The series follows the Humanitarian Environmental (or Ecological, in “Area 51”) Analysis Team (HEAT), a research team led by Dr. Nick Tatopoulos (voiced by Ian Ziering) as they battle giant mutant monsters that frequently appear in the wake of the events depicted in the 1998 film Godzilla. Dr. Tatopoulos accidentally discovers an egg that survived the aerial bombardment before it hatches, in a minor change from the ending in the 1998 film. The creature hatches after Nick Tatopoulos stumbles onto it and it assumes him to be its parent. Subsequently, Dr. Tatopoulos and his associates form a research team, investigating strange occurrences and defending mankind from dangerous mutations. Godzilla, the only hatchling of its species to survive in the movie, imprints on Nick and becomes the main weapon summoned against the other mutations encountered by the human characters. The series also introduces two new characters: Monique Dupre, a French secret agent assigned by Philippe Roache to keep an eye on Godzilla and H.E.A.T., and Randy Hernandez, an intern of Nick’s who specializes in computer hacking.
