The Flash: 3 Different Avatars of Jay Garrick

Jay Garrick (Zoom):

He is a dark version of Jay Garrick with a blue lightning/ speed force. He acquired speed-force as a result of particle accelerator explosion, experimented with sizeable quantities of Velocity-9 drug, got addicted to it which had a negative impact on his mind. He could also be a Cobalt Blue type of character i.e actual physical twin before the explosion of particle accelerator. He is a version of Jay Garrick without a soul, similar to the relationship between Angel-Angelus of Buffy the Vampire Slayer.

Jay Garrick (Mysterious Man in an Iron mask):

He is also Jay but the Earth-1 version of it. He is the original dopple-ganger of Earth-2 Jay on Earth-1. When Jay Garrick showed Caitlin his dopple-ganger on Earth-1, he was actually Zoom whereas Hunter Zolomon is taken and caged in Zoom’s lair.

Jay Garrick (Flash of Earth-2, Boyfriend of Caitlin Snow on Earth-1):

He is shown to be former Flash with yellow speed-force, the man Caitlin fell in love with on Earth-1, he told her about the massive side-effects of Velocity-6 drug, but Caitlin took it to Velocity 9 levels that could help regenerate damaged cells. In actuality, he may be partly good, but was definitely misleading Team Flash. He is speculated to be a twin brother of Zoom from Earth-2.
