IIRC his streak came to an end when he lost two straight Duels in one show. First guy got him to overbalance and step across onto the other platform, and the second guy knocked him off completely! I remember being proper stunned at that as a kid and it was the talk of the playground on Monday morning
I either didn't see it or have memory loss as I don't remember that!
You've burst my bubble now of thinking he was unbeatable lol
