Is there any character that can defeat Eren Yeager? And I'm not talking about Shingeki no Kyojin Eren Yeager. Hell, I'm not even talking about Shingeki no Kyojin Eren Yeager in contact with an Eldian of royal blood, so that he activates his Shiso no Kyojin coordinate powers. I'm NOT talking about Shingeki no Kyojin Eren Yeager after ingesting the Yoroi no Kyojin serum and having practiced his hardening abilities with Hange and the Survey Corps. I couldn't be talking about Shingeki no Kyojin Eren Yaeger using Porco Galliard as a nutcracker to destroy the Sentsui no Kyojin crystal so he can consume Ms. Tybur and gain precise creation abilities. I'm definitely not talking about Shingeki no Kyojin Eren Yaeger with mastery over his Sentsui no Kyojin creation abilities used to break open the Megata no Kyojin crystal and consuming Annie Leonhart in order to gain her titan abilities. I'm really not talking about Shingeki no Kyojin Eren Yeager commanding a group of loyal followers who have dedicated their lives to fulfilling Eren's dream of finally setting his people free and ensuring the safety of generations to come. Do you think I'm talking about Shingeki no Kyojin Eren Yeager after going fully nuclear and telling Mikasa he's hated her his entire life and beating the ♥♥♥♥ out of Armin because they're both just slaves who refuse to accept freedom and try to get in the way of his true, eternal freedom? You better be joking if you think I'm talking about Shingeki no Kyojin Eren Yeager after being ambushed by the surviving members of the Senshi-tai, effectively fighting off both Reiner and Porco at the same time and even taking on Reiner, solo, after eating two direct headshots from an anti-titan sniper rifle. I'm talking about Shingeki no Kyojin Eren Yeager in contact with Sieg's Kemono no Kyojin form, albeit rejecting Sieg's plan to force Eldians into sterility in order to protect his lover, Historia Reiss, so that his child can be born free into this world.

EDIT: This didn't age well
