Johnny Thunder's Ex-Partner

When Black Canary first started, way back in 1947, her first few efforts were in conjunction with Johnny Thunder and his Magic Thunderbolt. Johnny commanded this thunderbolt when he said the magic phrase "Cei-U" (phonetically "Say you"). Black Canary just knew judo and how to stay out of sight.

But the thunderbolt didn't respect Johnny, who was a little on the dim side, and would often fulfill Johnny's command literally instead of as Johnny meant it, just to spite him. This led to seven years worth of comic mix-ups, such as we see here. Johnny was in the middle of a mystery and just happened to mutter "Say, you know, it would be nice if Black Canary got roped into this case".

Now Johnny and the thunderbolt are "discussing" semantics while Black Canary seriously considers going solo from now on.
