Fictional character biography.
Centuries ago, a pacifistic group following their spiritual leader Azar fled Earth to escape its violence. The group established a colony that exists between dimensions called Azarath. In the process of creating their new world, they underwent a ceremony that purged every member of their evil natures. The people of Azarath thought the evil they had expelled would be gone forever, however, they were mistaken. In another dimension, the evil they had purged was summoned by a cult seeking to have a demon mate with one of their female members. Nine months later, Trigon was born. He immediately killed every person around him, including his own mother. He went on to rule the world of his birth by the age of one, and destroyed it when he was six. By the time he was thirty, he ruled over his entire home dimension. 
Trigon later forcefully impregnates Arella, a member of the Church of Blood, a cult that worships him. She is found by an extra-dimensional cult and is brought to Azarath, where she gives birth to Raven. During Raven's upbringing, Trigon is aware of her whereabouts, but rarely intervenes and allows the cult to care for her.
Raven learns of Trigon's intentions to conquer the Earth and vows to stop him; she initially approaches the Justice League, but they refuse her on the advice of Zatanna, who senses her demonic parentage. In desperation, she reforms the Teen Titans to battle Trigon, eventually sealing him in another dimension.
Trigon eventually escapes and comes to Earth, taking control of Raven and destroying Azarath. The Titans attempt to fight Trigon, but are contaminated by his demonic influence and kill Raven. This allowed the souls of Azarath to possess her and use her as a channel to kill Trigon with purifying light. Although Trigon is gone, his followers, led by Brother Blood, have tried to revive him several times.
The Sons of Trigon.
Trigon is later resurrected under unspecified circumstances, but his sons, Jacob, Jared and Jesse, betray him and steal his powers. They corrupt Raven before being defeated by her and the Titans.
"The New 52".
In "The New 52" reboot, Trigon is a minor demon of an unspecified species targeted for extermination by an alien group calling themselves the Divine. They control an entity called the Heart of Darkness which feeds on evil beings, destroying them in the process. However, when it attempts to feed on Trigon, he gains control and manages to absorb all of its power, thus granting him the power to conquer worlds. 
Once he absorbs all the power from the Heart of Darkness, he kills the Divine and attempts to cross over to a new dimension, but is blocked by a lingering spell by the Divine. To circumvent this, he summons a woman from the realm he attempted to cross over to and impregnates her, before sending her back to her home world. Later, she gives birth to Trigon himself, giving him access to her dimension. 
Trigon begins a quest to sire as many children as possible to aid him in his conquests, however, only three boys survive, and he considers them failures. Eventually, he impregnates a woman from Earth named Arella, who gives birth to Raven, finally giving Trigon a child he views as a worthy heir. 
Trigon's only true rival is a woman named Alazandria, who possesses a magical suit of armor known as the Silent Armor that was enchanted specifically to resist Trigon. She battles him to a standstill, but neither are able to kill the other. Her armor is eventually inherited by Wonder Girl.
He has four children: Raven, Belial, Raskoff, and Suge.
Trigon rules six kingdoms known as the Under-Realms, but has grown bored with the responsibility of ruling them, and attempts to pass leadership to Raven. Raven, feeling lonely at the prospect of one day ruling Earth alone, begins to magically spy on the Titans. Trigon allows her to go to Earth to infiltrate the team to learn their secrets before betraying them and conquering Earth. However, Raven ultimately loses the ability to contact Trigon and finds joy in the fact that she no longer has to obey him.
During the "DC Rebirth" event, Trigon is killed by Bizarro, but is eventually resurrected.
