"The SUPER-TEACHER from KRYPTON!"

[VanZee]

Odd story.  The teacher didn't teach the student a doggone thing the student didn't already know and caused a lot of Mxy-like trouble in the process.  Not much of a payoff in this "morality play," but still a fun read.

Funny that lonely Superboy would allow this piece of property, with direct knowledge of and unlimited information on his family and his home world to fly off elsewhere.  Super-Teacher is almost like a lost uncle.  What a trophy for the Fortress!  Does anyone know if this character ever returned in later stories?

[ShinDangaioh]

Yes.  To test Supergirl

As to being a piece in the Fortress, Superboy didn't have build it yet.

Please don't flame me for this, but the thought just occurred to me.  Is it possible that this robot teacher wasa partial inspiration for the Post-Reboot Eradiacator?  I never cared for this "character", but the Eradiacator also possessed the knowledge, traditions and lore of "his" Krypton.

Does anyone know if this character ever returned in later stories?

Yes. Super-Teacher returned to test Superboy again. This time Superboy was much older and on the verge of becoming Superman. It's a really good story. I think it first appeared in DC Super-Stars #12 (1977).

The teacher manipulates Superboy into a murderous rage. Superboy completely loses his temper and wants to kill.

How many inventions did Jor-el make before Krypton was destroyed?

It seems like he had a long time between discovering Krypton was going to explode and when it finally did.

In that time he sent out several prototype ships. Built a robot teacher for his son that would somehow know about superpowers and how to use them. Started work on a space ark to save the Kryptonians which was taken away with Kandor.

Anybody know how long he had to accomplish all of this?

This might help you. It's the World of Krypton, the story of Superman's father Jor-El.
