For my take on Humungousaur I made him an actual dinosaur, I made him a t-rex because I thought it would suit him. Humungousaur is 4× bigger than the average T-Rex which would explain his name kinda, ok I thought it would make him cool if he was a humungouse dinosaur. And for his for his abilities, I gave him some of Godzilla's abilities, which means he has Plasma Breath, Nuclear Blast and he can also absorb nuclear stuff like Godzilla did in "A New Empire." That was a good movie, he also has other like his Earthquake Stomp and his ability to make ShockWaves out of his tail.

Abilities-

Plasma Breath

Nuclear Blast

Nuclear Absorbtion

ShockWave Tail

Earthquake Stomp
