This version of Ultron from "Avengers Age Of Ultron" is the exact same figure mold that was used in the original "Build-A-Figure" (referred to hereafter as "BAF") figure from the 2015 "Ant-Man" series wave, which consisted of 6 figures in the set. Since Marvel and Hasbro seemingly wanted to eventually give this Ultron figure a wider release, it was only natural that they do so by including the Ultron character in the "Marvel Studios: The First Ten Years" series wave. The main differences between this version and the original BAF version are that this version has a darker silver tint to it, as well as more paint details, such as red lines/marks which were not seen on the BAF version. If you didn't have a chance to add or build the original Ultron BAF from 2015, this version of the figure is a more affordable option, especially if you can get it under $19.99.
