We first learn about Polaris in Deceiver: Revenge Time.

Polaris was a hidden apprentice of the Overlord. During Season 3, he helped the Digital Overlord regain his form in secret from everyone, that's when they met. Polaris demanded to be made his apprentice, his successor after Ovelord took over. Ovelord agreed and began teaching him the secrets of dark magic, the history of dark power. So much so, that at first Ovelord thought of getting rid of Polaris later on, but in time he discovered how this Chumsworth was eager for knowledge, determined, cunning, and actually began to treat him as his faithful apprentice, as a result of which he transferred some of his form/dark power to his heart, which made Polaris an even greater villain than at the beginning, heartless and unscrupulous, determined to kill, eat people and harm children without hesitation.

After Ovelord's final defeat, when he was defeated by (YN) in Knighton, Polaris sought revenge. He wanted to avenge his former master and make those who defeated him pay severely for their actions. This also involved the hunt for Pythor, who, during Season 4, abandoned the path of evil and is on ninja side.

Polaris during and after the Serpentine War:

As the son of a Great General, he had a high status in the Anacondrai Army. He was one of the captains/commanders and had his own brigade.... The Shadow Brigade. His unit was tasked with eliminating villages that posed a potential threat to the army, and he destroyed them, set fire to them, and with particular cruelty murdered men and residents who failed to escape. He then ordered the soldiers to rob the houses of weapons and valuables. He hated humans. Simply put. He also hated and severely punished his soldiers for showing mercy to humans. Once someone defied Polaris' order and was killed by him for treason.

After the war, his psychic was affected by the fact that his people started.... well, they started eating each other and committing suicide. Unfortunately, he, Cyrus and Pythor were forced to cannibalize their loved ones, which took more of a toll on his hatred of humans for condemning them to such suffering. So he never wanted to die, he wanted to gain knowledge on how to become immortal, to have an indestructible army not susceptible to death.

That's why he decided, since the Overlord didn't give him what he expected, to ally with the Queen of Nightmares, the necromancer, Nerath and her army of undead. She gave him what he wanted: indestructibility. She transformed him into the monster he was in his heart from the very beginning. His true form. He changed his name to Basilisk.

He hates... more, he is ready to kill whoever compares him to his brother Pythor or Cyrus. According to him, he has no family, never had family.

If I could point out who he resembles in character. He's like a combination of Scar from The Lion King and William Afton from FNAF, the worst villains combined into one, creating a dangerous mix.

Polaris never had a good nature. He only showed appearances, even in front of his father General Arcturus. 

Relationships with characters:

Overlord - former master

Nerath - master, ruler. It can be said that in Ninjago: The Descendants of Elements they may have shared an unhealthy fascination. Polaris in spite of the fact that his heart was not made for love, he greatly admires his ruler and gives her his loyalty for making him powerful. Since he learned of the legend of the Queen of Nightmares' tragic story he has found his reflection in her, both of them have been hurt very badly by fate and this may be the reason of their connection. Both have an obsessive, great lust for revenge.
