SciFi Server Rank Names

[Spenser]

I am helping someone work on a SciFi themed server , what are some cool rank names? I need like 5/6

 

[Spenser]

Surgeon, Dentist, Doctor, Scientist, Biologist

Those are science not science fiction , like for star wars or star trek themes

(default rank) - Alien - Hunter - Angel - Overlord - Zodiac
goes in order of price, Alien - cheapest, Zodiac - highest
