What is second gear? I never found out what gears are. I didn't bother watching the anime or reading the manga since the series is supposed to last like 15 years or something as the creators said and it is the longest running anime and manga ever so i can't catch up. I seen Luffy use a gear in the arc where they had to save Robin, he was able to copy the guy's moves and beat em, is Gears like Kaio-Ken?
