User blog:JMOfficial/Flash Big Bads in the Future

So, I am making this blog post, to ask, what villains would you like to see in future seasons of The Flash? In my opinion, Season 4 should end with a tease of Godspeed and Bart arriving in the past. Then, with Season 5, Godspeed is the main antagonist, Inertia is the secondary antagonist. Godspeed will be revealed, and Barry will die during a hopeful Crisis crossover. Inertia isn't revealed, and returns as a major villain of Season 6. What are your guys thoughts, and what villains would you like to see?
