"H-He didn't even kill me!"
I want to scan all of these loose stories to preserve them in a digital form, because they aren't gonna last much longer in their printed state. "Bombshell" is from the first issue of Lev Gleason's Boy Comics, April, 1942, numbered #3. Boy Comics was continued from the first two issues of Captain Battle.
The story was written by Dick Wood, brother of Bob Wood, co-editor with Charles Biro of Boy Comics. It's drawn by someone named "Michael," an artist unfamiliar to me. As near as I can tell from checking the Grand Comics Database, Bombshell was a short-lived hero, lasting only four issues. I think the concept had as much promise as any of the rest of the characters in the book. Except considering he comes from another planet Bombshell seems to be an all-American boy, and his sword can't kill anybody, even Hitler. C'mon…what fun is that?
