George Allen (Earth-2899)

"When you need me, I will be here, but right now, Central City doesn't need you to be George Allen's son. It needs you to be the Flash, my kid, the superhero."

- George Allen to Barry Allen

Dr. George Allen is the father of Barry Allen, the husband of the late Lauren Allen, and son in law to Jay Garrick. George was framed by a time travelling Reverse Flash who had killed Lauren and sent to prison. Along with the people at S.T.A.R. Labs, The League of Avengers, Joe and Iris West and multiple others, he also knows Barry's secret; that his son is the Flash.

Trivia

 * This version of Barry Allen's father is actually Asian. To one, accommodate Ezra Miller's Asian background and two, as an excuse for one of the creators to use Jet Li (Definitely not Techno Bacon).
 * He was converted to Judaism by his former wife.
