Cisco Ramon

"I make the toys, man!"

- Cisco to Barry Allen on his role in their team

Cisco Ramon is a mechanical engineering genius at S.T.A.R. Labs. He came from a rather poor Puerto Rican family, and provides much-needed comic relief around his stiff workplace. He works frequently with Caitlin Snow, his co-worker and good friend.

Freshman at S.T.A.R. Labs
During his first year at S.T.A.R. Labs, Cisco Ramon became quickly at odds with his co-worker and senior, Hartley Rathaway. When professor Harrison Wells introduced Cisco as the newest member of Hartley's team, the latter became skeptical of him, namely because on Cisco's penchant for hipster T-shirts. Hartley was likewise mildly annoyed when Harrison placed Cisco on the same level as him, saying that "I have a good feeling about him, just as I had about you". While spending time together, Cisco and Hartley openly expressed their dislike for each other, with Hartley snidely remarking on Cisco's argot and Cisco telling Hartley that if he thought him incompetent then he should try proving it to professor Wells. In order to spite him back Hartley stated that Cisco would not last more than a week until he left S.T.A.R. Labs. Also of note, Cisco first met Caitlin Snow while she was also taunting Hartley.

Particle Accelerator Incident
After the S.T.A.R. Labs particle accelerator was switched on, it worked for a few minutes, before it began to malfunction. Cisco was sent down to the core chamber with Ronnie Raymond to shut it down. Once they got down there, Ronnie requested that Cisco put the accelerator on lockdown if he wasn't back within two minutes. He was forced to lock it down, much to his distress and was promptly joined by Caitlin Snow. They were contacted by Ronnie, who told them of his plan to direct the impending explosion upwards rather than out, and so Cisco had to adjust the particle parameters to compensate for the change. During the particle accelerator's resulting explosion, Ronnie was presumably killed.

Following an accident involving lightning striking him, Barry Allen was put in a coma. After his situation got critical, he was moved to S.T.A.R. Labs where he was stabilized. Sometime following his move, Cisco, along with Caitlin, met Felicity Smoak during one of her visits to see the patient.

Time in Starling City
A little while later, Cisco and Caitlin were asked to pack up a S.T.A.R. Labs warehouse in Starling City, following the massive explosion that occurred in Central City. The two were doing an inventory count, discussing the particle accelerator's explosion, when they heard movement in the warehouse. They went to investigate, only to find a security guard standing there. Cisco assured him that they were almost done, though he just stared them down, creeping him out. Before the man could reply, he spat blood out and dropped to the ground, with Deathstroke ready behind him. The two made a run for it, managing to incapacitate Deathstroke momentarily with an old energy gun made by Arthur Light. They later reported the incident. Sometime after, they met Felicity Smoak and John Diggle at the hospital. Felicity asked about Barry's condition, and Caitlin told her how it was still the same. Cisco quickly blurted out that "Iris" had been visiting him a lot. When Felicity asked who Iris was, Cisco struggled to explain their relationship, causing Felicity to walk off distressed that "Barry's in a coma, he's already moved on". A little while later, Felicity met the two of them in a lab, with a vial of Mirakuru, telling them that she needed their help and that it would be their little secret.

Working with The Flash
Nine months after he was struck by lightning, Barry awoke from his coma to Lady Gaga's "Poker Face", a song he allegedly liked. He called Dr. Wells down to lab as quickly as possible, and explained to Barry what had happened, introducing he and Caitlin. The two took a break as Wells showed Barry around S.T.A.R. Labs, explaining in depth what had actually happened. Later, after discovering that he had the ability to run super fast, the team of four headed down to an airfield. He had Barry put on a suit of his creation, which would hold up when he ran fast as well allowed them to monitor his vitals and energy output. He stood back, holding a radar speed gun, as Barry raced off, knocking over Cisco. He continued to monitor his speed, before he tripped over in to barrels of water. They headed back to S.T.A.R. Labs where Wells and Barry discussed the potential for the existence of other people like him, specifically another who had super speed like Barry, though Harrison was certain that Barry was unique. He left to meet Iris. After an encounter with Clyde Mardon's weather manipulation, he returned to S.T.A.R. Labs where he was angry at Wells for lying to him in regards to metahuman abilities. Cisco found the idea of controlling the weather cool, but Barry guaranteed that it wasn't cool, as it had caused a murder. Barry returned later, sorry, offering an apology in return for Cisco and Caitlin's help in catching rogue metahumans. They agreed to help, and Cisco revealed a suit he'd designed for use by firefighters, which he believed would suit Barry's purposes well. Barry donned the suit and headed out to where they pinpointed Mardon to be. Cisco and Caitlin communicated with Barry, giving support. When Barry began to attempt to unravel it, Cisco stated his belief that Barry could withstand the pressure, which he eventually did.

