The opening scene of "Power Battle Watchcar: The Counterattack of Watch Mask" takes place in a dark alley with identical armed men hunting down some old guy in a business suit. So I had to wonder, are they clones, or was the production company just being cheap? Actually I was wrong. They are robots. So of course when the good guys respond by destroying them with excessive violence, that's OK, because robots, however humanlike, deserve all the violence that's coming to them.
Where was I? Oh yeah, so apparently there's this woman called Charles (voiced by Hong So-yeong) who goes around using her robot army to force people to sign contracts to compete in the Ultimate Watchcar Battle League, which is also excessively violent. Oh don't worry. Watchcars are technically robots so using excessive violence on them is OK too. Anyway you'd think using a robot army to force people to sign contracts would be illegal and that they could just call the cops. But no, apparently the only way to stop Charles' evil plans is for Jino (voiced by Eom Sang-hyeon) to sign one of her contracts and...win?
