Henchmen and Minions ARE different things.
Minions are sorta like mooks. Nameless Peon 1, Nameless Peon 2 etc. When they die, you'll mostly feel sad that the money you spent on them was lost
Henchmen aka Underlings aka Boss Minions are miniature characters. They have skills and abilities. They're superior to minions in every way

I will TRY to tailor them to your character, or at least my perception of your character
