Tomosaurus 

An ancient creature created by one of Tom's less successful time travel experiments. In the near future Tom tries to send himself back in tie to replace Arnie with a young clone of himself, but it goes wrong and the clone goes back 75 million years. A Giganotosaur is the first to discover this lil' clone in the wilderness, but latent temporal warps etc pull them both into another dimension and a genetic fusion merges the two creatures into the Tomosaurus.

At a massive 8000 feet long and with reasonable telekenisis, Tomosaurus is a prime example of how nature + science + insanity = power gaming.

(or to put in Manus-speak, that picture Roxy did for Tom)

You are all doomed!!!!!

Tommysaurus 

Tommysaurus is the name of a person who is polite, friendly, made some bad choices but then who hasn’t? He is super cute and deserves all the respect and attention because he’s a great friend.

That guy over there? Tommysaurus. Love him.

Oh my god I’m so lucky to have a Tommysaurus for a friend.

Titosaurus 

A girl with tits so large that they would be proportionate to someone the size of a dinosaur.

Theosaurus 

The dinosaur god, or the lord of all the great lizards. A unique specimen, the skeleton of which has never been found, but the image of which appears in many of the earliest cave paintings, depicted as a giant bearded lizard seated on a cloud or floating in a celestial environment.

Early Brontosauri used to raise their heads and low to the sky in praise of the mighty Theosaurus.

Later Brontosauri built piles of rubble in homage to him.

So we assume...

Tokisaurus

A scientific failure, named after Toki Wartooth, that experimental scientists had been working on at Dethklok HQ. The Tokisaurus was meant to be a Tyrannasaurus Rex for a Dethklok concert, but during the manufacturing stage, a stran of Toki Wartooth's hair fell into the DNA. The Tokisaurus was immediatley killed after several pictures were taken of it. The autopsy contained scientific information that has been withheld from the public by Dethklok. It's remains are buried at Dethklok Cemetery.

I bought a Tokisaurus collectible at that Dethklok concert
