High-T

High-T is the main antagonist of Men In Black International. He is a ruthless and ambitious high-ranking member of Hive and he disguises himself as the no-nonsense head of the MIB branch of The United Kingdoms. He is portrayed by Liam Neeson, who also played Ra's al Ghul in Batman Begins and also Bad Cop in The Lego Movie franchise.

History
He at first introduces himself to Moly and recruits her as an agent for The MIB. He tells her that he expects from her great things. He later researches the suspicious alien individual who attempted to destroy the world with a superweapon. One of his loyal agents, "C" has announced that his impresion is that his rival, Agent H is the treacherous alien warlord. C then tries to destroy H, but Moly convinces T that he shouldn't be destroyed, and that she can tell the truth. She insists to T that if the alien was caught in an area where only MIB agents were operating, then the traitor must be someone working for The MIB, or worse, it could be one of the MIB's top agents. He orders C to take care of it, and Molly to help him to find and build a weapon against the alien scums. He then gets upset at Agent H for being iressponsible and suspicous in the recent times, even stating that he had lost one of his assisting agents during previous operations. H tells him that he will not fail this time. High-T later sends Moly and Agent H to bring him the last piece of the superweapon which Moly has started building so it can launch a portal to the Hive base in the outer space so the aliens from Hive can take over the planet and occupy Earth, unknowningly to them and the rest of the MIB agents. He then killed two alien twins who tried to invade planet Earth. He then hints about his next move (which is to launch the portal by using the superweapon) as he tells Moly that her heroic acts will never last. He later goes to test the weapon and deletes all the evidence that there was an alien traitor among them in order to mantain his secrets. However, Moly and H confront him. He then reveals his ambitious scheme to Moly and Agent H, telling them that they have created a history for hive all along and that now that he can shoot a portal to the outer space so Hive can come and take over Earth, there is no stopping him from killing all the human beings. He told them that now every planet will deform, starting with Earth itself. He then reveals H that he was just another tool for his ultimate scheme and that he never had feelings for him, as High-T even sarcastically remarks that he was "always like a son to him".

T then reveals his true alien form to Moly and H, and he ruthlessly fights them with no remorse, and only with cold blood. He then grabs H and as Moly tries to save him from being mutilated by the ruthless alien warlord, T grabs her and throws her into the portal, so the Hive members will kill her when she gets to the other side. However, a small alien and ally to both Moly and Agent H has taken her back to Earth, allowing her to grab a laser gun and shoot both T and the portal, thus causing the ambitious High-T and his portal to disintegrate and never return.

Personality
At first pretending to be the head of the MIB force in The United Kingdoms, he was revealed to be one of the cruelest threats that The MIB have ever crossed paths with. He is vicious, calculating, manipulative, cunning and genocidal, as he intends to take over the universe for Hive, not even having remorse for a human being which he would consider as a son like figure, just as part of his manipulations and schemes. T is a remorseless, heartless alien who seeks only power and corruption and is obsesed with Hive taking over the universe with his own weaponry and inventions. He was willing to wipe out the entire human populace as well as destroy any other opposing alien being in the universe. He might even be considered as one of the most cruel, vicious and ruthless villains of the MIB franchise, along with Boris The Animal, Vangus and The Alpha; as he was personally bent on reshaping the universe and despite having no remorse, he was ultimately cunning, extremly aggressive and he could even be considered corrupt among the human society. He was willing to mutilate anyone who stands in his way, and he developed an obsession with Agent H following his paths until he has no use for him anymore.

Trivia

 * He is the second live action Men In Black villain to be considered as Pure Evil. The first is Boris the Animal.
 * He is similar to Ego The Living Planet from the MCU; they are both purely evil and seductive galactic overlords who treat the male protagonists (Starlord and Agent H) as if they were their own son-like-figures just so they can succeed with their own ambitious, world-threatening and genocidal plans.
