"The Flash" editor Brian Augustyn asked Wieringo to try out for "The Flash". After submitting some sample pages of the Flash running, Wieringo was offered the penciling duties on Volume 2 of that series, on which he was paired with writer Mark Waid, and on which he rose to prominence in the industry, drawing all but two issues from #80–92 (Early Sept. 1993–July 1994), plus #0 (Oct. 1994). He additionally penciled covers through #100, #118–124, and 128–129, and for "The Flash 80-Page Giant" #2 (April 1999). Wieringo and Waid co-created the young speedster Bart Allen, a.k.a. Impulse, in "The Flash" vol. 2 #91 (cameo) and #92 (first full appearance).
