The villains were generally interesting, Blight for sure (though technically he's more of a Lew Moxon character, since the one who did the killing was Mr Fixx.
Inque was a great villain, though it came as something of a shock to discover she must have been in her late 30's at least since she had a daughter in her late teens.
The sonic powered guy was Shriek, and also worth of mention were Spellbinder, Curare and the hunter guy whose name escapes me.
