I think that The Flash should have 3 villains.

Killer Frost: She should be the villain introduced at the very beginning and appeared through the entire season. I want her to get involved with the fight against villains because she still remembers her past life as Caitlin.

Reverse Flash: I think Barry may die at the end of Season 3, and I would love if the middle of the season adapted The Return of Barry Allen. Imagine this maybe as episodes 8-14.

Inertia: I think Bart may be introduced end of Season 3 or beginning of Season 4. If so, I am hoping that in episode 7, Bart is kidnapped and cloned. In episode 15, his clone would appear and be the main villain of the end of the season. (I think that they should have Inertia have Bart's DNA instead of looking alike, because having a CW CGI fight would probably not look very good, just because of their CGI.)
