Komodithrax is a giant reptilian monster who appears in episode 6 of the second season and 27th overall of Godzilla: The Series, titled "End of the Line." She is Godzilla's mate. During a romantic cruise in Alaska, Nick and Audrey's ship was attacked by a Giant Turtle. The two ended up on a deserted island where they were attacked again by the Giant Turtle, but this time they were saved by Komodithrax, a mutant Komodo dragon. Nick discovered that Godzilla and Komodithrax were actually mates, and that Godzilla was acting as a surrogate father to Komodithrax's unhatched egg. Unfortunately, the U.S. military arrived on the island and ordered an air strike to destroy all monsters there. The Giant Turtle arrived again and fought Godzilla and Komodithrax. During the battle, the airstrike caused the Giant Turtle as well as Komodithrax and her egg to fall into a fissure. Godzilla woke up after hearing her final roar, then mourned her death.
TriStar for GODZILLA: The Series, which led to this beautiful couple. @KingTyroRex for the Zilla Jr. in the thumbnail. Credit me when used.
