User blog comment:Yatanogarasu/Buggy's Letter from the Government/@comment-1951461-20100728002244

I think that he was invited to become one of the Shichibukai because there a many spots open which could break the balance of the three great powers. I mean, even when Crocodile was stripped of his title the government wanted to find a replacement fast because they feared the balance would collapse. Also considering Buggy took the most footage time in the war the world might think he has skill. Plus the Government might just sacrifice him like they did with Moria.
