Typhoon and Killer Frost for Me Personally but That's Not Saying Much

Slipknot is kinda funny. He's a normal dude who fights Firestorm with Ropes

What?! No Multiplex?!

Sorry

Besides Multiplex works more as a Green Arrow Villain than a Firestorm Villain In My Opinion

Except Multiplex is literally empowered by the Firestorm Matrix, same as Firestorm. His origin is even interwoven into Firestorm’s origin. Multiplex was Martin Stein’s scientific rival, and their lives came to a head when both the villain and Stein/Ronnie were irradiated with the nuclear energies that gave them all their powers. Multiplex is and will always be a Firestorm villain first and foremost. It’s practically undeniable.

For me, Typhoon and Silver Deer are favorites. I like Black Bison a lot, but I like him because his genuine self isn’t villainous at all. John Ravenhair ended up possessed by the spirit of his own malicious grandfather. So, when he’s John, he’s a teacher, and he’s a good guy. But when the Black Bison personality takes over, he’s not in control and is villainous. I had always hoped to see John Ravenhair exorcise the spirit and learn to use his Black Bison powers on his own to use for good purposes. Alas, that hasn’t come to pass.

There are a lot of Firestorm villains I really like, but one of my favorites is Killer Frost.