After a run-in with a strongman at the Central City National Bank, Barry arrived back at S.T.A.R. Labs with a wrongly-healed ankle, after having previously broken it. They decided to re-break it, and Cisco did it as quickly as possible. Following that, Cisco and Caitlin tagged along with Barry to grab some DNA samples from the crime scene at which the strongman had been. While analyzing the sample, they helped Barry find a group of chimpanzees that had escaped from Central City Zoo. As he locked them up, they revealed that the DNA sample was that of Joey Rose, a former strongman at the Central City Circus. They delved deeper in to the closed circus, discovering that its owner had escaped from Belle Reve and killed several people. They notified Barry of this, while Dr. Wells also provided some details he knew on Mr. Bliss from having attended the circus previously, and Barry left to find the circus. Having been gone for a while, Cisco and Caitlin took a truck and crashed through the tent of the circus. Cisco grabbed Barry and Caitlin attempted to drive away, however their truck was lifted up by Joey Rose, who threw it some distance from the tent. As they crawled from the wreckage, they encountered the snake lady. The lady promised to let them pass, but Caitlin believed it to be a trap. The lady assured her that she was genuine, as they were only compliant to Mr. Bliss otherwise torture would be inflicted upon them. Before leaving, Caitlin asked what all of it was about, but the woman was only aware that something big was happening. They headed back to S.T.A.R. Labs, where Caitlin explained what had happened to Barry and Cisco further explained what the snake lady had told them. Caitlin suggested that she could experiment with psychotropic drugs on Barry, though she was unsure how he would react. Cisco noticed that Mr. Bliss had arrived at a Central City Cougars match, so Dr. Wells urged that they go down to warn everyone. Having destroyed the work van, they took Cisco's car, which Caitlin found unhygienic and tiny. As they arrived, they noticed that The Flash had already evacuated everyone. Iris greeted them and they Cisco claimed that they were there for the circus.

Cisco directed Barry to a burning building to save people inside. Midway through, Caitlin walked in, causing Cisco to shut the computers off quickly. Caitlin realized what they were doing and after Barry had saved everyone, he returned back to S.T.A.R. Labs. Cisco explained how he was the "eyes and ears" and Barry was "the feet". He queried Barry about his vitals randomly spiking during their escapade, though the latter claimed to be perfectly fine. After later fainting due to using his super speed, Barry returned to S.T.A.R. Labs, where they monitored him. Caitlin got angry at Barry, which Cisco claimed had only happened at such a level since Ronnie, her late fiancé. Wishing to see why he kept fainting, Cisco modified a treadmill to fit Barry's needs. They had him gradually work up his speed while monitoring his vitals, before they noted his glucose levels, causing him to faint. When he woke up, they explained that he had acute hypoglycemia, as he wasn't eating enough. Cisco had determined that he needed to eat the equivalent of 850 tacos (though figured that it would be different for cheese and guacamole tacos). Detective West promptly arrived and Cisco watched on as they argued, Barry claiming that Joe had no control over him. Later, after a run in with another metahuman, Danton Black, and his many clones, Cisco was annoyed that Barry had gotten blood on the suit, which he'd made. However, Barry reasoned that some of the blood was Black's, leading to Cisco nicknaming him "Captain Clone", though no one seemed to like the name. They gathered some more of the blood and Caitlin was able to trigger the replicating process in Danton's cells, making an entirely new clone. They were able to guess that it was acting as a kind of "receiver", hence why it wasn't immediately attacking them. Suggesting that Barry go after Danton, Cisco presented Barry with a high-calorie protein bar to keep his metabolism in check. When he was in the field, the team provided support as per usual for Barry. Following Danton's ultimate death, they watched it on the news, Cisco expressed that "Multiplex", as he renamed him, couldn't hurt anyone else. Barry assured that the three of them were always with him, and that really all of them had been struck by lightning, not just Barry, at least in the metaphorical sense.

