Another set of Walmart listings that are a bit on the left-field side of things...
These are assortment listings, which would be for different size classes... but since they already have Kingdom listings, could these be for the toyline that will be replacing Cyberverse, because we don't know yet what will be the "younger demographic" toyline will be for next year.
If it was for the Generations toys that were "headmasters", it is more likely that it would be listed as "Titan Master".
There will be a lot of speculating until we get some actual product leaks or official announcements.
