Lucan (Image Comics: Invincible)

History
Lucan was one of three warriors of Viltrumite who appeared in the skies above Thraxxa when Omni-Man first attempted to flee the Viltrumite Empire. Lucan and his allies destroyed the people of Thraxxa, causing their kind of near extinction before Omni-man came out of hiding and met them in the skies above the capital.

While Omni-man was fighting his mates, Lucan accidentally followed Nolan's son, Invincible, to a mass of dark caves which he had hoped would hide from his location.

Lucan challenged Invincible in the woods, but when he found Nolan's other offspring within them, he was shocked into quietness. His shock lasted long enough for Invincible to trick him and escape from the caves.

Angry at his own dumbness, Lucan pursued Invincible in a blaze of motion. He'd almost seen him in Thraxxa's open skies. When he closed between them the last few inches, Nolan crashed into the small of his back and drove him down into the ground.

The Viltrumite War
During Viltrumite War Lucan was next seen. He was one of the three Viltrumites that were sent when they first entered Viltrumite space to confront the Grayson family. Lucan ended up fighting both Omni-man and his son Oliver, while Conquest struck a standstill against Invincible.

Lucan did everything he could to defeat the two. But in the end he let them escape to turn his attention to their other allies.

Lucan also took part in the final battle over Viltrum, during the war. He was one of the many Viltrumites who ended up so severely wounding Allen the Alien that he was forced to quit the fight

Colonizing the Earth
At the end of the battle, Lucan joined the remaining Viltrumites in colonizing the Earth. He was given strict orders for impregnating as many human women as possible in efforts to improve the flagging numbers of the Viltrumites. But instead Lucan decided to remain tragic to one of the human beings with whom he fell in love.

He was waiting for retribution for his direct defiance of Thragg's orders when it was discovered that Nolan was the Viltrumite Empire's true ruler. He (with General Kregg, Anissa, and Thula) stopped Thragg from assassinating Nolan outright. They nearly beat him to death until he was forced to be allowed to live by Nolan.

Lucan is at least outwardly loyal to Nolan at this time, serving him as loyally as Thragg did before him.

Trivia
- He has a wife named Miranda, a son, a daughter named Alicia, and an unborn baby.
