Ace and Ymir

The reason behind this, is because when Ymir started getting more screen time in the manga she started to remind me of Ace (not in a 'she's a copy of him' but in a more vague way)

I guess part of it is the physical appearance, but another part I love about them is their mentalities about their lives. Ymir knows that people think that she never should have been 'born' and decides to give the world the middle finger and live for herself (and Christa)
while Ace wanted to know if he ever should have been born, so he spent his life searching for people who would love him/be happy that he was born

Anyway, both of them are flippin' fantastic characters
