Chief is a SPY Fox character in SPY Fox 2: Some Assembly Required and SPY Fox: Operation Ozone. He has the same voice actor as Professor Quack and the Snowflake Inspector Detector from Pajama Sam 2: Thunder and Lightning Aren't So Frightening.
Chief is partially unseen because his body is never shown in the SPY Fox games. All we see is his left arm.
- Chief is almost similar to Inspector Gadget villain Dr. Claw since all we see are their arms.
