Just bought Prometheus and Wb-03. I already own toyworld dinobots, Poseidon, Ordin, Nero Rex, and UW Devy. Decided I'll go with Havoc instead of M3. Hades no thanks and Uranos looks horrible to me. Throttlebots no interest. I will be keeping my UW Bruticus, Computron, Superion, as well as Liokaiser and Victorion. That should be more than enough to keep my combiner collection on hold and my wife will like what I get. But eventually my collection has to stop. Back on topic, M3 is awesome looking. But I need one of my Stunticons sports cars to have those 6 wheels for some accuracy. But I hope the M3 owners continue to love him!
