Monster lizard

The monster lizard is one of the mutant animals that was kept by Chu Sing Ling.

History: This reptile was one of the many animals that Chu Sing Ling experimented with his bacteria on Moitu Island and is about 8 ft. tall.

When first introduced, it appears to be an iguana. At the same time, it was also a demonstration as one of Chu's pets held in a cage with a giant spider. When presented, Dr. Quest, who was kidnapped into agreeing his work, was surprised. However, knowing his work is dreadful, Dr. Quest refused to go along with Chu's plans, but is threatened to agree or will die by being devoured by his pets once the cages set to automatic mode have been finished.

After time is up, Race came just in time to force Chu to untie Quest. After a guard appeared, Jade came and knocked out the guard, while disappointed in Race for not listening. After Chu got away through a window and the door becomes locked from the outside, the cages begin to open, freeing the spider and lizard. Before the lizard could get out, Jonny, Hadji, and Bandit suddenly appeared in a bulldozer, crashing through a wall and debris from the impact crushed the lizard.

Another giant lizard appeared, and this one was gargantuan, standing approximately 120 ft. in height. It was first spotted by Hadji when Quest Team were escaping from Chu and his minions. The lizard emerged from the sea and menaced Chu and his team. Searching for food, it chased the villains back to Moitu Island, while Jade describes it as unbelievable. As the lizard reached to shore, the three men start shooting, but didn't prevail as the monster devours them. Chu is cornered by it next to a fence with a high voltage power station. As the lizard approaches him, he walks right into the high voltage wires, electrocuting and killing the lizard. As Chu screams in horror, the high voltage station exploded, destroying Chu in the process and everything and everyone else on that island.
