This week, we celebrate the 50th anniversary of the original Star Trek TV series. To do so, we thought it might be a good time to rank all of the Star Trek crew members. Before we do, a few stipulations:

1: Only Starfleet personnel and related enlisted crews have been considered for placement on this list. (Which means that characters such as Quark, Morn, or, let's be honest, half of Deep Space Nine are absent.) Placement on the list is the result of long consideration of characters' service to Starfleet and/or Starfleet-related causes as shown or implied during their appearances, with one exception that shall not be discussed further. (Good luck figuring out which one is placed specifically due to personal bias.)

2: Only original on-screen media was considered during deliberation. If spin-off material such as novels and comic books had been included, both Captain Clark Terrell and Commander Elizabeth Shelby would be considerably higher up in the ranking. (Star Trek: Vanguard and Star Trek: New Frontier FTW, as the famous 24th century saying goes.)

3: Your argument is invalid.
