High-T

"You can really feel the history, hero, discovering gang leaders to civilizations!! The first failure of my perfection!!! We made history here, didn't we? There is no stopping this!! With this weapon I have, every planet will deform, starting with this one!!"

- T revealing his ultimate ambitious scheme about the weapons the MIB have built for him.

High-T is the main antagonist of the 2019 sci-fi film Men In Black: International. He is a ruthless and ambitious high-ranking member of the Hive who disguises himself as the no-nonsense head of the MIB branch of the United Kingdom.

He was portrayed by, who also played Ra's al Ghul in Batman Begins, Bad Cop in The Lego Movie franchise, and Clinch Leatherwood in A Million Ways to Die in the West.

History
He, at first, introduces himself to Molly 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 impression is that his rival, Agent H is the treacherous alien warlord. C then tries to destroy H, but Molly 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 irresponsible and suspicious 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 Molly and Agent H to retrieve and bring him the last piece of the superweapon which Molly has started building, which they successfully do, 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, unknowingly to them and the rest of the MIB agents. He then kills two alien twins who tried to invade planet Earth. The last piece of the superweapon is then returned to the MIB UK headquarters, and High-T tells everyone to make sure that it remains securely stored away. He then hints about his next move (which is to launch the portal by using the superweapon) as he tells Molly 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 maintain his secrets. However, Molly and H confront him. He then reveals his ambitious scheme to Molly 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 the Hive can come and take over Earth, there is no stopping him from killing all of the human beings. He tells them that now every planet will deform, starting with Earth itself. He then reveals to 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".

High-T then reveals his true alien form to Molly and H, and he ruthlessly fights them with no remorse, and only with cold blood. He then grabs H and as Molly 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, Pawny, a small alien and ally to both Molly and Agent H has her taken 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. Molly and Agent H are then both congratulated for their hard work.

Personality
At first pretending to be the head of the MIB force in the United Kingdom, 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 the Hive, not even having remorse for a human being who he would consider as a son-like figure, just as part of his manipulations and schemes.

T is a remorseless and heartless alien who seeks only power and corruption, and is obsessed with the 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 Alpha (although unlike him they are actually Pure Evil villains), as he was personally bent on reshaping the universe and despite having no remorse, he was ultimately cunning, extremely aggressive, and 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 path until he had no use for him anymore.
