The Smiling Titan in Attack on Titan is Dina Fritz (later Dina Yeager), the first wife of Grisha Yeager and mother of Zeke, a descendant of the royal family. She was transformed into a Pure Titan by Marley as punishment for treason and became infamous for eating Carla Yeager (Eren's mother), which deeply traumatized Eren and fueled his drive for vengeance, making her a key figure in the series' tragic backstory.
Dina's later revealed identity complicates simple moral binaries. Concise summary: The Smiling Titan ate Eren's mother because, as a mindless Titan (Dina Fritz in Titan form), it attacked humans on instinct during the Shiganshina breach; her proximity and Carla's exposed vulnerability made her a target.
The "Smiling Titan" is the unofficial name of Dina's Pure Titan that was notable for killing Eren's mother, Carla Yeager, the new wife of her former husband during the invasion of Wall Maria.
Dina Yeager, known as the "Smiling Titan" and a member of the Fritz royal family, was the first wife of Grisha Yeager and the mother of Zeke Yeager. She was transformed into a Titan and caused the death of Carla Yeager, Eren's mother, traumatizing Eren and driving him to seek revenge.
Eren called pure Titans to eat the Smiling Titan because he needed to eliminate her without being seen doing it himself, and he exploited the Titan shifters' behavior and Paths to achieve that outcome efficiently and secretly.
The Cart Titan is in no way a weak link, but it can be considered the weakest of the Nine. Held by Pieck Finger for the run of the show, the Cart isn't built for direct combat or known for its overpowering strength.

This activates the power of the Founding Titan within Eren, and he seemingly gains control over the surrounding Titans. The ones that are under his control proceed to kill Dina by ripping her to shreds and devouring her, avenging the deaths of Carla and Hannes.
Yelena is a very tall woman with her blonde hair styled in a short bob with straight bangs. She has large black eyes, thick eyelashes and somewhat androgynous features due to her build and style. She also sports a chinstrap beard, which is later revealed to be fake.
Zeke also appeared to share a friendly relationship with his fellow Warriors, though Pieck would later remark on how duplicitous and secretive he always seemed. Ultimately, Eren seems to be the only person he truly cared about, as he feels that they were both victims of their father.
Clash of the Titans arc
Before the Wall Rose invasion, she and the other inhabitants of Ragako village are gassed by a squad of Marleyan soldiers and turned into Pure Titans by Zeke Yeager. Ms. Springer's Titan is deformed, with limbs unable to support her body, leaving her completely immobile.
However, despite knowing the eventual future awaiting the world, and his terror at the vision of Eren enacting the Rumbling, Grisha still decided to give the Attack and Founding Titan to Eren after learning about the death of his second wife Carla, reigniting his hatred for Marley and desire for her to be avenged.
However, Dina could not go back to her human form and Grisha was no longer among the living after the Shiganshina attack. Instead, she could find Grisha's new family, but she could never know it, and Eren did not know it either until much later. In this way, she ended up becoming the Smiling Titan.
Eren killed his mom by directing the Dina Fritz Titan to eat her. In his conversation with Armin in the final episode, Eren reveals that he was involved in the death of his mother. In this conversation, Eren also revealed more about the Founding Titan's powers.
Sergeant Major Gross then injected Dina with the Titan serum, and she was thrown off the borderline wall as Grisha, in horror, watched his wife turn into a Titan. Distraught and helpless to watch Dina wander off after Grice, Gross taunted Grisha by saying that she must have been more attracted to Grice rather than him.
Most believed it was the Farmer as the Military Police stated, meanwhile the other half believed Eren was the father. However, in Chapter 139 the theory was debunked and the Farmer was confirmed the father of Historia's baby.
Ymir is a regular girl who pretended to have royal blood, while Historia actually has royal blood but pretended to be a regular girl.
Yelena's almost as strong as Natasha. And presumably, Yelena just has human training as opposed to Natasha's bootleg super soldier serum. Not to mention, Yelena also has Super-Adaptoid powers from when she was in A.I.M, though IDK if she still has them. If she's still a Super-Adaptoid, she can take on anyone.
While Natasha Romanoff had a romantic connection with Bruce Banner, Yelena Belova has a deep connection and mutual understanding with Robert "Bob" Reynolds. Yelena and Bob form a strong bond, particularly due to their shared experiences with depression and mental health issues. You can see they care for each other.
The vast majority of Titans have a masculine body shape, although all of them lack reproductive organs (they have no need to reproduce since they are humans transformed through injection of Titan serum. The exact composition of Titan serum is unknown, but is said to be Titan spinal fluid.).
The power of the Titans could be transferred to a new host, should the current host be devoured by a Titan. This allowed an ordinary Titan to become human again and possess the power of the Titans, and inherit one or more of the Nine Titans' abilities as well as the memories of the previous inheritors.
Instead of killing him outright, the Female Titan -- Annie -- decides to lift his hood and confirm whether or not he was Eren, as that was her objective. Even after the encounter, the Female Titan decides to not kill Armin.
I think what makes her didn't burst out crying is because she witnessed Eren killed people mercilessly too. She's still in shock. Not to mention that before she beheaded him. She was already crying from the last scene of memory in the path that Eren sent to her.
She was asking about supper or something, then something happened, then she said "meat" and died. If it had been left at her first words then the thing about her last words wouldn't have been a big deal because they were in a sentence and not a word said right before dying.
