Draco
Draco is an extraterrestrial being. His race is generally humanoid with a reptilian appearance (scaly skin like a snake, nictitating eyelids, no nose, lip-less mouth). He described his race as "The Mercenaries" because much of his language doesn't translate well or meaningfully into English, so he was forced to find terms from our language and pop culture to try and get his point across. By this we can infer that his people are do-gooders for hire, employed frequently in a multi-species resistance against the onslaught of the Collective.
From Earth, Draco's home system lies in a straight line many thousands of light years past the constellation Draco, hence his name. His own name was another of those Draconian words that didn't translate well, which was why he tried to introduce himself first as Han Solo and then as James Tiberius Kirk.
Notable features
Draconians are extremely patient and long-lived. They can set a plan in motion and nurture it for years, ever so subtly monitoring and waiting for the perfect opportunity to strike. They play the long game extremely well.
Draco's Plan
Through his own intelligence gathering, Draco learned that the Collective was slowly developing a superweapon program to more rapidly and safely conquer and subvert entire worlds. Their standard method involved years of secretly monitoring a new world, surgically altering their own spies and inserting them into the target planet's population, then using psionic powers to slowly control the minds of an influential few, allowing more troops to make planetfall and wage a war to conquer the entire population. The Collective's new superweapon program aimed to hit an entire world with an amplified psionic surge that would instantly put every mind on a planet in line.
Draco plotted for decades on how to steal the device and the Collective's research on it, putting them back at square one. He knew they would strike back for the theft, so he had to have a safe fall-back position. Roughly a century ago, he sent many of his crew to a star on the other side of the galaxy that long-range scans indicated had a habitable world with all the resources they would need to build an industrial base. This world was so far away that it would take months, if not years, for the Collective to follow him there, and by that time, his subordinates would have had decades to build a defensive position and ships that he could immediately use to strike back at the heart of the Collective using alterations he had made to their own weapon.
Unforseen Complications
A flaw in Draco's plan arose when he finally made it to Earth (the world he'd selected from the long-range scans) with the Collective's superweapon. His people were nowhere to be found, and the planet was inexplicably populated by roughly seven billion sentient beings. Draco's worldview obviously saw the incidence of sentient life as a relative rarity because this possibility had not even registered as being even remotely likely. What he did know, however, was that the Collective was following him here, and when they saw what awaited them on Earth, they would not be able to pass humanity up for conquest.
In the face of this, Draco was compelled to aid humanity in their fight against the Collective. He met with a small group of civilians and shared his technology with them, hoping it would be enough to get the ball rolling and allow them to fight back. Meanwhile, he left Earth on a probable suicide mission to deliver the package back to the Collective and wipe out their hive mind. The only portion of their fleets that might be immune would be the ones already deployed and enroute to Earth, allowing humanity a chance to wage a war against a finite enemy rather than an unending horde.
Departure
Upon meeting with the Elma resistance cell, Draco left Earth after only a few days on the last leg of his mission. He was impressed by the toughness and tenacity of humanity, and felt that they didn't need someone like him to tell them how to fight. Everything he had seen from our history and fiction told that we had the art of war pretty well in hand.
Draco's current whereabouts or even whether he still survives is unknown.
