During the Titan attack on Wall Maria, many human-eating humanoids invaded the town Eren and his family lived in, and one of the Titans was Dina Yeager, the smiling Titan who later turned out to be Grisha Yeager's first wife. She was responsible for the death of Eren's mother, Carla.
She was caught for treason against Marley and was turned into the Abnormal Titan that would later eat her husband's second wife, Carla Jaeger.
Activating the Coordinate ability, a power that he did not know that he had, Eren seemingly started to gain control over the surrounding Titans and they proceeded to kill the Smiling Titan.
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.
As Armin tries to rescue Eren, the Bearded Titan closes its mouth, biting one of Eren's arms off in the process, and swallows Eren, much to Armin's hysterical horror. It is unknown how Armin survived the Bearded Titan and the others afterwards, but he was no longer attacked after the deaths of his friends.
Eren proved his love for Mikasa before the two of them really knew each other. When Eren and his father managed to track down the men who'd kidnapped and murdered Mikasa's family, he didn't hesitate to save the day.
And the idea of Levi hating Eren, well, that is not so evident— but with some analysis, one can speculate that he "disliked" Eren at best, due to his initial suspicion of him. Levi has also called Eren a monster on multiple occasions due to his uncontrollable nature and strength.
Founding Titan
Founding Titan is the first and the strongest Titan of all the nine. If the Founding Titan is someone from Royal Bloodline, then it will possess limitless power. Eren Yeager was not someone of royal blood that's why he asked for Zeke's help to use the Founding Titan to its fullest.
Eren Yeager and Mikasa Ackerman are two of the main characters in Attack on Titan. The two have been together since the very first episode of the series.

The protagonist of the story, that resorted to mass genocide to protect the things he loves, is at the top of the list. Before he decided to do that, he had been killing titans as a titan shifter of the Attack Titan.
4) Eren strikes down Colossal Titan
Episode 17 from Season 3 of Attack on Titan sees Eren fulfilling his promise of avenging the fall of Shiganshina through his act of defeating the Colossal titan. With the help of Armin, he brought the said titan to its knees in the most vicious manner.
He is brutally damaged and knocked down to the ground. After witnessing the tragedy of Falco turning into a Titan at the sound of Zeke's scream, Reiner stays put as Titan form Falco attacks the nape of his neck.

10 Kitz Tried To Kill Eren When He Found Out He Was A Titan
However, other people were scared of him and thought he was a threat, such as Kitz, a captain of the Garrison. He ordered his soldiers to kill Eren, along with Armin and Mikasa for trying to protect him. Luckily, he was stopped by Commander Pixis.
Historia fell pregnant before Eren left Marley and his home was not far from her. Floch was entrusted to guard Historia. By telling Floch and Historia his plans, Eren was able to spread word of his intentions. By impregnating Historia, he would protect her and eradicate the Curse of Ymir.

In the popular parody series A Slap on Titan by Tom Andre, Armin falls in love with Annie and describes himself as the 'Crimson King' and Annie as his 'Dark Queen'.
Pieck's Cart Titan is arguably the weakest of the Nine, but it comes with several advantages. Unlike its eight brethren, the Cart Titan walks on all four legs, making it an excellent method of transport. Pieck often has large structures attached to her back, which carry both people and weapons.
The nine Titan powers were the Founding Titan, the Armored Titan, the Attack Titan, the Beast Titan, the Cart Titan, the Colossus Titan, the Female Titan, the Jaw Titan and the War Hammer Titan.
When it comes to pure skill, Levi far outranks Eren. Not only does Levi have more experience in the field, but he's also just a better fighter overall. Without his ability to transform into a Titan on command, Eren wouldn't stand a chance against Levi.
2 Captain Levi Ackerman Boasts Of 58+ Titan Kills (And More Than A Dozen People)
In the case of Mikasa and Levi, they share the surname Ackerman. While there's no way they are siblings— they have different parents, after all— there's evidence that the two of them are distant cousins, especially when considering the power they share with Kenny.
In a rare showing of compassion, Kenny decided to take care of him. He raised Levi as well as he could: teaching him knife skills, how to get along with people, and violent behavior.
