gigantiguana is a massive mutated marine iguana (averaging at 100ft/30m) that originate from the galapagos

their creation was the result of a massive nuclear barrel dump that spilled off the south american coastline after the great war, radiation drifting into the island, and transforming the local fauna

for a long time gigantiguana remained within the galapagos area, but as their population and size spread, they began to expand outward, and can be found as far north as the california coast, though they remain rare up there

most of the time it sticks to a diet of aquatic creatures and mutant plants, but may occasionally attack terrestrial creatures, especially in nesting areas
