Here, we can talk about what characters to use in this universe. OCs are also welcome.

I'd imagine Capper Dapperpaws could be a guy Spike goes to at a secure location to exchange information on what's going on in the criminal underworld.

When Dragon returns, the task force is reformed but the CPD is stretched thin due to the ongoing gang wars and is a lot smaller this time around. However, they were able to enlist members from both the Interpol and the FBI for help.

They are:

Ember Dragoknight: A young inspector from Interpol who has joined the task force to help track down Dragon. She joined Interpol to hope find the master criminal who took her father's life. Dragon contsantly flirts with her which bugs her to no end.

Fleur de Lis: A constable from Interpol and Ember's partner. She isnt as black & white as Ember and Iron Will and knows that the Dragon, while a thief, is a good person at heart and would be more than willing let him go. In exchange for a favor of course.

Moondancer: An up and rising star from the FBI. She knew both Twilight and Spike when they were kids. Like Fleur, she knows Dragon isn't a bad person. Her hacking skills rivals Luna's.

Scorpan: A semi-retired "treasure hunter" who was the partner of Spike's father as well as one of the boy's mentors. He's rather laid back and often takes Spike on one of his adventures from time to time. He and Starswirl do not see eye to eye, especially when it comes to Spike with the latter feeling that he should uphold his duty as Dragon while the former believes he should make his own choices and forge his own path.

I figured Scorpan would be somewhat of a fun loving uncle figure for Spike as well as a foil for Starswirl.

Somnambula Cleopatrot: A rather beautiful who the closest thing Spike had to a mother-figure after the death of his actual one. She moved back into Lupine manor shortly after Spike returned to Canterlot so she could aid him in his mission to take down the crime lords and restore order to the city. She was also the one who taught Spike on how to "please a lady" and gave him his very first kiss, as well as his first time. She would often put Celestia, Luna, and Cadance, as well as the Sweeties, through some rigorous tests to see if they are truly worthy of Spike's affection. Like Scorpan, she too often buttheads with Starswirl and feels Spike should make his choices.

Princess Amira: A princess who hails from a small kingdom in Suadi Arabia. Amira first met Spike two years prior to the first story when the young thief went to the country when he found out one of the heirlooms was within her family palace walls. However, both of them soon discover that Rafaj, the treacherous advisor to Amira's father, plans too not only take over all of Arabia but the entire Middle East as well with the aid of the mysterious Raven Corporation. During this time, the two began to bond and after foiling Rafaj's schemes, Spike and Amira shared a long, passionate night before the young thief left with the heirloom. Amira would soon miss Spike and desires his company more often than not before deciding to run away to be reunited with him again. Spike would run into her when he returns to Canterlot, much to his surprise, and she decides to aid him in his mission to take the crime lords down.
