Are the bagged 1984 Kenner Super Powers (Flash) on ebay legit?
 

I tried to find out if there was more about these after searching the site, but didn't find anything. I wanna get one if its real, but if its a cheap plastic knockoff I'm gonna pass..

I'm not trying to discredit any sellers just curious.

Here is an example.

here's a pic of an original for sale, my only comment would be the paint on the one in your pic looks almost to good, I had a SP Flash as a kid and his eyes were derpy, the flesh paint went onto the ridge of the mask (like in the link pic) and the lightning bolt belt paint was off. Plus there is no flashing (extra plastic where the mold comes together) on his feet. and the crotch looks a bit different. I'm no SP expert so don't let me poo in your Cheerios, but that's what I noticed. he may be some mail away exclusive or something?

I thought the same but I did do a little research about their mail away, and from what I read it was carded and actually printed on the card that it was a mail away. I also read that they had different companies make these figures for Kenner, so I'm at a bit of a loss trying to figure out whats what. As far as comparing its looks to an original carded figure, they look really good and are half the price. I just want to make sure I buy an authentic figure and don't support the knock off artists.
I have a real one thats beat up enough that I can't compare it to the pictures I see online.

i also had an original, and if im correct there was a wind up mechanism on the box of him that would make his arms move as if he were running.

No wind up mechanism on the original. You squeezed his arms to make his legs move as if he were running. I think the ToyBiz version that came out in the 90's may have had a wind up.
