Ultimasaurus vs Vastotosaurus

This is the third death battle by Ishan a.k.a Shall-I.

Description
''Genetics and evolution are the two methods to create creatures even worse than the real thing. These are two nightmarish "improved" T-rexes. But it's time for only one to stand!''

Interlude
Wiz : Planet Earth is a great ecosystem of life. Plants, those who eat plants and -

Boomstick : Those who are fierce, brutal and eat everyone else!

Wiz : If you think there are many of those today, several of the prehistoric predators make them look like chicks.

'''Boomstick : And no prehistoric predator is more iconic than Tyrannosaurus Rex! Does it logically make sense to have an advanced version?'''

Wiz : Like Vastotosaurus Rex, the Ravager Lizard King of Skull Island.

'''Boomstick : And Ultimasaurus, the ultimate lizard! He's Wiz and I am Boomstick!'''

Wiz : And it's our job to analyse their weapons, armor and skills to find out who would win a death battle.

Intermission
Wiz : All right, the combatants are set. Let's end this debate once and for all.

Boomstick : It's time for a death battle!!!
