Re: Why is Baltromeo a super rookie?
Okay so, no...
Firstly, 2 years ago, a group of 11 newbies entered the Grand Line with their crews and, through wrecking havoc and other villainous deeds, reached the end of the Paradise with a bounty of over 100 Million. This was unheard of, and, what was even more especial, was that all 11 of them were, at the same time, in the Sabaody Archipelago. The 11 pirates were then named the 11 Supernova, for the bright stars that grew insanely fast. All together, they turned the Archipelago on their heads, punching a World Noble, ruining a Slave Auction house, fighting a Shichibunkai, and Admiral and ruining several Pacifistas.
When they left, they were entitled the Worse Generation, following events of the Marineford. They then moved to the New World where they were expected to wreck even more chaos. Again, they were the Supernovas, there isn't anything of the sort. Previously, one or another more charismatic pirate would reach a peak of popularity, like Cavendish, but not 11, and as big as each of them.
Past the 11 years, and after many made a splash, while still considered the Worst Generation, most of them grew inactive, or, at least, away from the public's attention. This prompted other pirates to take action, and hoar the spotlights. A few of them reached the 100 M mark, which is something of an achievement, like Caribou and Bartolomeo, but these were isolated events. So they became known for themselves. No doubt the term Super Rookie was coined on Bartolomeo, to distinguish is exponential growth from zero to over 100M. I can even bet that the growth were instantaneous, his first bounty being already that high, instead of gradual like Luffy's, and that because of his said defeat of a Vice Admiral. He is not a Supernova, but had a similar growth. In essence, it's all about headlines and popularity, not a fighting rank or a political rank (Like Shichibunkai or Yonkou).
