“Godzilla: King Of The Monsters” unfortunately flopped at the box office after its release at the end of May. A sequel to the 2014 “Godzilla” movie, the 35th installment to the franchise features the flagship kaiju Godzilla in a deadly battle with the Titans.

What gave life to the newest release were not just the visual effects and actors — it was also Director Michael Dougherty’s love for the lore and his Easter eggs throughout the movie. Here are five things you might have missed in “Godzilla: King Of The Monsters.”

Godzilla’s Spikes Change Constantly

A Twitter user asked why Godzilla’s dorsal plates changed, and the director answers that the lizard-like kaiju grows its spikes constantly. “His spikes are constantly growing, breaking, and changing shape, just like deer or elk antlers. Or your own hair,” he answered.

King Ghidorah’s Heads Retain Memory

When asked why Ghidorah’s personality seemingly changed after regenerating a new one, Dougherty said that the Hydra-like monster retains memories and personalities even after being severed. “Most of Ghidorah's neurons are scattered throughout his body and limbs, much like an octopus,” he explains.

Zhang Ziyi Plays As Twins

In a seeming plot hole, Zhang Ziyi — as Dr. Ilene Chen — is aboard the Argo as Godzilla and King Ghedorah battle it out off the coast of Mexico. The scene pans back to the Monarch’s base in China, with Zhang witnessing the rebirth of Mothra. It’s revealed in the end credits that Ziyi portrays two characters: Dr. Ilene Chen and Dr. Ling Chen.

The Chens Have Telepathic Abilities

Dougherty also alludes to Zhang’s twin characters as having telepathic abilities. He explains that they “have a connection.” Although not confirmed whether it is simply the fact that the two are twins, a look into the backstory of Mothra reveals that the monster is guarded by Shobijin — twins who can communicate with the giant moth.

Mothra Is Immortal

The director also explained that the moth kaiju simply will never die, in an eternal cycle of rebirth and death. “#Mothra never really dies,” he wrote via Twitter. “She represents the eternal cycle of birth, life, death, and rebirth. And she knows it.”
