YMMV, but IMHO these are the richest in comics:
All net worths are estimated.
1. Most Excellent Superbat ($20 Trillion) He bought Japan. 'Nuff said.
2. Victor Von Doom ($15 Trillion) Owns his own country.
3. Scrooge McDuck ($2.8 Trillion) Has a frickin' money bin filled with gold coins!
4. Flintheart Glomgold ($2.79999 Trillion) Scrooge's biggest rival.
5. Richie Rich & The Rich Family ($1.95 Trillion) The world's richest kid.
6. (Tie) Lex Luthor & Bruce Wayne ($850 Billion) Lex because he's recently re-acquired Lexcorp. Bruce, because he's the gosh darn Batman.
8.T'Challa (Black Panther) ($100 Billion) This is before all Wakandan Vibranium became inert.
9. Adrian Veidt ($25 Billion) This man engineered a faux alien invasion to end the cold war. (maybe)
10.Reed Richards ($10 Billion) He has his fingers in a lot of pies, and it takes lots of money to do that.
