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 Shingei 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. I'm talking about Shingeki no Kyojin Eren Yeager in contact with Sieg's Kemono no Kyojin form, activating his Shiso no Kyojin coordinate powers in order to wake up all of the Cho ogata Kyojins within the walls surrounding Shiganshina district and commanding them while Sieg uses his bloodline coordinate power to command the Eldians who drank his spin fluids to aid in the defense of Paradis against the Marleyan army in order to allow Eren to protect his lover, Historia Reiss, and their unborn child.
