Are All the Superheroes in Amazon's The Boys Giving You Deja Vu? You're Not Alone

Since A-Train (Jessie T. Usher) is a speedster, it can be assumed that his character is The Flash of the Seven. However, he is likely a version of Wally West rather than Barry Allen since in the comics, the original speedster in the Seven is Mister Marathon and A-Train seems to have a little more trouble controlling his powers.
