|Ugly Square Guy|
|Relatives||Evil Square Boy (brother), Momma Square (mother), SquareBoy (cousin)|
|Introduced In||"USG and ESB"|
USG is a green rectangular creature with two buck teeth, a blue cone hat with his initials on it, and an angry expression. His arms and legs are small and stick-like, and he is somewhat short. He has a tuft of stringy hair under his hat.
USG is completely the opposite of his brother, ESB. He is perpetually grumpy and angry, hates video games, and is annoyed by ESB's antics very easily. He often complains about his quests, and is somewhat violent especially compared to his brother. He is obsessed with Aeropostale clothing, and is somewhat egotistical as well. He is quite lazy.
