Shutdown

Shutdown is an evil trainsformers bounty hunter.

Bio
Even the Deceptitrains including Megatrain are afraid of this guy. Shutdown is a bounty hunter at heart. He always fulfills the contracts and missions he is assigned to as long as he is paid. He doesn't really care what he has to do in order to fulfill his contract, eager to destroy entire planets if it's necessary. His respect for other species is not too great either, sometimes mumbling about his own clients and speaking to them sarcastically. Shutdown's been known to loot weaponry from the foes he kills, so his armoury is constantly changing.

Personality
Answering only to his enigmatic "true Train-Prime", Shutdown holds himself above the Autobot/Decepticon war and sees both sides as squabbling children that he has to rein in personally. He doesn't think much of other civilized species across the galaxy (particularly humans), though he isn't above working with them if it suits him. And he has three things in mind he likes to do "Kill, torture, and imprison", and all he cares about is money. And he takes no nonsense, and rules his ship and alliance with an iron fist.

Physical Appearance
Shutdown has the same body design as the Iron Giant, but with some modifications. He has the same face as Lockdown with a scar, but with same saber teeth up and down. And when he hunts he has the same mask as Peter Quill (Star-Lord) with some modifications too. Such as night vision, heat source, and tracking who he is after.

In Wrath of the Century
Upon arriving on Earth to proceed in completing his mission, Shutdown had, at some point, interacted with Harold Attinger and learned of his purpose of eliminating all Trainsformers from Earth. The two would form a partnership, and a mutual respect, following a deal that Shutdown would assist Attinger's CIA unit into hunting down Trainbots being provided unlimited access to Earth's resources, in exchange for locating Thomas. He finds Socket, and asks him where is Thomas, and when Socket did not tell, Shutdown simply kills him by ripping out his spark.

Later on, Attinger meets up with Shutdown to discuss their partnership. Shutdown, however, is unimpressed with Attinger and confronts him over the lack of his and his unit's attempts to capture Thomas before questioning their partnership, with Attinger attempting to ensure Shutdown about their joint-quest for achieving their purposes. Afterwards, Attinger suspiciously questions Shutdown over his motives for capturing Thomas and goes on to ask his true intentions, only for Shutdown to respond by warning Attinger about how they're supposed to settle their partnership, blaming Attinger and his mercenaries for causing Thomas to escape across the world.

When Thomas' location is discovered, Attinger sends his personal henchman James Savoy alongside his mercenaries to confront Thomas before warning Shutdown about this. Shutdown gets himself into position where he shoots down the house of Joe Lamb after witnessing Thomas and his human allies, including Joe, fleeing. Shutdown gives chase and catches up with Thomas, but is unable to apprehend him when Thomas fights back. Shutdown then uses one of his grenades to target Thomas' human allies, but it has failed to kill one, while the others flee with Thomas.

After reuniting with the other Trainbots and Thomas' friends, Thomas gradually begins to learn of Shutdown's presence and his friendship with Attinger, whom Thomas vows to personally kill for his cause against the Trainsformers. As the story goes on, Shutdown unknowingly gets word of Thomas fighting Galvatrain in a rendezvous location and proceeds to intervene their confrontation by heading there and shooting down Thomas. As Galvatrain flees, Shutdown approaches Thomas and reveals his true purposes towards him, revealing his affiliation with the true Train-Prime in the process. After capturing Thomas aboard his ship, Shutdown heads down to meet with Savoy and his henchmen to honor his deal with Attinger by giving them the Pod, a bomb that will turn the city into Trainsformium, the mineral that all Trainsformers are made of. He then leaves them to depart before preparing to launch out into space, but he discovers that the Trainbots, alongside the other heroes, have come to rescue Thomasand sends his hunting party to dispose of them, which is unsuccessful, allowing the Trainbots to rescue Thomas and for all of them to quickly escape Shutdown's ship just as it takes off.

Having discovered this, and also finding out that Thomas had freed his Dragon Bot captives as well, Shutdown furiously returns to Earth with the intention of hunting down Thomas and reclaiming his Dragon Bots by any means necessary. He gets word from Attinger about Thomas' current position in Los Angeles, and proceeds to active his magnetic weapon under his ship to recapture Thomas and the Dragon Bots. He almost succeeds after leveling Los Angeles and nearly killing the Trainbots (having outmaneuvered Galvatrain's Deceptitrain army and the remainder of Cemetery Wind's forces, including Savoy), but Thomas manages to destroy the weapon and heads off to confront Shutdown, who disengages from his ship and engages Thomas in a one-on-one brawl. During the battle, Thomas gains the upper hand until he notices that Twilight is held up at gunpoint by Attinger. Thomas is forced to save Twilight by killing Attinger before resuming his fight with Shutdown, who uses this distraction to overpower Thomas and impale him against the wall with his sword. After disgracing Thomas for betraying his kind over a worthless equine, Shutdown is attacked by Twilight before getting fought by Rosie and Percy. He easily defeats the two before battling Twilight, Spike, Shining Armor, and the royals, going on to dispose what remains of his sanity when he declares his intention to kill everyone. While Brian and Sylveon free Thomas, Shutdown corners Twilight, Spike, Shining Armor, and the royals and prepares to finish them off. Before he can kill them, however, Thomas reclaims his sword and surprises Shutdown by impaling his spark before slicing him in half, killing the villainous bounty hunter, and avenging some of the Trainbots he had killed.

Shorty afterwards, Thomas escapes with Twilight, Spike, Shining Armor, the royals, Brian, and Sylveon after using Shutdown's final grenade to destroy Galvatrain's remaining henchmen, which ultimately eradicates Shutdown's deceased body into ashes alongside Attinger's.
