Super Rookie

Super Rookies (超新星（スーパールーキー）) refer to any rookie pirates who managed bounties of over 100,000,000.

Overview
A pirate's impressiveness and first-impression strength is usually dictated by the bounty he or she earns. Therefore, the higher the number, the more fame and respect the said pirates receive. Any rookie pirates who manage to receive a bounty of over 100,000,000 before they enter the New World is considered to be impressive, as it marks that said rookie has committed criminal acts of catastrophic degrees. However, once past the "Paradise" half of the Grand Line, bounties of around 100,000,000 are considered common and even weak.

While bounties of 300,000,000 is highly impressive, it is still considered a rookie. However, if one exceeds that amount to about 400,000,000, one is no longer considered to be a rookie, but instead as an elite.

Five Years Ago
Five years ago, Portgas D. Ace began his life as a captain of the Spade Pirates, and later gained the title of Super Rookie.

Three Years Ago
Three years ago, Cavendish gained a high reputation among the rookies, but the one year later Worst Generation's arrival overshadowed him.

Two Years Ago
Two years before the current storyline, eleven Super Rookies arrived at Sabaody Archipelago almost simultaneously. Collectively, they are known as the "Eleven Supernovas" (11人の超新星). These eleven, alongside Marshall D. Teach, were considered to be the Worst Generation (最悪の世代) to ever come to existence, due to their individual actions bringing great (or terrible) changes to the world, leaving deep and lasting impacts.

One Year Ago
One year after the Worst Generation's rise, at least another Super Rookie earned his fame: Bartolomeo the Cannibal.

Current
In the current timeline, came at least two more: Caribou and his brother Coribou. Though both respective rises were impressive on their own rights, neither year were comparable to the Worst Generation.

Trivia

 * The first half of One Piece is known as Sea of Survival: Super Rookies Saga.
 * Bellamy once held a similar title: he was known as the "Big-Time Rookie" (大型ルーキー), due to his bounty being at a moderately high 55,000,000, something his crew and Mock Town found impressive and noteworthy.
 * It should be noted that after the two-years timeskip, his bounty indeed went over 100,000,000. However, by that time, it is unknown if he is still considered a rookie.
