in that show.
The Firefly motorcycle is surprisingly awesome, BTW.
