Eren Yeager [Pre-insanity] (Attack on Titan)

VS

Esdeath (Akame Ga Kill)

Reason: Arguably the two most tenacious members of their Empires militaries. Like I said above, this would be Eren before he went bat-sh*t crazy, but is still able to use the Attack Titan and Attack Titan only. Now, whether or not he can win against Esdeath is debatable, but I really hope he would win because f*ck Esdeath. Also... I'm not afraid to admit that I actually liked Eren before he went nuts. Now, I'm fully that Post-crazy Eren would absolutely slap Esdeath's sh*t. I honestly think that pre-insanity Eren fighting Esdeath would be more of a spectacle.
