I have a bit of an idea.

I think Clark used the name Charlie King, right?
And Lois has used Lola Dane and Wanda Detroit?

Are there any other names they used or mentioned using that I'm forgetting?

Thanks,

Spike and Angel in Resurrection. But Wanda Detroit wasn't one of Lois's undercover identities. More like an alternate personality.

Oh I know she didn't use Wanda as an undercover name, but I'm including it anyway. I might use it for the story I have an idea for. I forgot about Spike and Angel though... they might take my story in a different direction than planned...

I keep expecting someone to use the Spike and Angel coincidence (if that's what it was) for a Buffy crossover...

Lois also used Larry

It was a coincidence. Buffy (the TV show) aired first in 1997, Resurrection was in 1995.

In Wall of Sound Lois used 'Linda'.

In "The Source" she was Miss Jefferson...
