"Deathsaurus" is really an amalgam of Leozack and Jallguar, but since they only have a single torso robot to use they're calling it "Deathsaurus." I agree that it's not ideal, but it's a lot cheaper and easier than getting a G1 Liokaiser off the secondary market. Short of TakaraTOMY reissuing the Decepticon Breast Force, this is likely to be the next best thing.
