Cobra 5-Pack- Meh. Not a fan of the Valor Vs. Venom inspired SS, nor the black CC. I like the comic-colored Blueshirt though, and the Stinger Driver rocks as well.
Wave 2- I love Buzzer and Serps, but other than that, nothing really that interests me.
Wave 3- The Red Ninja is pretty cool, and I like the comic Stalker, but that's it.
