If Wally speedforce blitzes him hellfire ain't gonna do nothin. Nada zip. Your talking about a guy resisting greater than light speed friction with speed force barrier. If it can resist that, based on environmental damage and resistability of enemies to Rider's flames it won't bother flash in the slightest. He blitzes says wtf flaming skull man and proceeds to pummel his bones into dust.
Flash is unbeatable. Nobody else's powers or durability matters when you can run really really fast. LOL. Flash has never ever lost (lol) because he's so damn fast. His superspeed is the coolest, greatest, and best power in all of comics and it trumps all other powers. Because of it he's the most powerful character in all of comics!

Most people believe Evolution not because they themselves are dumb, but cause they trust the "experts" who are feeding them evolutionary fast food, and so they don't bother questioning whether or not it's true.
No. At least not a Spirit in control Ghost Rider. A human control Ghost Rider can be KOed by mid tiers.
Spirit control GR has the ability to instant reform his head via hellfire, and body for that matter. He can withstand the best attacks of Thor, Hulk, or Dr Strange.
Then there is the whole fact GR has no brains or anything to go unconscious from. In short only powerful magic can harm a spirit control Ghost Rider.
