Antagonists from 3 Music Videos

These are the Antagonists from 3 Music Videos.

This is a Multiple Armed Monster from "F.K.O."

after all the Leaf Headed Creatures were fighting

when they became, except Ivan, he was the last one of all

while the Multiple Armed Monster chased Ivan underground,

These are the giant Robots from "Long Vein of the Law"

came from huge Airships when they were arrived and the

Block Creatures were panicking and it's up the Kato

to save the City from these giant Robots,

and this is a Demon Monster 
the monstrous evil black supernatural Beast from "Swan Meat"

made of black Stuff and Sergei was terrified that the monstrous Demon Monster

was gonna eat him, and then Sergei was in the Stomach of the Demon Monster

to bite a Stomach Stalactite that was fleshy to make the Demon Monster

disintegrated and the black Stuff was flying around and then

Sergei survived. 
You know, the Multiple Armed Monster, a Giant Robot, and the Demon Monster
were 3 Antagonists in 3 Music Videos.
You see, there was a Multiple Armed Monster 
and the Demon Monster were Monster Antagonists 
in F.K.O. and Swan Meat,  
and Giant Robots were Robot Antagonists in Long Vein of the Law. 
I think that Demon Monster from Swan Meat reminds me 
of Hexxus from "Ferngully: The last Rainforest" 
especially he has a big ugly Nose like Squidward's Nose.
