Superman villains and the biggest treat to him?

I like watching superman but my questions is what are the names of all the superman villains.Howe is the biggest treat to supermanSuperman villains and the biggest treat to him?I agree with Mike but Doomsday is the one that actually killed him so I would say he's the biggest threatSuperman villains and the biggest treat to him?hes got quite a lot of foes. theres:



Lex Luthor

Toyman

Parasite

Braniac

Darkseid

Doomsday

Livewire

Prankster

Mxyptlk (or mr. Mxy)

Metallo

Bizzaro



There are probably a few more I forgot to list but these seem to be the most popular ones.



Biggest threat? Id say its between Luthor and Darkseid.Superman villains and the biggest treat to him?Mongul, Cyborg Superman (Hank Henshaw)







as to threats Darkseid and Doomsday have to at the top.



Darkseid is an alien god, to his people at least, and has more than once beat Supes like a rented mule



Doomsday has actually killed Big Blue, and can't be taken out the same way twice, meaning Superman has to think (not his strong suit) about what to do rather than just 'hit him harder', which is his usual MO, and often quite effective on any other villain
