Who are the greatest minds of the DC universe?

Let's keep it separate between DC's earth and DC's space. For earth, I would say:

Earth:
1. Alexander Luthor Jr.
2. TO Morrow
3. Lex Luthor
4. Niles Caulder
5. Ray Palmer
6. Ultra Humanite
7. Will Magnus
8. Mr. Terrific/Terry Sloan
9. Prometheus
10. Professor Ivo

Space:
1. Metron
2. Brainiac 5
3. Brainiac
4. Brainiac 3
5. Vril Dox
6. Rip Hunter
7. Captain Comet
8. Epoch
9. Saradath
10. Adam Strange

Alexander Luthor, Jr. would count more as a "cosmic" character than an Earthbound one, imo.

Lord Havok.

I was going to put him in the alternate earth/cosmic tier, but when he go resurrected by Tangent Green Lantern, I think he stayed on earth. Right before the DCnU relaunch.

Does Metron really count?

Why wouldn't he?

He has omnipotence

When was this stated?

It's pretty heavily implied he freely travels through time and space

I don't think I have ever heard anyone say Metron is omnipotent. But I haven't read every appearance. Orion can travel between time and space, yet he isn't omnipotent.

Metron does not possess omnipotence or omniscience. He has proven himself quite fallible on several occasions.

Would you rank his intelligence ahead of Brainiac/Brainiac 5?

Oh yes. By far.

/shrug

On Earth: Lex and Ivo.

In space: Metron and Brainiac 5.

Toyman should be on the list.

And honestly so should batman. Now before you cry fanboy let me explain. He's a jack of all trades and is and expert in many different fields. He's a prep genius, and his mind is evidently of the greatest in DC.
