1. TIE G1 Blitzwing and G1 Grimlock, for being my childhood favorites and now part of my collection. 2. RiD Scourge, because I just love LOVE Nemesis Prime and it's the best of the bunch (this spot is in danger of being replaced by MP OP Sleep Mode if I ever want to shell out $200 for it) 3. G1 Predaking, because I think it's still the best combiner ever.
