I've never seen her in any top lists, but personally I would choose Vanessa from KoF. 

Yup

Sidon. Everyone likes best fish waifu, right ?!

Tharja from Fire Emblem Awakening. I love how strong, dark and dedicated she is. Her design is icing on the cake.

I also like Twintelle because how strong she is as well... but i'd be lying if I said the main reason wasn't because of how THICC she is. I do wish they showed off her muscles more though, I would've liked to see her abs but oh well.

This one might make me look weird but here goes...

Mipha from Breath of the Wild. I know she's a fishlady but goddamn do I love her! She's gentle, sweet and willing to fight for those that she loves. 

Also I think she's cute...

I have more but those are stand out ones I guess.

Wow, this is... some list.

Narmaya is cute. So many mobile game waifus.

Cherche

Mythra/Hikari from Xenoblade Chronicles 2 is my pick. I rarely ever swapped her out of my party because I hated not being able to see her while exploring. You wouldn't believe how many screenshots I've taken. Here's some fanart I like though.

I see she's got a plumber's crack

I see some of you have my favorites so I'll add a character not mentioned.

Aqua from Kingdom Hearts.

Pardon me for the pic size.

Love me some aqua. If a mod is reading this, could you do me a favor and post a pic of millia rage from guilty gear xrd? She’s my choice but I don’t know how or can’t post a pic using my iPhone. 

Edited...have to support men of culture after all

Awesome! Thanks super!! :)
