My first pick would be Alpha Trion from the first Generations Scourge mold. He was a choice in a 2014 Takara/Million Publishing fan poll and he just barely lost to Go Shooter from the T30 Nightbeat mold. My second pick would be Defensor from the original Fire Convoy mold. I know we ended up getting a similar repaint with the Titanium RID Optimus but the full size version looked so much better. It got canned when OTFCC lost the Transformers Convention lisence.
