Dr Starline

Starline was calm, theatrical, and sophisticated most of the time, exuding an arrogant sense of pride in his intellect and abilities. Rather formal in behavior, he often addressed others as "gentlemen". However, he was also ruthless, sinister, and cruel, as he was willing to force Dr. Eggman to be a part of an evidently painful procedure against his will to bring him back to normal. Showing contempt for weakness, he possessed an incredible drive, as seen how he kept searching for Eggman despite becoming quite ill from sleep deprivation in the process. Despite possessing a calm demeanor, his patience did have its limits; after spending time with Eggman, Starline began showing occasional bouts of anger and frustration primarily directed at Eggman's imperfections, stubbornness, and refusal to listen to his reasoning. Ultimately, Starline would lose his patience after being fired by Eggman. In this state, he had proven himself emotionally unstable and prone to angry rants.

In addition to his intellect, Starline was quite manipulative. He could expertly use other people to his advantage in order to make them cooperate with him or lure them into traps, and he knew exactly to strike his foes where it hurt the most. However, despite considering himself brilliant, he originally possessed a subservient attitude towards Eggman and willingly submitted himself to his command.

Starline was an insane fanatic of the Eggman Empire. At first, he was willingly submissive to Eggman alone and his orders, although his fascination with the doctor made him blind and ignorant to the flaws of his idol at first. In fact, Starline was with Eggman at almost every turn during the Zombot apocalypse and was ready to come to his rescue despite not thinking things through too well.

Unlike Eggman's more overt ways, Starline was much more subtle. Notably, he preferred simply launching an ambush instead of luring someone into a trap with bait that exposes his activities. Starline similarly always covered up his tracks in various ways, thereby leaving him activities undetected by his enemies. Always waiting patiently for the right time to attack, he would only reveal himself when the time was perfect, at which point he allowed himself to be exaggeratingly theatrical. He was also very thorough with everything he does. Notably, he put his projects through hundreds of different tests until he was absolutely assured of their safety and has sufficient data samples to work out from, unlike Dr. Eggman, who would hastily begin implementing his plans without finishing the necessary procedures that would prevent the fallibility of his creations. Similarly, he took great care when preparing for direct confrontations with his foes, like luring Sonic into an environment where he was at a disadvantage and scouting out a whole mountain before-hand in order to use his Warp Topaz to its fullest and kill him on his first try. He also preferred working in the shadows and avoiding unnecessary clashes with his foes.

Like Eggman, Starline was unhappy with the chaotic and unpredictable state of the world that he intended to take control of. Unlike Eggman, however, who would seek to bring order to the planet with the blind obedience of machines, Starline had come to see that the ingenuity and will of living beings made them much more effective than mindless robots, and so he sought to use cyborgs mentally programmed to his will to bring the world under his control.

After seeing Eggman's Metal Virus plot grow out of control and being fired as Eggman's protégé after realizing the flaws of his idol, Starline came to realize the downside to arrogance and egotism. As such, he was very careful not to go down the same path Eggman has walked for years. He likewise believed that robots made much more suitable allies than organic creatures, as they were unquestionably loyal, tireless, and efficient, though only when properly programmed. As such, he ultimately strived to be a lone genius that did not need to rely on anyone.

Despite being cautious and systematic with his actions though, Starline was not infallible. Notably, he had a tendency to underestimate the situations he was in, especially those that he thought he was in control of. His experiences with artificial emotions and excitement in particular had led him to underestimate the possible dangers they pose in the wrong hands. Having been noted to love hearing himself talk as well, Starline frequently made video logs of virtually every operation he conducted, carefully documenting his very action and thought, unless he believed it was not relevant. Unfortunately, his careful documentations often turned against him as they allowed his more volatile associates to discover his true intentions and plans with them, which would result in a catastrophic outcome later. He is also shown to be a hypocrite. While acknowledging his shortcomings made him similar to Eggman when pointed out by Zavok, he remarks how Eggman suffers from tunnel-vision due to his obssession with Sonic even though he too suffers the same from his own obssession with Eggman and how the world never improves from the repetitive conflict beween Sonic and Eggman, disregarding that he restarted it by restoring Eggman's memories. Similar to how Eggman took the Zombots growing out of his control, Starline procrasinated looking into Surge and Kitsunami's resistence to his hypnosis.
