and regular non powered folks also. Though no reason they can't be comedic villians. Or do some tweaks.
There is no reason instead of being the big bad, they can't work for a big bad and be what my friend would call named thugs. These are a type of bad guys who are not the main bad guy, they work for the big bad and are not eliminated quickly like unnamed thugs are, at least not till near the end of the rp or story. They can be beaten but escape or send in unnamed thugs and escape when they see their unnamed thugs being easily beaten, often in large numbers in some fiction.
You can also have named thugs be minor and major named thugs with minor named thugs while being dangerous opponents do not last anywhere to near the end of the rp or story, like Boba Fett and his father. Unlike say Darth Maul, Count Dooku and Vader. Though perhaps not good examples.
