Known as The Lightning Bolt, Blackwell will make his debut on the show as a quiz master on February 26.

The American born 30-year-old starred in the U.S version of The Chase and rose to fame for his ability to deliver rapid-fire answers to questions.

According to the report The Chase Australia, one of Seven’s best performers, is losing ground with Nine’s quiz show rival Tipping Point in the metro ratings. 

The trailer teasing Blackwell’s debut has host Larry Emdur asking the question: ‘You think you know fast?

It then compares Blackwell’s speed at answering questions with a rocket, a racing car and Japan’s the Bullet Train.

The Lightning Bolt is later seen in action on the show, and his replies come so fast that Larry Emdur does not have time to finish questions, and are all correct.
