I like Namor but stop hating on Aquaman, he's awesome as well.

" @joshmightbe: Ow sorry, I did not mean you. I should have quoted the person above me ;-) "

I don't think they're rip offs of each other. There's enough differences. I think writers just start running out of superpowers to use. Like Plastic Man/Elongated Man/Mr. Fantastic. I guess what really matters is which character is written better.

" @StrongestOneThereIs: You expect him to be the same as Namor?.. Of course you'll be disappointed then... Unique? magic water hand, hook, control sea life. All things Namor can't or hasn't got. Only thing similar powerwise is that they have super strength (like most of the superheroes), and are sub-mariners (also quite common). "

technically, Atlantis proceeds both.
 
i like Namor alot more, but Aquaman is a fine character.
he just has the downside of being written poorly alot of
the time. He's also dead.
 
i do hear you however about people saying Namor is the rip-off,
when in fact Namor came first. people also say the same about
Namor being a rip-off of Black Adam and theyre wrong as well.
 
Namor = 1939
Aquaman = 1941
Black Adam = 1945

namors wayyyy better
