Rank Titles- Suggestions for Changes?

[Shredder]

Since Krang is planning to update the rank images for the Technodrome soon (which are currently silver stars), I began thinking that it might be a good idea to consider updating the rank titles as well. Right now, we use fairly general terms for ranks (like "Member" and "Advanced Member"), so I was thinking of how we can possibly change this to better reflect the Technodrome's image. I came up with a general list that is very open for suggestions. Since our site is mainly dedicated to the "Technodrome crew" of the original TMNT show, these titles are meant to represent the bad guys rather than the Turtles:

-Villain in Training
-Fighting Robot? (needs better wording, but represents things like Mousers and the various robots the TMNT fought)
-Random Punk
-Foot Soldier
-Stone Warrior
-Hench Mutant
-Alien Mutant
-Mad Scientist
-Rival Ninja (or Foot Clan Ninja)
-Emperor?
-Supreme Ruler? (these last two represent how Shredder and Krang sometimes referred to themselves when they talked about ruling the world, but better suggestions are needed)

We need 11 ranks in all. So...any thoughts on this? Would you rather just keep things as is or does this sound interesting? Thanks for your input!
