Cosmos is Swerve's casemate but I'm way less excited about him. Mostly because, well, we got a pretty similarly-sized Cosmos a few years ago. It's kind of like a partial upgrade. The rest of my malaise is that I'm in a pretty strong More Than Meets The Eye groove at the moment, toy-wise, and Cosmos is kind of the odd guy out. In the current comics, Cosmos is a pretty big guy! (as you'd expect a guy who transforms into a spaceship to be, probably) And this is a small toy, albeit marginally larger than the other one. I also think this design isn't quite what's in the comic, either, though it's hard to tell. Cosmos mostly likes to be in the back of big group shots.
That said, it's still.. an upgrade! I mean, it's clearly a better-looking robot and a slightly more interesting saucer mode. He's a bit larger and he comes with a little Micromaster guy. The Micromaster parter transforms from robot to shuttle to weapon and is clearly supposed to be Blast Master despite being named Payload instead. This guy's pretty cool. I like him.
Cosmos himself isn't bad or terrible, but he kind of feels like a rerun. I'm sure there are some Star Wars collectors out there rightfully mocking my tears as they buy their sixteenth Han Solo with better-painted belt buckles or whatever, but oh wells.
