Zalgo

I, Z̤͂â̢ḷ͊g̹̓ȯ̘ (Full name: Z͠a̛'l͘ga̶t҉ot̡h) was an internet phenomenon who all of the sudden became a creepypasta.

Why I'm Awesome

 * 1) I am scary to the point that I am best described as the ultimate embodiment of horror on the internet to the point I became a famous meme.
 * 2) As a creepypasta, I am the one who lurks behind walls!
 * 3) I corrupted several pictures and comics and corrupted them just for the audience's pleasure!
 * 4) Continuing with the scary theme, I am a unique, yet abominable being with seven mouthes, two of which are located on where the so-called eyes would be. Unique isn't it?
 * 5) *Six of which speak in different tongues, and the seventh sings a song that will end the world.
 * 6) Because I perfected my scariness considering I'm a creepypasta, my memes ended as funny.

My Flaw

 * 1) Because I am the Ultimate Evil and King of Nightmares, I torture a lot of people a la Thanos, except worse.

Trivia

 * I am the very first character whose name starts with the letter Z, the very last letter of the English Alphabet on the wiki.
