Matthew Kim

Matthew Kim, nicknamed Melting Point by Cisco Ramon, is an EMT at Central City Hospital, and a meta-human with the ability to swap people's DNA.

Biography
Working at a hospital as an EMT for an unknown amount of time, Matthew was on the bus that was hit with dark matter from the Speed Force heading to work. As such he became a 'bus meta' with the ability to manipulate DNA.

6 months later, he used his powers to take a robber's meta powers allowing him to be caught. Unknowingly, he placed those powers into Jaco Birch, a bystander at the robbery. He then fled the scene.

At the hospital where he works he was confronted by Barry, Iris and Joe and thinking they want to hurt him, took Iris hostage and when Barry made contact with him, he transferred Barry's speed to Iris and fled again.

In the street, Jaco Birch used his new abilities to cause massive destruction wanting money. Matthew tried to talk him down and use his powers on him again but couldn't. Fortunately, Iris showed up with her new abilities to stop him. He then reversed his actions on Barry and Iris giving Barry back his speed, remaining at S.T.A.R. Labs for protection from DeVoe.

Powers

 * Meta-human physiology: After Matthew was struck by the dark matter energy after the Flash was released from the Speed Force, this altered his DNA and cells, enabling him to access his newfound powers.
 * DNA manipulation: Matthew's powers allow him to dissolve the bonds of DNA in a subject and transfer pieces of that DNA into others with a simple touch.
 * Power transferal: By moving the DNA markers that give a meta-human their powers, Matthew can give someone else those powers as he removed Fry's powers and accidentally placed them into a bystander, Jaco Birch at a bank robbery and gave Barry's powers to Iris.

Weaknesses

 * Physical contact: In order for Matthew to use his powers on a subject, he must be able to physically touch them. Which can be difficult for him such as the time where he tried to take Jaco Birch's powers from him, only to be almost burned by him had Iris not saved him.
