Agent James "Jimmy" Woo is a former S.H.I.E.L.D. agent who was recruited into the FBI. Woo was assigned as Scott Lang's parole officer, making sure he stayed under house arrest after he escaped from the Raft. Woo was also tasked to track down and arrest Hank Pym and Hope van Dyne for complicity.
Agent of S.H.I.E.L.D.
Jimmy Woo worked as a S.H.I.E.L.D. agent together with Melinda May. His work was enough for him to get recognized by May, who proceeded to include Woo as one of her contacts in case she needed any special help.
Working for the FBI
Scott Lang's House Arrest
In the wake of collapse of S.H.I.E.L.D., Woo was eventually recruited into the Californian FBI division. FBI stationed Woo in the Bureau headquarters in San Francisco and assigned him as a leader of his own unit, together with Stoltz, Burleigh and Pearson. Woo, however, was feeling less competent in working for the FBI because of the short list of successful missions.
Woo was tasked to supervise the house arrest of Scott Lang who had recently taken part in the battle in Germany which broke the Sokovia Accords and forced him to make a deal with the Homeland Security and German government. Alongside with monitoring Lang, FBI ordered Woo to lead the search for Hank Pym and Hope van Dyne who were wanted for complicity to Lang's crimes.
Three days before Lang's release, Woo received a signal from Lang's Ankle Monitor while he played with his daughter Cassie. FBI agents arrived at Lang's house to search the perimeter and check his monitor. Lang reminded Woo that he is got the three days before release and because of that, Lang would not escape. Woo just told him about rules of his house arrest under which FBI had to search the place if Lang triggered a perimeter alarm in any case.
Lang and his daughter tried to assure Woo that alarm was caused by an accident during their game. Lang then stated that entertaining the ten-year-old without leaving the house is no easy task before demonstrating him several card tricks that he learned from the Up Close and Magical. Cassie then asked Woo why he can not leave her father alone and Woo tried to explain Lang's crimes in simple language. However, due to his poor skills dealing with children, Woo's speech became too formalized and Cassie did not understand him.
On an unrelated matter, Woo asked whether Lang had any contact with Pym and van Dyne. Lang denied and Cassie confirmed her father's statement, saying that they hate him. Woo then reminded him that their arrest is a matter of time and according to rules, Lang was not allowed to contact them. He added that any violation of his agreement means twenty years in prison. Woo quietly asked Lang about his card tricks before he was interrupted by Maggie Lang who was mad for another breaking in Lang's house. However, Jim Paxton made it clear that the FBI were in fact following the rules.
Call from Berkeley
FBI was informed that Hank Pym and Hope van Dyne were identified by the campus police of Berkeley University. Woo and his unit, with several other agents, arrived at Berkeley to speak with Dr. Bill Foster. Foster answered that he did not meet Pym for thirty years and he is the last person he would want to visit. Stoltz did not believe him but was stopped by Woo, who wanted to know the reason of malice between Foster and Pym. Foster then calmly replied to his question that they hated each other.
- "We got them, sir. Pym and van Dyne are in custody."
"Seriously? Yes! Oh. Sorry, Scott. They were your friends. That's insensitive. I just really needed a win, you know? Anyway, I'll be back later for the official end of your sentence. Sorry for misjudging you, pal. You should feel great about yourself."
- ―Pearson and Jimmy Woo[src]
At the San Francisco FBI Office, Woo tried to learn the same Up Close and Magical card tricks that Scott Lang previously demonstrated him before he was interrupted by Stoltz. He informed Woo that he received a lead from anonymous contact about the current location of Lang who escaped from his house arrest.
While Stoltz led the FBI task force to the Muir Woods in order to apprehend Hank Pym and Hope van Dyne, Woo and his unit headed to Scott Lang's House. Breaking into the house, Woo ordered agents to spread out and search the perimeter, much to Maggie Lang's annoyance. Woo was informed by Pearson that according to Lang's Ankle Monitor he is in the bathroom. Woo did not believe it and rushed to the bathroom before he was halted by Cassie Lang who blocked him.
Maggie told Cassie to let Woo get to the bathroom but Cassie claimed that Lang is sick and barfs a lot. Woo then stated that he is a federal agent and saw things worse than vomit. However, he then hesitated, asking Cassie how much Lang barfed. Woo bypassed her and headed to the bathroom but much to his shock he saw Lang leaving the bathroom.
Burleigh then was ordered to check Lang's monitor while Maggie was still mad of FBI actions. Burleigh then confirmed that Lang's monitor did not reveal any violations and Woo convicted that he was misinformed. Pearson then received a call from Stoltz who successfully arrested Pym and van Dyne and informed Woo. He was very happy for his first "win" for a long time but then apologized to Lang for his reaction. Woo and agents then headed to the exit while he told Lang that he will be back later for the official end of his sentence.
End of Lang's Sentence
Hank Pym and Hope van Dyne were brought to the San Francisco FBI Office and Woo was going to interrogate them. However, they managed to escape and Pearson informed Woo that their van and Wasp Suit disappeared. Later, FBI agents watched the news report that showed them giant Ant-Man causing chaos at the Pier 39. Realizing that Lang violated the rules of his house arrest by leaving his house before the end of the sentence, Woo ordered agents to move out.
Driving to the pier, FBI spotted the Ant-Man Suit toward the wall of the building. Woo ordered Lang to surrender, telling that he got Lang and he had no way to escape. However, Lang did not respond and then the suit turned out to be empty. Woo then ordered to head back to Scott Lang's House.
Breaking into the house again, Woo, however, found Lang in his house playing the drum kit. Admitting that Lang did not violate his deal, Woo ordered Burleigh to remove Lang's Ankle Monitor and set him free. Woo then told Lang that he managed to get away with it this time but he will watch him and arrest him at the earliest opportunity. Lang then said that he thought that Woo wanted to invite him somewhere like a party or a dinner and Woo then asked why he would do that. Before leaving, Woo asked if Lang wanted to go out but then changed his mind and left Lang's house.
Working as a member of S.H.I.E.L.D. and the FBI, Woo proved himself as a man who follows rules by the book in any case. Knowing that Lang had three days before the end of his sentence and no reasons to escape, Woo still arrived at his house to examine the perimeter because it was one of the rules of his deal. While Woo always wants to catch Lang in illegal activities he seems to somewhat respect Lang like when he showed him a card trick. It's also implied that Woo would like to be casual friends with Lang by saying that he would like to have lunch sometime shortly after releasing him from house arrest.
Woo seems gullible seemingly not knowing that Stoltz was working under black market dealer Sonny Burch. He also showed poor skills while dealing with children, as seen when he tried to compare Lang's situation to Cassie Lang with her school's rules, only to end up getting too detailed with Lang's crimes, the laws it violated, and his deal with the government, for her to understand it.
