Suggested by Sonic Both of these guys are some of the Flash’s most well known villains. Their abilities both have some solid advantages against each other but ultimately I see the Mirror Master coming out ahead here. Put it this way, while Cold can freeze his mirrors for a while, Mirror Master can just keep switching them out and using new ones. He has an incredible supply and all it takes is one misstep and Cold would be in the mirror world and unable to mount a comeback. This is why I have him going down here. Mirror Master wins.
