Ego

"After all these years I found you." "And who the hell are you?" "I figured my rugged good looks would make that obvious. My name is Ego, and I'm your dad, Peter."

- Ego and Peter Quill

Ego is a Celestial and the father of Star-Lord, who, despite what he had seemed is truly a ruthless and terrifyingly evil monster who desired to conquer the universe for his own pleasure. He is a mysterious adventurer from far parts of the galaxy who has heard the legend of the Guardians of the Galaxy following the Battle of Xandar and has come to meet them for the first time.

Reunited with his son in 2014, Ego desired to forward his plan to rule the universe by using his son's Celestial genes to terraform the planets he has planted alien seedlings on. Ego's victory was seized by the Guardians of the Galaxy and was ultimately destroyed at their hand.

Apparition in the Galaxy
Millions of years ago, Ego was born as a member of a primordial god-like race known as the Celestials. Unlike the vast majority of his species, Ego appeared in the space in the form of a giant brain who didn't know what he was and how he came to be. He discovered his ability to manipulate matter and constructed a shell around himself, which became a planet. After he began to think about the purpose of his existence, Ego decided to create an avatar to explore the galaxy.

Dividing and Conquering
As time progressed and as Ego had became one of the last few of his species, he began a desire to conquer the universe for himself. He tried to achieve this feat by planting extraterrestrial seedlings across different planets in the cosmos. He, in the guise of an individual of the home species of the planets he had encountered across the universe had conceived multiple children in an attempt to terraform the planets and interlink them to his own body, as the mechanism required to activate the seedlings required two individuals with the Celestial gene. When his children had failed to inherit his Celestial DNA, Ego had them and the woman he had impregnated with over the millenia murdered.

Experiences on Earth
"You’re so like your daddy, you even look like him. And he was an angel, composed out of pure light..."

- Meredith Quill to Peter Quill

In 1980, he visited Earth to plant one of his seeds in the woods of Missouri, United States. He met human Meredith Quill and awed her almost instantly, under the guise of a "spaceman". Ego and Meredith had conceived a child named Peter Quill, who would later go on to inherit Ego's Celestial DNA, becoming the first successful offspring of Ego's to do so. When Ego learned that he had felt true love for Meredith and that it would put him off-task to stay on Earth, instead of forwarding his plans to conquer the galaxy, he deliberately triggered a inside Meredith's genes, leading to her death in 1988, before leaving Earth. Meredith described him to her son as an "angel," and a being of pure light, which her family seemed to regard as a delusion.

In the weeks leading up to Meredith's death, Ego had hired the Ravagers led by Yondu Udonta to bring his son to him. Udonta, though, remembered him as a jackass, (later on, it was proven he was right about Ego's true colors). However, Yondu trained Peter Quill to be a Ravager as his protégé instead of delivering him to Ego. In between Meredith's death and the Quest for the Orb, Ego took up a new protégé, Mantis and the two had resided on Ego's planetary form. After the Battle of Xandar, the Nova Corps did an analysis of Peter Quill. Irani Rael commented that Quill's father was something "they had never seen before."

Meeting the Guardians
When Ayesha had sent her fleet of drones on the Guardians of the Galaxy team following the reason Rocket Raccoon had stolen their batteries after defeating the Abilisk, Ego appeared and destroyed the fleet while the Guardians crashed on a nearby planet, which is Ego's. On the planet, Ego met with the Guardians and revealed himself as Quill's father. During the meeting, Ego attempted to make Quill to return to his home accompanied by Gamora and Drax while Rocket and Groot guarded on Nebula.

When Yondu Udonta and the Ravagers arrived to capture Quill and to hand him over the Sovereign after being hired by Ayesha, Nebula tricked Groot to free her, while Taserface carries out the mutiny against Yondu and executes his loyalists with the help of Nebula, who leaves to kill her sister as revenge for being installed with cybernetic and robotic body parts by their father Thanos.

Yondu, Rocket and Groot are taken as hostages by Taserface and his men, while Drax, Quill and Gamora are still meet with Mantis, Ego's assistant which he raised. Nebula arrives on Ego's planet and attempts to kill Gamora, who survives and defeats her sister via a blaster gun, however, she is reaching to an uneasy alliance point, and the two are exploring the planet. Gamora and Nebula are discovering thousands of skeleton remains hidden inside the caves of Ego's planet, and feeling that Ego is hiding a secret from them.

True Colours Revealed
"You killed my mom! And squished my !"

- Peter Quill While still meeting with Quill and Drax, Ego explains that he is one of the god-like Celestials, and exists in the form of the planet on which they are standing. He assumed a human guise to travel the universe and interact with other species, eventually meeting and falling in love with Quill's mother Meredith. After Meredith's death, Ego paid Yondu to collect the young Quill, but Yondu never delivered the boy, and Ego had been searching for his son ever since.

He teaches Quill to manipulate the Celestial power within the planet. Ego reveals to Quill that in his travels to thousands of worlds, he planted seedlings upon thousands capable of terraforming them into new extensions of himself, but they could only be activated by the power of a second Celestial. To that end, he impregnated hundreds of women and hired Yondu to collect the children; they all failed to access the Celestial power, so Ego killed them, until he found Quill.

Ego uses Quill to activate the seedlings, which begin to consume every world. Quill is hypnotized into helping Ego, but fights back after Ego reveals that he deliberately caused Meredith's death.

Battle on Ego's Planet
"I'm a god. If you kill me, you will be as insignificant as the others."

- Ego's last words Mantis then warns Drax, Gamora, and Nebula of Ego's plan just as Rocket, Yondu, Groot, and Kraglin arrive. The reunited Guardians reach the core of the planet, where Ego's brain is housed, and fight the Sovereign's arriving drones as well as Ego himself. Rocket makes a bomb out of the stolen Anulax Batteries that Groot plants in Ego's brain, while Quill battles Ego with his newfound Celestial powers to allow the other Guardians to escape.

The bomb explodes, killing Ego and causing the planet to disintegrate. Yondu sacrifices himself to save Quill, who comes to realize that Yondu did not deliver him to Ego in order to to spare him from the fate of Ego's other progeny, and that Yondu was Quill's true "daddy".

Personality
When he first meets the Guardians, he seems to be a very lovely, caring and charming being. However, this is only his own cover for his true colors; an extremely powerful, terrifying, manipulative, megalomaniacal, ruthless, destructive, murderous, dark and cold being obsessed with the goal of conquering the universe via his seedlings.

He also cares less about his children and all the woman he has impregnated since all of them are just tools for him to expand his own extensions into the galaxy. His ruthlessness also extends to the fact he is willing to kill any individual, no matter what the cost, whether it be his own children if they fail to inherit his Celestial power as well, or the impregnated women after they had given birth to his children or even the lifeforms inhabiting the planets he desires to control.

After I had worked out a very elaborate story with Ego the Living Planet as a very important part of the Marvel cosmic universe, I learned that we actually didn't own the character.
