K is one of main antagonists and a former member of the S.K.A.T. Police, then called "Agent K." K quits his job once becoming the Vice Master, and relies solely on Vice to steal for his living. He usually has a creepy demeanor, but sometimes bursts into pitiful rages. K is admittedly weak, and could faint quickly in a direct fight. In his past life he was nicknamed The Unemployed Emperor as he was the emperor, but didn't do anything productive and spent the tax money on what ever he felt like.
