I've not got into the Kreons, but that Autobot Spike Kreon is pretty cool. And this might be the only way a Robot Master toy is ever created.
The little "Waspinators" as pilots for the bigger "Waspinators" is an interesting idea too and way to make use of a character getting two very different Generations toys lately.
The theme though seems mixed which is nothing unusual I guess. Unreleased/produced concepts, a bunch of Diaclone references, and Battletrap.
Not overly sold on the names Burn Out and Lift-Ticket (discovered this is a GIJoe name) but they are growing on me as part of the "extended" G1 universe (even if these two mechs technically aren't Transformers).
