Zilla 1998

In Movie
Godzilla (ジラジ Gojira?) was a daikaiju created by TriStar Pictures that first appeared in the 1998 film, Godzilla, and subsequently reappeared in the sequel series, Godzilla: The Series as Mechazilla.

Godzilla

A giant reptilian monster swam from the islands across the Pacific, attacking the cannery ship Kobayashi Maru, and then stomped across Panama.

From there it traveled up the American Eastern Seaboard, where it sank several American fishing boats. Later on, the creature arrived in New York City, wandering through the city and causing major damage. Eventually, it was lured into Flatiron Square with 20,000 pounds of fish. After escaping a military attack, the monster stomped through New York, necessitating the evacuation of the entire city. The monster was later labeled "Godzilla," after the lone survivor of the monster's attack on the Kobayashi Maru identified it as "Gojira." The military battled Godzilla extensively and seemingly killed it in the East River with torpedoes.

However, it had laid 228 eggs in and under Madison Square Garden (an arena in Midtown Manhattan), which hatched and filled the Garden with hundreds of infant Godzillas. The military bombed the Garden, slaying the infant 'Zillas. However, Godzilla then revealed itself to have survived, bursting up from underneath the street, and, after seeing its dead offspring, chased the heroes through New York across the Brooklyn Bridge, where it became entangled in the suspension cables. It was then killed by F-18 Hornets.

One unhatched offspring survived the destruction of Madison Square Garden. When it hatched, it imprinted upon Dr. Niko Tatopoulos shortly after the doctor discovered the egg. From there, the new Godzilla accompanied Tatopoulos and his team, H.E.A.T., on their missions against various monsters mutated by nuclear experiments in Godzilla: The Series.

In a recap of the ending of the 1998 film, Godzilla is killed on the Brooklyn Bridge by three F-18 Hornets.

Monster Wars: Part 2
After his death, Godzilla's body was taken to a military base where it was studied. The base was eventually overtaken by Tachyons, who used their technology to resurrect Godzilla as a cyborg called Cyber-Godzilla.

He was then sent to eliminate H.E.A.T., who had sneaked into the facility, and when his son, the second Godzilla arrived to save them, he refused to fight his father and was taken under the control of the Tachyons. The father and son team gave chase but were distracted by N.I.G.E.L., which allowed H.E.A.T. to escape.

Cyber-Godzilla and the other mutations under Tachyon control were then sent out to various cities to destroy them. Cyber-Godzilla was chosen for Tokyo.

Monster Wars: Part 3
The other mutations were saved from the control of the Tachyons, with the sole exception of Cyber-Godzilla who remained loyal. He soon confronted his son, who decided to fight for his surrogate father, Niko Tatopoulos, rather than his biological father.

The two began to fight, ultimately ending with Godzilla tearing off Cyber-Godzilla's robotic arm and ripping open his torso, pulling out his vital circuitry and finally killing him for good.

Godzilla, Mothra and King Ghidorah: Giant Monsters All-Out Attack
Although not appearing physically in the movie, a monster resembling Godzilla that had appeared in New York was recognized by humanity and General Tachibana. Japanese scientists considered this monster different from Godzilla, in spite of American scientists' disagreement.
