Biography
Burch first appeared when Hope Van Dyne (the daughter of Hank Pym) arrived to his place in order to buy a part for her father Hank Pym. As it turns out, Hank intends to use the part for his laboratory (which can be miniaturized) to open up a portal to the quantum realm in order to save Hope's mother Janet (who is trapped inside the Quantum Realm). However, upon learning of this technology, rather then selling the part, Burch instead decides to double-cross Hope as he intends to steal the lab for his own purposes of making money. This forced an annoyed Hope to fight off against Burch's men before engaging into a fight with a masked criminal named Ghost, who escapes after stealing away Pym's lab. Witnessing this, Burch angrily orders his men to track down the lab and kill anyone who stands in their way.

Burch eventually tracked down Lang's business partners Luis, Dave and Kurt, who revealed that the trio are currently in the house of Bill Foster, whose adoptive daughter Ava happens to be Ghost and that she plans to use the lab to cure herself of a condition she suffered following an accident that caused her parents' demise. With this information, Burch informs his contact Stoltz at the FBI. However, Luis warns Lang, who rushes home due to his house arrest, which leaves Pym and Hope to be arrested and for their lab to be taken by Burch.

However, Lang managed to help break Hope and Pym free from custody and retrieve the lab from Burch, much to the latter's anger. The trio then set the plot of using the lab to open up the portal to save Janet. However, Burch and his men arrive to stop this, forcing Lang and Hope fight back against them while Pym finally rescues Janet from the quantum energy. Janet then used her extracted quantum power to cure Ava of her condition, and Burch ends up being apprehended by Ant-Man and Wasp (with the help from Luis, Dave and Kurt).

It is implied that Burch and his men end up being arrested by the FBI and sent to prison for their crimes while Ava escapes with Bill from the authorities.

Trivia

 * Though it would've appeared that Ghost is the main antagonist as she had bigger screen time than the other villains, Burch is the real main antagonist of the film as he had bigger plans than anyone else, even attempting to kill off Ant-Man, Wasp, and Ghost in order to get his hands on Pym's technology for himself.
