The figure set for Movie 12 has Heatran, Monferno, Staraptor, Bronzong and the main groups pokemon besides Chimchar, Staravia, Buizel, Happiny, Sudowoodo, Buneary, and Ambipom. Since Heatran's in the movie it looks legit so far.
Monferno and Staraptor could mean Chimchar and Staravia evolve by then and that is why Chimchar and Staravia aren't in the figure set
