IMO, action-figure fame means considerable fame that is difficult to rise to.

At next sentence:
He rose to action-figure fame on the pro wrestling circuit.
What does "action-figure" mean? It seems the usual meaning is linked to some kind of toy, doll, figurine... So, in this case, what is this term referring to?
Please, any final assistance as for my last proposal?
An "action figure" is a male version of a doll. For example, Barbie is a doll, but G.I. Joe is an action figure. The reasoning is, young males wouldn't purchase anything marketed as a "doll," so when professional wrestlers or other athletes are turned into dolls, they are marketed as "action figures."
