10 Times We Saw Behind Batman's Mask In The DCAU
9. Flash and Substance
It would be difficult to find two heroes more opposite than Batman and Flash (okay, Batman and Superman, but that would be too obvious). Wally West's depiction in the JL and JLU shows was that of a light-hearted and slightly-egotistical, but incredibly generous hero who sees protecting Central City as an honour, not a duty.
In the JLU episode Flash and Substance, a Flash museum is being opened in Central City, meant to recognize Wally's crime-fighting accomplishments (the museum is also packed with Easter eggs alluding to the Flash's comics history all the way back to the Golden Age).
After transporting to the Watchtower and finding the rest of the original Justice Leaguers engaged in missions, Wally not-so-subtly hints that he would love for Bruce to attend his 'Flash Appreciation Day.' Despite showing complete disinterest, Bruce ultimately sighs before simply asking 'What time?'
Bruce recognizes how important it is for a heavy-hitter of the League to be at Central City's 'Flash Appreciation Day' and that Wally really is a sincere hero who views something that Bruce would never want for himself as a huge deal.
Not only does Bruce agree to attend, he 'persuades' the equally pessimistic and hard-edged New God Orion to accompany him with nothing more than a look, in a truly inspired bit of banter between voice actors Kevin Conroy and Ron Perlman.
