Marvel: Monster Zero

Peaceful time gives birth to corruption, Corrupted time gives birth to Cruel, and the Cruelest time gives birth to heroes. That's the cycle of nature.
But what about the monster who always opposes heroes? Aren't they also born into the Cruelest time?
What made them into what they don't want to be?
It's my life that I became a monster who is the nemesis of heroism. I will demonstrate to you what I can achieve as a monster. Now the whole world, you have to face this monster, I'm not an ordinary monster but Monster Zero King Ghidorah.
