Agent Juicebox is Agent Sparky's twin, and he is practically the polar opposite of Sparky. He tends to be far more reserved and laid-back, but when he's on the job he is suddenly cold and intimidating. He doesn't truly mean it, though, that just means he's focusing.
He has the ability to control any liquid, from water to blood. He often wears green clothing and he usually has an apple sewn onto his clothes. He seems way more cold than Agent Sparky, but he loves his team dearly.
