In 1998, Godzilla: The Series, a Saturday morning cartoon (not to be confused with the earlier The Godzilla Power Hour), continued the story of 'Zilla's surviving offspring from the 1998 film in a role reminiscent of the Japanese films of the late Shōwa era.
The series revolves around the only surviving offspring of the first 'Zilla seen in the climax of the 1998 film. After the original monster was killed, Niko "Nick" Tatapolous the NRC scientist who first studied 'Zilla convinces the military to conduct a search for any eggs that may have survived. Nick offers his assistance, and ends up falling into a small cavern containing amniotic fluid and one large egg. The egg immediately hatches, though the infant does not attack, and escapes by burrowing to safety after Nick scares it away.
Nick's wish to capture and study the infant is met with opposition by the military who wish to destroy it. With the help of Dr. Mendel Craven, Elsie Chapman, and Randy Hernandez, Nick sets a trap for the infant. Unfortunately, the trap was designed for something the size of a human; the hatchling had gone through a rapid growth spurt and is now 35 feet tall. He quickly destroys the trap and snatches Nick. However, before he can eat Nick, 'Zilla detects the scent of his own kind on Nick and releases him. Nick realizes that the infant had imprinted on him, believing him to be his parent.
Over the next few weeks, HEAT studies 'Zilla. They realize that he is sterile. Unfortunately, Monique Dupre, a French secret agent assigned to monitor HEAT's activities, tips off the military, who immediately attack and apparently kill 'Zilla. HEAT has no time to mourn, as they have to go to Jamaica to investigate reports of people being attacked. They get ring side seats as giant squids attack the HEAT Seeker, but 'Zilla, who had survived, now fully grown to 180 feet tall, and followed HEAT, quickly deals with the squids.
Not long after, HEAT discovers that another creature was responsible for the attacks, a giant, mutant, tar-eating crustacean called Crustaceous Rex (or "C-Rex"). After an intense fight, 'Zilla manages to collapse a cliff on top of C-Rex, apparently killing it (since it returned in the three-parter "Monster Wars," it seems the mutant was only buried and managed to escape). Major Hicks, an army commander and recurring character in the series, is persuaded by Nick that having "at least one mutation" on the side of humanity is a good thing, and orders his men to stand down and let 'Zilla remain free.
