Who do you think is the best Side-Kick in the Flash family ? I think redhead Wally West is the best overall in the Flash family that’s my Flash Fact! Let’s have some fun also you can use the show or the comics for your sources!
Oh, I can’t think of the original Wally West as a sidekick. That’s my Flash! I’ll go with Impulse.
I’ll have to agree with @ralphsix, and say impulse.
