No, they couldn't just make Soundwave for the Siege line. If you make him, you pretty much have to make some of his minions! And Siege delivers with "Micromasters" Laserbeak and Ravage! The bird and cat spy combo also come with alt modes which aren't just cassettes - they can be used for something else they may not like! Join Death in going over these little plastic rectangles to learn whether Soundwave needs them for company!
Diminutive, sure, but dare I say that the Siege Laserbeak and Ravage might be among the best modern updates we have gotten for these two characters.
