It would be cool if Classified delved further into the pink Dark Energon crystals mined by Mole Rat like they're expanding on Crystal Ball's supernatural D.I.R.E. tech. Dark Energon, for those who don't know, is a reference to Transformers (in Transformers, Dark Energon exists and reanimates bots). It's a little disappointing that we haven't gotten a Toxo-Zombie, Zombie Viper, or anything really hinting at them other than Mole Rat. It doesn't have to be Eco-Warriors redone, but clearly zombies are a large part of Joe history and deserve more than one figure.
Those 50th Anniversary Zombie Patrol 2-packs flew off the Toys R Us shelves not that long ago. I can't imagine a similar modern version not selling just as well. They'd be fantastic foils to Night Force.
