Zalgo started off as an urban legend, but later, he became a version of Tails.EXE until he stopped using Tails' body, so he stole Sonic's body instead, becoming a version of Sonic.EXE.

Zalgo is the craziest virus in existence. He was created 5 seconds after the Big Bang, when Chuck Norris (who had just created the UnUniverse) was lonely and wanted a friend. He managed to start up a clan, commit genocide on dalmatians, and even destroy an entire UnUniverse! He's basically as scary as my teacher. He's the king of the H4XXORs and he always will be because he's practically immortal. He's also against educational websites (this is why Educator hates him) and will h4x them.

He's always going around cyberspace eating old televisions because he's a cannibal. No one knows what his true form is because he's always shapeshifting into his previous victims.

Recently, he made a bootleg season out of WordWorld, and thus becoming a bootlegger. Due to this, he became a member of the Bootleg Kingdom, but he later left and spawned tons of viruses.
