The Complete List of Kryptonians (Official)

[Dylan Clearbrook]

Wasn't Dev-Em the juvenile next door neighbour to Jor-El who eventually ended up in the Phantom Zone

The link in my previous post gives a good account of Dev-Em.  

I don't know if he has shown up in post crisis continuity yet.

Dev-Em was recast as a Daxamite the Post-Crisis Legion tales (I believe first reappearing during the Five Year Gap Legion), though he worked with the United Planets' Interstellar Counter-Intelligence Corps rather than the Legion.  He disappeared in Zero Hour and apparently has not been revived since.

Somewhere in that period of time, he went nuts and tried to blow up the moon during Time and Time Again.

[Jor-El]

Hmmmm were any of the Vathlo citizens ever imprisoned in the Phantom Zone

[Bill 9000]

Is this supposed to be a Pre-Crisis or Post-Crisis list?

[Super Monkey]

considering what site this is, I would say Pre-Crisis

[Jor-El]

Yes a pre-crisis list
If it was a Post Crisis list, it could include

Van-L
Vara
Nara
Seyg-El - Jor-Els father - love the injoke
But then again there wasn't anything particularly memorable about Byrne's Krypton except it was inspired by the movies and had its own Clone Wars
