She's 5'11 with blonde hair and blue eyes, she has superhuman strength, speed, durability, agility, reflexes and she can lift up to 100 tons underwater (75 tons on dry land).
What's not to love?
Namora has got the jump on DC's Mera by quite a bit considering that she was created by writer Ken Bald and artist Syd Shores way back in 1947. So she had a sixteen year jump on Mera.
And if you are like me you probably went, "Namora? Really? Why didn't they just call her Sub-Mariner Girl?" Well actually, her name as created was Aquaria Nautica Neptunia which allowed the writer to use all the Latin sounding underwatery terms he could think of. She took the name "Namora" to honor her cousin Namor. Namor (in Atlantean) means "Avenging Son" and Namora means "Avenging Daughter"...so it's not as bad as it sounds. In comic book terms at least.
Namora has your basic butt-kicking Atlantean abilities. She is five foot eleven, 189 pounds and has blonde hair and blue eyes. Namora has super-strength, limited invulnerability, she can swim at superhuman speeds, and she has those little wings things on her ankles that allow her to fly like Namor.
Side Note: No she doesn’t. Those little hummingbird wings on her feet are not gonna make her fly! Sorry...they may have bought that in the 40s....but no. She has to have some kind of psionic ability.
Anyway... besides all those powers...it's possible she has an even worse attitude than Namor when she gets angry. So that makes her pretty rough in a fight.
