Jaguar is a childhood rival to Pixel. Knowing  each other due to a scuffle they had as children. Ever since then they challenge each frequently

His main power is telekinesis which makes him a dangerous opponent with prep time. He is incredibly smart and he likes to show it. Is always one step ahead. Jaguar being very confident in his skills makes him constantly cocky. This leads to him being a very hilarious character with interactions. The one thing cherishes most in the world is his Jacket. Never allowing himself to finish a task if it's stained. Even if he is in a middle of a battle he won't fight till he cleans it.
