on a scale from 1-10 I would say:
Ozymandias 7...he did win, and it was a fun read, and he did kill a large number, he seams to fit the list well
Davros (Doctor Who) 7 again he seams like low end of this list, I mean he really does get shut down and beat alot...
Emperor Palpatine 3 I see this one more of a "writer on your side" victory then any real cleverness or power...I would vote him off the island...
Luca Blight (Suikoden II), Prince of Highland who?
Syndrome, from The Incredibles 3 he seams to be what the op is talking about, outside of his movie is he really a BA???
Kafka who?
Dracula. 8 Major cool points but loses something in the over all too easy/ too many flaws department
Iggwilv, the Witch-Queen who?
Iuz 1 why is he even on this list...
Roy Batty (Bladerunner) 1 see above
Doomsday/Armagedon Beast (Death of superman) 9 he is one of my two, and the one that again wins, and kills an icon, but his brute status does leave him a littl flat
David Xanatos (Gargoyal cartoon) 12 he is evil batman and evil Ironman mixed with sherlock holems...he wis, he only ever sufferes mild setbacks, ow and did I menton he has puck (yea the puck) as a sidekick/lacky
Bill 5 not bad, but the movie again was all him, outside of the setup I am not sure he qualfies...
Voldemort 5 beaten by 'love' and a gang of untrained kids does not endear me to the villain, I mean this story has dues ex written all over it (mind you I liked and own every harry potter book)
Blackie Duquesne who?
Lavos who?
The Joker 10...yea if xanatos and him aren't int he final 4 I will be mad, this guy crippled batgirl, killed a robin, knows Bruce wayne is batman, and is still a crazy SOB who lives in the city with the highest per capita crazy SOBs and is still considered the 'clown prince of crime' and that is just in 1 countinuity... lets not forget just main line DCU he is still a bad ass...
Ursula Disney's the Little Mermaid 8 good solde choice, but I don't see her makeing it...
