He grew up as an orphan on Raithal until at the age of 14 when he was taken in by the Sector Ranger Toro Espio and his wife Lira, who was pregnant with their first child at the time. In spite of some early difficulties, and the frequent absence of Toro given his job, his new parents took on the challenge of raising him eagerly. Prok got along quite well with his new younger brother, Raithe.

His adopted parents reinforced Prok's surprisingly strong innate moral compass and when he was old enough, they enrolled him in a police academy on Raithal. With the lessons instilled in him by Toro, he rose to the top of his class and was flagged as a potential Sector Ranger recruit.

After a few years on the job on Raithal, he was recruited to the Sector Rangers and assigned to the Larrin Sector. About the same time as he was promoted, his younger brother Raithe joined the police force on Raithal, and got married shortly thereafter. After some key exploits and the single-handed dismantling of a large-scale terraforming scam on Filordis, Prok was recruited to the SEOs.

After only about a year, he received word that his father had been murdered. He was greatly distressed by this, but in his own investigations in his off-time, he had no more luck than the local authorities and has since given up.

A little over a year ago, he was tasked with breaking up a smuggling ring. His investigation led him to a smuggling run on Arkania. He lay in wait for the ship, a KST-100, and ambushed it. He got off a salvo with the ion cannons before the pilot had time to react, but the ship was resilient enough to shake it off and keep going. As he chased the ship, he began to suspect that the pilot was intentionally letting him stay on the Kestrel's tail. Making a pretty convincing show of running for it, but still allowing him to catch up. He managed to disable the ship, then docked and boarded in deep space. He took the smugglers captive without violence and then through his interrogations of the prisoners, he discovered that the Zeltron pilot had been coerced into the job. She was already wanted in multiple smuggling jobs unconnected from this particular organization, but he sensed an opportunity here. When he went to talk to her, she tried to weasel her way out of it, charm him, or even persuade him with her pheromones, but, aided by his respirator, he kept up his stony exterior. However, he did offer her a chance at redemption: He would secure her a full pardon if she helped him in his investigation to take down the smuggling ring, piloting for him. Until her side of the bargain was fulfilled, her ship would remain impounded and she would be responsible for the storage fees so it wouldn't get auctioned off.

By now, they've been flying together for a while. With her help, Prok was able to bring down the organization. Even though her side of the deal is done, Prok wants to keep her around. She's an excellent pilot, and has shown good progress in turning over a new leaf, but he suspects that if she was cut loose she would likely turn back to smuggling to get her adrenaline fix.
Fortunately, she seems to feel the same about sticking around, possibly, he guesses, because there are still members of the organization who might be out to get her.

Recently, on a whim after processing a recent batch of criminals, Prok decided to check on the status of a Kyuzo he had earlier arrested for sentient trafficking, among other heinous charges. To his consternation, he found that the prisoner was released from the sector prison under mysterious circumstances.

He is capable of making himself understood in basic with the aid of a vocal enhancer integrated in his respirator.
