The God of Void vs The Guardian of the Universe

Assemble!

Several hours later, it was finally 8:00 PM and the Avengers gathered to see the information behind Fury's death. "This is the spaceship, but this," said one of the scientists, "That's the god of the void." Peter looked confused, "What do you call that thing?" "Ghidorah, the three headed demon. He was somehow sent here to do something. His species is wide spread and he's the largest of his kind so far. But if we don't stop him he can shatter this universe." Tony Stark raises his hand, "What's his origin story on other creatures?"

The alien scientist, named Larry tells the story, "Ghidorah the one that attacked us was 100,000 years old. But his species have been around for an unknown number but greater than a trillion moving from universe to universe. There were multiple Galactus, long ago, before they were killed off. This species, they are described as invasive species to our universe and are here to transform it to their own image. The only help we need is Galactus, but the bad news is he doesn't trust us. This Galactus is young and he's learning how to fight these Ghidorahs. The only way we can win is Galactus winning the battle, by that we need an orb." Captain Marvel asks, "Why don't we just kill him?" "It killed Nick Fury, and it's like a ghost. You can't hurt it, the orb is the only source of power that can break many laws of physics." "And where's the orb," asked Hulk.

He gets up and looks out the window. And sees something passing by the sky. Unknown to him, it was actually Silver Surfer. Larry hesitate and shyly replies, "I don't know where it is. The last sighting was on Titan but it's likely it got teleported to another planet, Ghidorahs use it to lay their eggs, find a female Ghidorah nest and we can use the grab." A scientist cane back and told Larry, "Sir, the orb is located on a nearby planet, but it won't be easy, it turns out Ghidorah is on that planet too." Larry was shocked, "The planet is near Galactus he must be going there soon to find the orb." Unknown to them, in space Galactus is watching them...
