Godzilla is returning this summer in Godzilla: King Of The Monsters but there will be some iconic monsters missing.

Continue on to get the from O’Shea Jackson Jr. on why some of the iconic monsters are missing from Godzilla: King Of The Monsters…

CelebNMovies247.com reports Godzilla: King Of The Monsters will bring Mothra, Rodan and King Ghidorah in the upcoming Godzilla sequel but the film won’t be including every iconic monster from the character’s 65-year history.

O’Shea Jackson Jr., who plays one of the soldiers in the film and is a big Godzilla fan, recently said:

I’m gonna’ tell you about my most feared Godzilla monster. One time as a kid, Godzilla was about to die and it was Gigan. Gigan is a problem. There’s like – there’s no way Godzilla should have won. Gigan is a real problem, so I hope we don’t see him, because this is going to be way worse nowadays. But you know, MechaGodzilla. MechaGodzilla is like a hidden gem right now.

Godzilla: King Of The Monsters Iconic Monsters Missing:

It was speculated that what classic monsters might make an appearance in Godzilla: King Of The Monsters, with Gigan and MechaGodzilla among them, but if O’Shea Jackson Jr. those two definitely won’t be part of the festivities.

O’Shea has distinct memories of Gigan, who is one of Godzilla’s most formidable and crazy-looking opponents. An alien cyborg kaiju, Gigan has deadly hooked claws on his appendages, a spiked tail, and vertical spikes that go all the way up his torso. He also has a cybernetic visor for an eye, out of which he can shoot lasers.

Another is MechaGodzilla, one of the more popular Godzilla monsters, at times being both heroic and villainous. He has been depicted as an alien weapon or as a human creation meant to fight Godzilla. The robotic Godzilla is the War Machine of the kaiju, with missiles, lasers, energy beams and the power to fly. But he is another missing from Godzilla: King Of The Monsters. But without those two in the film it leaves it open for another sequel.

The actor has distinct memories of Gigan, who is one of Godzilla’s most formidable and crazy-looking opponents. An alien cyborg kaiju, Gigan has deadly hooked claws on his appendages, a spiked tail, and vertical spikes that go all the way up his torso. He also has a cybernetic visor for an eye, out of which he can shoot lasers.

Though, O’Shea Jackson Jr. said that MechaGodzilla is “a hidden gem.” Jackson has noted that Godzilla: King of the Monsters will have Easter Eggs, so maybe there will be some reference to MechaGodzilla blueprints, or something of that sort.

If you think about it, it’s probably for the best that Gigan and MechaGodzilla won’t be in Godzilla: King Of The Monsters.

King Kong and Godzilla will face off in 2020, but at some point, they will have to team up to fight a common enemy, alien or man-made, so maybe Gigan and MechaGodzilla can be introduced then.

Godzilla: King of the Monsters stomps into theaters on May 31st.
