>>10965320>>10965279>>10965326Hasbro has the license to produce children toys for boys. Not 1/12, nor 6", or any specific scale.
The license is separate from the collectors market, or toys for adults.
The reason Diamond shit is 7" is simply because their toys are more expensive (because fewer units are made) and to make consumers feel like they're getting their money's worth, they increased the size by 1", which costs them almost nothing for that size increase.
Collector toys also has another seperate license for "high end" stuff, which is basically anything costing more than $60, hence Mezco producing 6" Marvel figures.
And this might just be character specific licenses too, so Mezco/Bandai/Kaiyodo/etc can all produce their own 6" Marvel figures, as long as no one makes the same character at the same time.
