~DCAU (Earth-12?)~
There were two guards that held The Flash down –kneeling in front of Lex Lu –no, Brainiac.
"Looks like I kill you,… Then Armageddon." Brainiac said, pointing a gun at The Fastest Man Alive.
And for one of the very few times in Wally's life since he gained his powers, the world moved to fast.
He didn't hear what Brainiac said, just that he said something.
He just knew one thing, one word by heart. It was almost an instinct of his.
Run.
Just run, and don't look back.
The Flash saw the whole world flash before his eyes as he ran, not stopping as he finished each lap around the world, gaining speed and velocity with each step he took, hitting Brainiac each time as he passed.
Hitting him once, twice, three times, four, five, six, seven, eight, nine, ten times, each after a shorter time, but harder than the last.
When Wally finally stopped, he faintly heard a soft crackling static in the air around him.
He wasted no time, gave no time to Brainiac to recover, as Wally showered him in punches to the chest, each at light speed.
After he was sure he had finished Brainiac up, he stood up and looked at his hands, each were vibrating and almost transparent.
He looked up to his teammates from the newly-created crater he stood in.
"I feel kinda… funny." He said, and was shocked to hear his voice.
It was shaky and sounded almost like how the voice of a ghost would sound like in one of his movies.
Transparent.
He heard the other Leaguers call out to him in desperation, but when Superman started to run towards him, the world turned black, cold, and silent.