A while later, Cisco alerted Barry to a man with a gun in a getaway car being chased by cops, who Barry sped to and placed in the cop car within a matter of seconds. The following day, after the Darbinyan crime family were gassed to death by a presumed metahuman, the S.T.A.R. Labs team began researching what they could, all of them excited by the potential prospects. Joe noted that they would have to find somewhere to hold them, as Iron Heights was less than ideal, and Cisco suggested the particle accelerator. Cisco and Dr. Wells went down to the particle accelerator's core chamber, where Cisco had a hard time being due to the former night's events. They headed back up, Cisco keen to leave the area. The two of them assisted Barry after he went after the gaseous metahuman, pinpointing his location. Barry soon inhaled some of the man's toxic fumes and was forced to race back to S.T.A.R. Labs, where they extracted the gas for sampling. As Barry woke up, they discussed being able to find the metahuman's identity, whereupon Cisco instead nicknamed him The Mist. Cisco and Wells went on to identify the gas, noting that although it was hydrogen cyanide, it had traces of a sedative (specifically that used on death row inmates before execution). They identified the metahuman, Kyle Nimbus, and his next target, Joe West. As Barry sped to Iron Heights, where Joe was visiting, Cisco offered to help Barry break in, though Barry claimed to have known how to since age 11. Barry eventually beat The Mist, capturing him, and they put him in their makeshift particle accelerator prison. Caitlin was skeptical that the prison would hold, though Cisco was certain that it would, as it had a super-conductor 100,000 times the strength of Earth's magnetic field. As Dr. Wells left, Cisco attempted to apologize for the night of Ronnie's death, however Caitlin admitted that she was okay, as she was even more proud of Ronnie. The two headed out to the movies, followed by ice cream.

Cisco played table tennis with Barry as Barry was also playing a game of operation with Caitlin and a game of chess with Harrison Wells to which Cisco lost. Soon after, they were alerted of a bank robbery by Leonard Snart. Later when Felicity visited the team, he learned that Barry knew who The Arrow was, which he found sweet. Cisco was later yelled at by Harrison Wells, who was furious Cisco built the cold gun, a weapon powerful enough to even harm Barry, despite his speed. Cisco later revealed he built the gun in fear Barry would become a psycho like the other meta-humans. Cisco managed to find a way to track down Snart by using triangulation though Felicity intervened as she managed to track him down in under a minute, as opposed to Cisco who claimed it would take half an hour. When Barry decided to take down Snart by also turning off his communications, Cisco along with Caitlin were told by Felicity that they should help Barry, despite his orders. Cisco, Caitlin, and Felicity later arrived with the S.T.A.R. Labs vacuum cleaner, claiming to Snart that it was the prototype cold gun, to threaten him to leave. Back at S.T.A.R. Labs, Harrison told Cisco never to create such a weapon again.

Personality
Cisco is kind, caring, intelligent, and a laid-back young man, who often at first glance seems unable to take things serious. However, he has often proven to be surprisingly focused when it comes to helping Barry fight against crime. It is apparent that Cisco is a nerd in many of the conventional ways. He has a clear love of comics, sci-fi and pop-culture, and is very excited to see such concepts made real for him, such as witnessing super-powers from assorted metahumans, in particular Barry and his super-speed. His love of comic characters has driven Cisco to often come up with names for Barry's assorted Rogue Gallery, such as Captain Cold. Cisco has great pride about his tech to the point of being extremely protective of it, such as becoming angry when Barry told him that his Flash costume was destroyed by Bette Sans Souci. Cisco is also a very careful planner as he invented a weapon specifically meant for taking down Barry in the event he turned into a corrupt metahuman.

Abilities

 * Genius-level intellect: Cisco is very intelligent, as evidenced by the crucial role he plays in Barry Allen's team, he along with Caitlin Snow were able to create a cure for Mirakuru, he created The Flash costume, (although it was originally design to be used by the Central City Fire Department) that would later be used by Barry Allen, he built a treadmill designed to handle Barry's super speed, Cisco created a very calorie-dense series of protein bars for Barry to eat in order to avoid hypoglycemia. He also designed the cold gun, which was capable of harming Barry.
 * Expert computer hacker: Cisco is a highly-skilled computer hacker, capable of breaking into any computer system, which makes him a valuable asset to Barry Allen's team, however, his computer hacking skills are not at Felicity's level.
