Monster X

Monster X was an alien monstrosity controlled by the Xilliens and served as their trump card against the mighty Godzilla. Like many Ghidorahs, he arrived on Earth inside an asteroid which Godzilla destroyed just as it entered Earth's atmosphere unintentionally releasing the monster within.
Their battle commenced without delay and fought until X crushed Godzilla's arms and brought the King of the Monsters to his knees, wailing in horrible agony. But just as X started to win, he was attacked by Mothra, who had come to aid Godzilla in battle but she was attacked by a new and improved version of Gigan.
After Gigan killed her, X and Gigan managed to overpower and nearly kill Godzilla when two buzz saws Gigan had used to kill Mothra decapitated the cyborg, leaving X to fight alone. After several more rounds of fist fighting, X and Godzilla split up and fired their long-range energy blasts at one another, causing a massive explosion that knocked both monsters to the ground.
When the Xillien who had usurped the position of Controller from his predecessor died, he transferred all of his godlike powers into Monster X who began to transform before Godzilla's very eyes.
Keizer Ghidorah

After being infused with the Controllers powers Monster X got down on all fours, sprouted wings, enlarged the proportions of his body, changed his white skeletal armor into a stronger dark gold armor, elongated his neck and allowed his shoulder skulls to fill out and become extra heads.
Monster X was now a thing of the past, only Keizer Ghidorah remained and he was even more powerful than Godzilla could have imagined. With the fate of the world hanging in the balance, Godzilla engaged Keizer Ghidorah in battle and tried to procure an immediate advantage.
But Keizer Ghidorah's gravity beams managed to tear through Godzilla and knock him to the ground where the continuous stream of golden lightning bolts dragged the King of the Monsters across the ruins of Tokyo and then lifted him up close enough to Keizer Ghidorah that the space demon was able to bite into Godzilla with all three heads and begin draining Godzilla's power.
When all hope seemed lost, a young man named Okazaki, who possessed the same godlike powers that the Controller had charged the Gotengo's maser drill using his own abilities and transferred a great deal of power into Godzilla, allowing him to escape Keizer Ghidorah's grasp and use his atomic heat ray to blow the space demon's right head off just as it was firing a gravity bolt which Godzilla managed to redirect at the left head, scorching it.
The mangled Ghidorah collapsed to the ground, writhing in agony, unable to stop Godzilla from hurling him into the sky. Using his spiral heat ray, Godzilla blasted Keizer Ghidorah into orbit where he exploded, ending the threat posed by the Xillien's trump card.
