Hexster is the scrapped Scratch mascot, was supposed to teach how to do the program, not just stand like a sprite. In the end, the creators changed their minds and kept the mascot, an orange cat, instead of Hexster.

His creations: Hunzo and Excel.

Hunzo is a creation of Hexster. Hunzo didn't like the way he looked like Hexster, so he decided to change his settings. He redrew his face, added hair on the back, and became very happy, always showing his index finger up. He is now stored in the Scratch files.

Excel is another of Hexster's creations, but he's bigger than Hexster and Hanso and is the eldest. He likes playing the piano and should learn how to write music in Scratch.

His victims: Polytra and Muzzle. They were ordinary people, but they ended up in the Scratch program or in the Hexter world. They don't remember who they were when they were human, but they only remember their names.
