Melissa Benoist is getting her very own action figure as part of Mattel’s DC Multiverse wave 3. She will come with a piece of the Doomsday build-a-figure and will be hitting shelves by the end of the summer. Others in the wave are Doomsday Superman, The Dark Knight Returns Robin, and The Dark Knight Returns Armored Batman. If looks like you will have to wait until the next wave to complete your Doomsday figure.
