Three

Three, like her counterpart Thirteen, was one of Malovus' successful experiments in creating a living bioweapon. She was named "Three" by Seven, who gave himself a numerical name after learning that Thirteen had done so. Seven and Three managed to escape Malovus' Laboratory, and Seven practically coerces her to work with him in bringing down Malovus and Thirteen.

She is set to appear in The Unluckiest Number.

Three appears to feel no emotions while in truth, she is internally conflicted. Despite abuse from Seven, she remains loyal to him.

Three employs the use of magic and Archic sorcery in battle, unlike Seven and Thirteen who use enhanced physical strength.
