Vastatosaurus Rex: https://wikizilla.org/wiki/Vastatosaurus_rex
Stats: Standard Showa Scaling; one V-Rex.
Battleground: the shores of Skull Island.
Verdict: the V-Rex is absolutely screwed here. Speed, intelligence and sheer primal ferocity and aggressiveness are absolutely nothing compared to the strength to pick up a man. This match should be skreeonking locked for how one sided it is.
