Honestly, I feel like the most Barry things about DCAU Wally is certain base elements (Police scientist, Central City, founding JL member). Wally in DCAU doesn't have the same Flash family legacy ties that defined comic Wally so his personality come off more comparable to JLE/ or even Impulse like. Ultimately the point I was trying to make where each Flash adaption takes certain elements (Occupation, from mainly Barry, Wally and arguably Bart in their "Streamlining" of the character for a mainstream take of a Flash, regardless of who is underneath the scarlet cowl. Ever since the 1990's tv show and the DCAU Flash. But it doesn't help the feeling of the Flashes becoming interchangeable after a certain point.
