Beloved Tomboyish Daughter
Cirno is the strongest, what more do you need to know? She freezes frogs and doesn't afraid of anything.
Even besides the memes, Cirno remains enduringly popular because she's just so cool (pun intended). She's got a simple design and neat ice-crystal wings, with a big personality. I know everyone calls her a baka, but I think it's great how she doesn't let that faze her.
Also, she's got a nice Sp. Atk stat, and the surprisingly rare Ice typing. Plus she's cute as a button.
Overall: 9/10 10/10
