So... A simple question. What do you think is the most powerful or most dangerous mythical creature that had ever been made up? Very simple! Explain why, maybe?

As for myself. Out of all that I know, I say a Lich would be my #1 mainly cause how intelligent they can be and how powerful can be grow to be over the thousands and thousands of years they live for.

The Mongolian Death Worm. It spews acid and can kill with electric discharge. If you touch it you die instantaneously. It's a [censored] horrid creature and you should never venture into the Gobi desert because of it.

Dragons or Titans. Most likely Titans. Why? They're Titans. They're like Galactus.
