8. Captain Cold Will Become A Huge Problem
He's featured in the mid-season teaser trailer attempting to lure The Flash out into the open, so it's guaranteed he'll be back. Last time he was in Central City he pushed Barry Allen and indeed the whole Star Labs crew to the limit given the lengths to whic he was willing to go in order to survive and stay free. He managed to get away as well, so the group can't fall back on past experience of having beaten him; they didn't. All they managed to do was bluff him into walking away. This would suggest that he's going to be a bit of a problem on his own. However, it's unlikely that he's going to be on his own. Two revealed episode titles for the rest of the season include the word "Rogues". In the comics, The Rogues are a rather elite group of Flash villains who work together to fight the Scarlet Speedster. A number of traditional Rogues members, such as Pied Piper and Heat Wave, appear in the mid-season teaser, suggesting that the group isn't going to be short of members. Captian Cold is usually depicted as the leader of the Rogues, and is usually the one trying to bring them all together in a team. There's definitely the potential that he'll be putting together a team of metahumans to come after the Flash, and given that Barry Allen has often had problems defeating one villain at a time, a group of them could end up being more of a threat than even Reverse-Flash. With the not-so-good Captain set to become the catalyst for this group, he could be more trouble for the heroes than people have anticipated.
