Currently their is no leader sized toys in the Prime toy line. The Two Maximus toys are selling at the $39.99 Leader price point in American retail stores. Maximus toys have the height and bulk of the Leader sized toys. Leader sized toys since DOTM. Have had a Optimus and Bumblebee in the assortment. I say by default,The Maximus toys are the Leader sized toys in the Prime toy line. Powerizers is the new size name for Voyagers. Weaponizers is the new size name for Ultra sized toys. Maximus seems like the new size name for Leader sized toys. Perhaps Hasbro felt the bigger more exspensive toys needed to be designed for younger kids. Hasbro might have taken away the high detail and complexity of the Leader sized toys. because younger kids found them too overly complicated and scarry in design.
