Attack on Titan belongs to Hajime Isayama. This blog will discuss the events of Attack on Titan season to season and the character development of Eren Jaeger from a kind of stereotypical anime character to an absolute badass. I will basically discuss important events in the episodes and conclude how they developed Eren’s character slowly but surely.
Season 1 Part 1
During the first few episodes/chapters of Attack On Titan, we saw several things such as Eren’s weird dream(foreshadowing), the mysterious basement of Grisha Jaeger (Eren’s Father), to the breakthrough of Wall Maria executed by the Colossal Titan and Armored Titan, the fall of Shiganshina District and most importantly the death of Eren’s mother (Carla Jaeger) by the ‘Smiling Titan.’ Before all this, Eren was already very enthusiastic about joining the Survey Corps, But he was never supported by his family as they were concerned about him.
Even though Eren(Biological Son of Grisha Jaeger) and Mikasa(Adopted by Grisha Jaeger) escaped the ‘Smiling Titan’ with the help of Mr. Hannes, it traumatized them and also made Eren swear to get revenge on the titans by killing every single titan in the world, and he somehow got the key to his basement(will explain later) while Mikasa and Armin(Eren and Mikasa’s Best friend) were still trying to process everything.
During these episodes, we saw how Eren, someone who was impulsive, cared for his friends even if it risks him getting hurt getting completely filled with revenge for the titans, which leads to him making rash decisions in the future episodes/chapters.
Skipping a few years, We see the 104th cadet corps introducing themselves from bald boi(Connie Springer), Horse boi(Jean Kirstein), Potato girl(Sasha Braus), Armin Arlert, Mikasa Ackerman, Eren Jaeger, and many more.
During the training, we see as Eren is noticed not to be exceptionally gifted(except hand to hand combat) but is still comfortable with ODM(Omni Directional Maneuver Gear) while Mikasa is exceptionally gifted, as we saw during the tests, and Armin is basically the same as Eren except the hand to hand combat part(If you have watched season 4, you know exactly what I mean).
We see Eren telling everybody his story from that day in the cafeteria, which strokes fear into people from fighting the titan's head-on people which soon turned into a fight between Eren and Jean which was stopped by Mikasa.
Their years of training had been finished, and they were now, in the words of Keith Sadis, Cannon fodder.
We saw our main crew on the wall just chatting for banter while Eren thought that the cold finally fight back with their years of training, but, suddenly, out of seemingly nowhere, the Colossal Titan appeared and kicked the Wall with its toes (damn, that would hurt) which allowed several mindless and abnormal titans to appear and start wreaking havoc. While everyone went off to fight the mindless Titans, Eren went towards the Colossal Titan to end him while he went for the nape but could not do it due to the Colossal Titan’s immense heat and pressure, and then in a smoke cloud, The Colossal Titan Vanished in seemingly thin air.
When he reunited with everyone to discuss plans, he wanted Mikasa to stay back as he did not want her in danger, but she declined continuously, so he had to give in. When they arrived to fight, they got decimated, and Eren got clouded in revenge and had his leg bit off by an abnormal.
Armin was about to get eaten as well, but there came Eren to save him as he got eaten instead as already explained, he would be willing to sacrifice his life to save his comrades, so, he got eaten by the ‘Santa Titan.’
Armin soon informed his comrades about Eren’s death, including Mikasa, who started making rash decisions herself as Eren was the one who saved her from the people who killed her parents and also prevented her from getting sold and also treated her nicely after said incident, he was her best friend(or maybe more)and was about to get eaten by titan herself but was soon saved by a Titan(We all know it’s Eren). Eren started to fight all the titans until his body was exhausted, and he was revealed to be alive.
Instead of everyone being happy, Most were confused because a human who could transform into a titan was no daily occurrence, and some felt scared. When the military found out about this, they tried o kill Eren and Mikasa and Armin as they wanted to talk it out, but Eren subconsciously transformed into a skeleton of his titan, striking fear into everyone present there.
As they were about to shoot another cannon, Commander Pyxis stopped the cannons and went on to tell them how Eren could be their greatest weapon and then started to formulate a plan to plug up the hole made by the Colossal Titan with a boulder. The boulder was then chosen by Armin, who had seen it before and estimated it to be the same size as the hole, therefore, plugging it up.
All of this was then announced. The rest of the military forces presented there and were given a choice to run away as the added risk was people also had to get rid of the tians from Eren’s path while he plugs up the hole in the wall. Some soldiers retreated, but the operation was done nonetheless.
The plan commenced, People started clearing out the titans using ODM gear, and Eren, Mikasa, and a few filler characters made their way to the boulder. When Eren transformed, something weird happened; he looked towards Mikasa and started attacking her as he could not control his titan form. Mikasa gained a small scar on her cheeks but did not fight back as she knew Eren from childhood. Eren then accidentally knocked himself out. After that, when all hope was about to be lost, Annie pointed at Eren in his titan form carrying a huge boulder, and the plan re-commenced, and when Eren reached the wall, he plugged up the hole in the wall, and then, humanity had their first-ever victory against the titans.

During these episodes, we saw how Eren, who was an altruistic boy, who wanted to protect everyone he loved from titans, had many things taken away from him; He lost his home, He did not know where his father was, and most importantly, how helpless he was as he could not even protect his own mother from getting eaten. He got completely clouded from revenge, and even he could not see his own rash decisions. Even when he was eaten by the titan while he had been training for years, he was helpless once again, but after he discovered his powers, he felt real hope that he could protect everyone he cares for.
