The shorter tail may be indicative that this toy has superior balance to G1 Trypticon completely relies on the tail to remain upright when standing and walking. G1 Trypticon is very much a tail dragger, which is technically incorrect for a dinosaur (and remember that Trypticon's name in Japan is Dinosaurer).
Good call!I can't think of any other redeco potential. Scorponok would be impossible because the design is completely different. Although a Titan Class Scorponok could be redecoed as Double Punch.
