I'm back! And recent chapter of RWBY was ok.

Villains: Raven I'm hating you more and more. Still all the insults were good.

Menagerie: So that's how the weapons of the Albain twins work; using fire and wind dust; not bad. And we're going to get the confrontation we've been waiting for: my Kitty vs "Notice me, Blake-Sempai!" What? It was funny.

Anyway, next chapter!

(Play Primeval Theme)

There's a black background and shards of glass floating in a sphere formation.

Shards come together to form two pairs: one an image of Ruby Rose, then of a screeching Velociraptor.

Two more pairs form an image of Weiss Schnee then of a shrieking Troodon.

Two more pairs form an image of Blake Belladonna then of a Dinofelis leaping towards the screen.

Two more pairs form an image of Yang Xiao Long then of an Ankylosaurus flailing its club.

Two more pairs form an image of Darrel Maximus and a T-rex roaring, jaws glowing light blue.

Two more pairs form an image of Isaac Von Reinhbach and Woolly Mammoth trumpeting in a blizzard.

Two more form an image of Matthew Lewis then of an Utahraptor leaping down, the sun behind it.

The last pair forms an image of Dalton Goldenrod then of a Megalania running towards the screen, hissing.

All the shards come together to form RWBY with Primeval below it before all the shards scatter.

WF Base

Several White Fang Grunts inserted the DNA of a T-Rex, Velociraptor, Triceratops, Stegosaurus, and an Ankylosaurus into the DNA chamber and Cinder began the hybridization.

Several hours later, a pair of blue eyes gazed out of the glass, the door swung open, and the Frankenstein of a hybrid stomped out.

Its head is T-Rex like but with a Triceratops frill and brow horns. Its body has Ankylosaurus armor covering most of it all the way to the tail and the tail ends in a club with spikes on it. Arms are long and powerful with 3 sharp claws. Legs are like those of a raptor, complete with the killing claw.

Its head is red, minus a yellow spot around the eyes and so are its feet. Horns and spikes are coal black. The scales that aren't armor are a dull gray.

The whole animal is 14 meters long, 6 meters tall and 6 tons.

"Ultimasaurus,the ultimate hybrid."Cinder said with absolute malice.

They hybrid let out a blood curdling roar and it charged out of the base, destroying anything in its path. It's target: Darrel Maximus!

Noon

Emerald Forest

Teams RWBY & DIMD are on patrol together. "So Darrel, I noticed you had moved various prehistoric robotics to Beacon Grounds; why?"Weiss asked, a little uneasy.

"I feel like something big is going to happen soon; something that will test all of us. And we'll need every resource we can get."He said, sounding like a certain general. "And did you have permission from General Ironwood to do so?"Weiss inquired, curious. "He said yes as he too can feel it."The shape-shifter added.

Suddenly, they felt the ground shake. Erupting from the trees, was the Frankenstein that is the Ultimasaurus!

"Guys, buy me some time while I look for a weak spot on this thing!"Darrel shouted, dodging its hits from its various attacks.

Ruby got up into a tree and started firing shot after shot from CR, but its armor was too thick. "Ok the armor is too thick for bullets!"She yelled.

"Then let's try this!"Weiss and the others fired off various dust rounds at it, which managed to disorient it.

Yang and Dalton leaped onto its back and started punching/hammering away at its armor to try and crack it. The hybrid howled and then shook them off, their aura saving them from serious injury.

Ruby, Blake, Isaac, and Matt ran under it, trying to slice it open though were only able to inflict superficial wounds to it because of its massive size and thick hide.

Weiss then tried one last thing. She stabbed her rapier into the ground, and a large glyph with swords pointing in cardinal directions appeared in front of her. And then, she was able to summon the Armored Knight at its full 20 foot tall height with its massive sword.

The knight faced off against the hybrid which swung its clubbed tail at it, but with lightning reflexes, its sliced off the tail and the hybrid howled in pain. The knight then used very precise slashes to cut off its armor. The Frankenstein of a beast was now breathing heavily, suffering from heavy blood-loss.

"All yours, Darrel!"Blake yelled.

Darrel turned into a Giganotosaurus and with a roar, he charged jaws agape. He tackled it, knocking it off balance and then swinging his tail at its legs, sweeping it off its feet. He stomped on its arms, breaking them and then pinned its head down with one leg and its legs with the other. He thrusts his massive head into its chest cavity and back out, tearing out its heart. The hybrid went limp, dead.

Darrel then roared in victory. Blake rolled her eyes. "Show off."

Well guys, this is it! We're approaching the finale of this story: the Indominus Rex Arc is upon us!

Until then, R&R my friends!
