Luis

"We're the good guys right?" "Yeah, we're the good guys." "Feels kind of weird, you know?"

- Luis and Ant-Man

Luis is the former cellmate of Scott Lang, who assisted Lang in stealing the Ant-Man Suit from Hank Pym and participated in Lang's heists at Pym Technologies by posing as a security guard.

Arrest
"You know he was arrested for stealing a smoothie machine, right?" "Two smoothie machines..."

- Hope van Dyne and Luis

Luis was arrested for stealing two machines and was sentenced to San Quentin State Prison. There he was made the cellmate of Scott Lang, who became his close friend. Luis was released from prison in 2014. As a goodbye ritual, an inmate named Peachy fought him; Luis became the only one to knock Peachy out.

Reunion with Scott Lang
"How's your girl, man?" "Oh, she left me." "Oh..." "Yeah, my mom died too and my dad got deported. But I got the van!"

- Scott Lang and Luis

By 2015, Luis' girlfriend broke up with him, his mother died, and his father was deported; though he did keep his van. Later, a friend of Luis and his former cellmate, Scott Lang, was released from San Quentin State Prison. He decided to let Lang in on a heist he was planning with two other friends, Dave and Kurt. From multiple sources, Luis had found out that a large safe was in the basement of an old man who would be gone for a week. Initially, Lang decided against it, but after getting fired from  and the circumstances given - considering the tension between him and his family, he agreed to do the job.

Robbing Hank Pym
"Hey, if the job goes bad, you know I got your back, right?" "Don't worry. It's not gonna happen."

- Luis and Scott Lang

With Scott Lang having been fired from a job at, he reluctantly agreed to assist the team in the heist. They had a meeting where they discussed the details of the plan to rob Hank Pym's home as Luis had received important information about the layout of the house, including the safe which potentially housed millions of dollars. The heist went underway and Luis sat in the van with Dave and Kurt while Scott Lang broke into the Pym Residence and looked for the safe. Lang continued to update the team as he found and destroyed the safe, only to find what appeared to be a strange Motorcycle Suit inside, realizing that the plan was a failure, Luis apologised and told Lang to return to the van. Disappointed, Lang made it back to the van with the suit and Dave drove them back to Luis' apartment.

Unknowing Tester
"Luis, Luis, down here!"

- Scott Lang

Luis entered the apartment of Scott Lang as he was dressing for the first time in the Ant-Man Suit in the bathroom. Lang, standing in the bathtub to see himself better in the mirror, shrank by experimenting with the buttons that he found. Luis entered the bathroom and, not seeing his shrunken friend, turned on the faucet to the tub.

Recruited by Hank Pym
"Are you sure they can handle this?" "Oh we can handle it; we're professionals."

- Hope van Dyne and Luis

A few days after their initial heist, Luis, Dave and Kurt were invited back to the Pym Residence for coffee. There they learned that Scott Lang had been working with Hank Pym and his daughter Hope van Dyne with the intention of breaking into Pym Technologies and stealing the weaponized Yellowjacket Suit from the insane CEO Darren Cross. Pym discussed their professionalism and chances of succeeding in their mission. Van Dyne questioned Luis' professionalism considering his previous arrest was due to stealing two smoothie machines. Shortly after their coffee, Lang stepped back into the room wearing the Ant-Man Suit they had once stolen. Everyone was initially impressed by the look of the suit, and were then amazed when Lang demonstrated the suit's shrinking abilities. The night before the heist, Luis and the rest of the team got together to finalize the details of the plan, which would have Luis posing as a security guard at Pym Technologies, although Pym continued to question the likelihood of them succeeding.

Infiltration into Pym Technologies Headquarters
"That's what I'm talking about! That's what I'd call a... an unfortunate casualty, in a very serious operation."

- Luis, after knocking out a guard

During the heist, Luis disguised himself as a security guard and knocked out the head of security to turn on the water to allow Lang access. When a fight erupted between Lang, security, and HYDRA agents, Luis assisted Lang by knocking out some guards and then escaped with Dave and Kurt. They drove to Maggie Lang's house intending to help their friend Scott, only to find it surrounded by the police. Worried they would be arrested, they slowly drove away from the house and the concurrent duel happening there.

Falcon's Offer
"...to tell me, to tell you cause I'm tight with Ant-Man, that's he's looking for him?" "And what? What'd he say?" "He said yes!"

- Luis and Scott Lang

The following day, Luis would go to an art gallery with his cousin Ignacio and message would spread that Falcon, an Avenger was looking for Lang. Luis informed a confused Lang of the situation through one of his long-winded explainations.
