Is the doctor in the flash a yellow flash? (I watched the ninth episode today)

Reverse lightning. Scientists in the 25 th century recreated Barry's experiment of gaining rapid strength in himself. They worship Barry, but they are defeated by Barry after crossing, vowing to get back at him, but they can't kill him just to torture him (otherwise it would be a fallacy).

The above is a comic story. The doctor is a swan, not a lightning bolt.
