Ah Choo is the son of Ah Men and the grandson of Ah Huy, and immigrated to America from an unnamed town in China. In the early 1940's, he worked at Vaughn's Pharmacy in a large, coastal California city, alongside Stormy Foster. Very often he involved himself in adventures of The Great Defender, a local super hero.
- This version of Ah Choo, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
- Comic book stories from the 1940s may depict some ethnic and racial prejudices that were once commonplace in American society. Such depictions were wrong then and are wrong today. While not representing the DC Comics view of today's society, these stories are being indexed and summarized as they were originally created, because to do otherwise would be the same as claiming these prejudices never existed.
