We first saw these blind bagged Transformers Kreons last year in the preview series, and now the first official full series, known as Collection 1, is showing up at retail.
I didn't have it with me at the time, but as with the preview wave there is a code to decipher which Kreon is which. Check out the last two numbers of the code at the top back of the bag to figure out what you are getting:
22981 40 - Singe (Turbomaster Scorch)
22981 41 - Inferno
22981 42 - Autobot Springer
22981 43 - Warpath
22981 44 - Quickslinger (Slingshot)
22981 45 - Rampage
22981 46 - Insecticon
22981 47 - Blast Off
22981 48 - Decepticon Hook
22981 49 - Dirge
22981 50 - Airachnid
22981 51 - Decepticon Bludgeon
I'll post pics of the minifigures later (probably after I go back and try to get my last couple must-haves!), but for now I wanted to be sure everyone had their cheat sheets ready to go!
