Voiced by , who previously voiced Flash in Superman: The Animated Series , the Flash in The Batman brought a fast-talking, energetic contrast to Rino Romano’s brooding Batman. Although producer Alan Burnett identified this version as Barry Allen , the character's quick wit and lightheartedness felt reminiscent of the animated Wally West.

The Flash (2004) in The Batman is a visually daring, personality-driven interpretation of Barry Allen. While his screen time is limited, his appearances – particularly opposite Mirror Master and Batman – showcase effective use of speed-based powers and a likable, humorous character. For fans of the series, he remains a memorable guest hero, though not a definitive version of the Scarlet Speedster.

The Flash appears in the animated television series The Batman (2004), which reimagined classic DC characters with unique, stylized designs. Unlike the broader Justice League animated universe of the time, The Batman focused primarily on Batman’s early years but introduced several Justice League members in later seasons. The Flash is a supporting character in two episodes and a cameo in a third. the batman 2004 flash

For the Flash, this means facing an opponent who is just as fast as he is, requiring him to use his intellect rather than just his legs to outsmart his mirror image. The climax features a stunning sequence where Batman and the Flash must synchronize their entirely different fighting styles to dismantle Mirror Master’s dimension-hopping apparatus.

Flash often tries to make jokes or break the tension, while Batman remains focused on the mission.

It is fascinating to compare this version to the Wally West of Justice League Unlimited :

In "The Batman," Barry Allen is portrayed as a crime scene investigator for the Central City Police Department. His origin story is similar to the comic book version: Barry gained his powers after being struck by lightning and doused in chemicals during a freak accident. Using his newfound abilities, he becomes the Flash, a superhero dedicated to fighting crime and protecting Central City.

“You’re not just fast,” Batman said, voice low. “You’re vibrating. Phasing through solid matter. That’s why no locks stop you.” Although producer Alan Burnett identified this version as

The Flash’s smirk faltered.

One of the greatest strengths of The Batman (2004) was its willingness to experiment with visual effects, utilizing heavy digital gradients, sharp angles, and stylized motion blur. The Flash was the perfect canvas for this aesthetic.

Schlatter’s vocal performance is pure kinetic energy. He delivers lines at a machine-gun pace, often breaking the fourth wall with his internal monologue spoken aloud. He is not the wise-cracking jokester of Justice League Unlimited ; he is more of a lovable, chaotic idiot savant. He forgets names, interrupts Batman mid-sentence, and shows a genuine, childlike wonder at the world.

A Flash-centric episode where a time-manipulating villain named “Clock King” (a different version than the classic one) traps the Flash in a three-second time loop. This episode is a psychological deep dive. We see the Flash alone, unable to stop, reliving the same moment. It reveals his greatest fear: not death, but boredom and isolation. Schlatter’s voice-acting here is haunting.
