Meta-human cure

"Rule number one. We're not just here to make a cure, we're here to make a choice."

- Cisco Ramon to Caitlin Snow The meta-human cure, also commonly referred to as the cure or the meta cure, is a cure created by Cisco Ramon and Caitlin Snow. The cure is used to remove a meta-human's powers by suppressing the dark matter in their pituitary gland. Team Flash decided that they didn't want to use it as a weapon and not force the cure on anyone.

Creation
After removing the shards from Cicada's dagger in Cisco Ramon's hands, Cisco decided to do some tests on them and his hand's tissue. These tests revealed that they weren't dampening Cisco's powers but removing them, giving Cisco the idea to use them to make a meta-human cure.undefined

At first Caitlin Snow wasn't on board with the idea as she thought it wasn't necessary for a cure to exist, neither was Killer Frost who sabotaged Cisco's first try at making the cure. When she did that, Cisco told her that she ruined his only chance to have a normal life. This speech caused Caitlin to understand Cisco. That's why she took him to her dad's old lab to use his research to do the opposite of creating a meta-gene. In exchange for them working on it together they set up some rules, the most important one being that they will never force a cure on anyone.undefined

Killer Frost still didn't agree with the creation of the cure so she tried to sabotage it by making changes in Caitlin's equations, while Cisco was work in in the Tannhauser offsite. Caitlin later realised she needed a DNA sample from a meta-human who hasn't fully bonded with dark matter to make the cure. To get her point of view through to Caitlin, Killer Frost destroyed all of her equations before getting recruited to help Team Flash locate meta's that were in danger. After getting a speech from Ralph Dibny why she shouldn't be afraid of Caitlin making the cure and possibly take it, she decided to help them so she took some of Cicada's blood when fighting him and gave it to Caitlin.undefined

Cisco kept working on the cure, seeing that something was missing. After being taken to a bar by Ralph, he starts talking with Kamilla Hwang. After she told him she had a sister, he realised that that was what he needed, the DNA from siblings where one of them became a meta-human and the other one didn't. And so he located a pair of meta and non-meta siblings to get the cure as good as done. Barry then revealed he wanted to use the cure on Cicada.undefined

Cisco sent the sample of the cure to Caitlin to test if it could work. Her test showed that everything should check out. She then sent it back to Cisco for final processing. She then revealed that giving the cure to Cicada wouldn't be that easy, since the cure isn't instant and takes about a minute to work and they have to keep him still during that time. Caitlin had a solution for this. They needed a Neuro-Stasis Field Generator, which was located in Goldface's black market. Barry and Ralph tried to get their hands on the Generator, but failed. Luckily for them, Iris West-Allen found out about Cicada's wound in his chest. Knowing about his weakness gives them an other way to give him the cure.undefined

Cisco finished the cure but then found out that they had to wait 29 days before they could use the cure. It had to synthesize for that long, unless they took it into the Speed Force. So, Barry took the cure with him into the Speed Force where it would take about 1 hour for the compound to synthesize by using the tachyons located in the Speed Force. When Barry returned the cure was fully synthesized and ready to use.undefined

Use
Now that the cure was ready, they needed to test it on a meta-human. After talking about multiple options, Team Flash decided that the best meta to try the cure on is King Shark who was being held at A.R.G.U.S. But, due to an interference from Grodd, King Shark escaped. When they found him again The Flash just used the cure on him without asking. King Shark then returned to his human form, Shay Lamden. Back at S.T.A.R. Labs Cisco and Caitlin were upset with Barry because he used the cure on him without asking. There was still a problem. Since the cure was developed to bring out meta's human parts, Shay's animal parts fought back, causing in some dark matter that stayed in his pituitary gland, which meant he wasn't going to be human forever. Caitlin made sure they could ajust the cure so that it could work on him. He later gave up the chance to be fully cured to save Central City from Grodd by changing back into King Shark. After all this happened Barry apologised about using the cure on him and then came up with the idea to offer the cure to Cicada.undefined
