Im slowly finding my way through this and have finally found some characters that I like!
With the sidekick & hero I found a character sort of worked for me and them worked on that one.
With the sidekick I quite like 8, 10, 12 as they for me look quite interesting. They have the hole army thing going on while still feeling a little ... sleazy.
For the Hero I quite like 4, 7, 10 as they feel like they could be found in a desert which is where he is meant to be from. I really like 10 but worry its to much? while 4 i like but its just the dead basic version of 7 & 10.
