possible blue streak characters

barry allen:

+could be supercharged because of the singularity, making him blue

+definitely grant gustin in the suit

-its repurposed footage for sure

+the whole clip has to do with him

he "doesn't know what's happening to him" maybe he's becoming the black racer.

jay garrick:

+him talking in the intro

+he wears blue pants

zoom:

+it says zoom is coming at the end of the footage

+jay garrick is talking about him

-no reason for zoom to be blue.

wally west:

+it's a young man in the suit, likely not barry

-its repurposed footage for sure

-wally has 0 relation to the color blue

+in recent comics, wally has worn a blue suit.

-but the trailer had nothing to do with wally.

black racer:

+blue energy, which is neither negative or positive sf (yellow= positive, red= negative)

90% chance it's jay garrick. he's talking in the intro. he's the only announced speedster with a connection to blue. while he is talking about zoom and it does say zoom is coming, it's very likely that is just jay coming from earth 2 to warn star labs, just as they said. also the panel had a lot to do with him, so it's likely they were trying to drum up hype for him.

it could also be the black racer or barry as the black racer. wally is also an option based on his recent blue suit.

maybe zoom, but i see him with having either black or red energy.
