Finally the Hound Kreon surfaces... but is part of the more expensive Custom sets. (each one has about 20 parts to mix & match)
It's a darker green than the one that Hasbro had on display way back at BotCon 2011 (two and a half years ago!), but some fans will be happy that it is finally coming.

Wave 2 will have a couple odd characters thrown in too, after the very iconic first wave...
(Gen1) Cliffjumper
(Gen1) Hound
(Gen1) Jazz
(Gen1) Dreadwing
(Gen1) Galvatron
(BH) Predaking
