Chapter 25

As it raised its sinister hand, a blood-curdling shriek came from Dark Samus. Its hand began to glow bright blue, the color of Phazon. It stuck its hand on the control module. Dark Samus' whole body glowed, and Phazon tentacles grew from his hand and ensnared the module, wrapping around it like vines on a rock. The hologram of Halo began to spin extremely fast, and turned bright blue, until it turned black. It then condensed, and reshaped into the holographic form of Dark Samus's head, with ghostly dark tentacles below.

Dark Samus took its hand off the module, and then put its hand out towards the hologram of itself. It moved its hand upwards, and the hologram moved along with it. The hologram's visor then glowed blue, and the hologram disappeared. Dark Samus then turned around to look at its enemies in the next room. It spread its legs and made fists, and its head went upturned as it let out a shriek. With that, the next part of the nightmare came to life.

Up the side of the bridge, an abomination rose, making horrible, distorted, monstrous noises. They were a mix of pale green and light blue, and were in horrible shapes. Some resembled humans and Covenant, some like parasites. Others looked like bags. They protruded Phazon from their bodies, it glowing a powerful white and blue. As they entered, Samus and Chief looked at their backup as they complained about the drop in temperature. Due to their suits, Chief and Samus couldn't feel it. But they knew these things were no pushover. They were Phazon Flood.

Samus and Chief opened fire on these monsters, and their backup did as well. They managed to shoot a couple of them. Then suddenly, Chief held out his hand.

"HOLD YOUR FIRE!" He yelled. Everyone stopped shooting and looked at him, wondering what.

"They're not coming for us." Chief was right. Dark Samus stood in place, his legs spread apart, his arms outstretched and his head held high. The Parasite Phazon flood crawled onto him, and then were absorbed. They became growths on his body, and he grew bigger with each one. As more Flood followed, all of them, all forms, latched onto him and became growths, they became different, new parts of his body.

All of the soldiers opened fire on it, their attacks useless. They eventually all stopped shooting to look at the monster Dark Samus had become. It was no longer Dark Samus. Its head was veiny, with eyes and glowing teeth. It had a muscular body with no growths, with a light blue orb on its torso. It was dark blue, muscular, and veiny. It had three fingers, three toes, a tail with Phazon Tentacles on the end, and Phazon spikes on its shoulders. There were glowing, light blue spikes on its back. It had a light blue aura, similar to Samus and Master Chief's hyper mode. Samus switched to the scan visor, and scanned this new being. According to her visor, Dark Samus had become Monstrosity.

It fired a beam from its hand, which killed one UNSC Marine. All the Marines advanced towards Monstrosity. Samus went into Morph Ball, then came out right in front of Monstrosity, and fired her Charge Beam at the Orb in the center. It merely bounced off. Master Chief ducked, dodging the Charge Beam. It shot at the monster's body, at whatever he thought was flesh. He knew from experience flesh was always the weak point on a life-form. He had no idea why Samus was aiming at Phazon tentacles and the orb in its torso. But Samus knew from experience that whatever stood out on a large monster was always the weak point.

Samus finally fired a missile at one of the Phazon spikes on its shoulder. A crack appeared in the spike. She knew right away that she found the weak point. She sent a message to all marines "Aim for shoulder spikes. That is the weakness of Monstrosity." Everyone followed, and shot at the shoulder spikes. Eventually they were all gone. But before they could do anything, Monstrosity's shoulder spikes grew back, and Monstrosity was not pleased. It opened its mouth, and sent out a Phazon Beam so powerful only Master Chief, Samus, a UNSC Marine and a Federation Marine survived. The beam broke the bridge in half, there was part of it leading towards the door and one leading towards the control module, where Monstrosity and the four survivors stood. They looked at the hole in the bridge that had been created by the beam. The bones seem to be suspended in air for a second, before breaking to pieces and falling down into the abyss below. They looked at Monstrosity, and then jumped back to the other half of the bridge. Monstrosity seemed to merely stand there, staring at its enemies, they didn't know why. Samus saw this as the perfect opportunity to scan Monstrosity more. She did, and then looked at its logbook entry.

"Weakness, weakness, weakness…damn, this thing is too long! Ah! Weakness…subsceptible to…got it! Everyone! Shoot his spikes until they're all gone, and I'll take care of the rest!"

In Metroid Prime 3, when Rundus and the other hunters are defeated, Dark Samus appears in this form and absorbs the Phazon in their corpses. Just so you know what he looks like :D
