Robotic Teacher of Krypton - With Bad Attitudes!

Consider two sets of orphans, separated from their advanced civilizations when their native parallel planets were destroyed. Now possessing the greatest set of powers in their respective universes, how would they be trained to control these awesome instruments that were their now superhuman bodies? 

Send in the robots! And that is what Jor-El did with the Super-Teacher. And Zor-L did something similar with his Symboship which transported his daughter from his doomed world. Both were devised with the benevolent attempt to inculcate instruction into the surviving cousins of counterpart planets Krypton.

Each possessed the ability of creating virtual realities. Symbioship itself could also replicate itself into four different vessels, with one occupying a re assimilated Kara Zor-L outside Gotham City while her cousin Kal-L was occupied with three copies hovering over his own city of Metroplis simaltaneously. These four vessels of Krypton-Two mirrored four similar vessels originating from Krypton-One, all of which contained survivors of the doomed Krypton.

Those four corresponding vessels that had arrived on Earth-One was: 1.) the vessel that carried Kara Zor-El from planetary fragment Argo City after it has been decimated by Kryptonite meteors, 2.) the Super-Teacher unit which itself was a space vessel, 3,) the experimental star craft that brought Krypto to his master Superboy (that Super-Dog’s doppelgänger Thor the Thunder Dog was constructed by alien Manhunters), 4.) the spacecraft Brainiac used to transport the captured city of Kandor shrunken in a bottle.

Zor-L's robotic intelligence needed a humanoid host to pilot it so that it became more bipedal and less vessel, which it assimilated using the body of reporter Andrew Vinson, while the Super-Teacher was fully automated on its very own in its three encounters with the Children of Steel.

Unfortunately, neither possessed the "human touch" when it came to tactful training. This caused some troubles for a young Superboy and, later, Supergirl, when Super-Teacher challenged both kids and left both of them with hard feelings towards the automaton.

For Kara Zor-L aka Power Girl, she was fed up with the exhaustive training of the Symbioship and its attempt to reclaim her by using the human body of her soon-to-be friend Andrew Winston, so she ended up destroying it.

However, Power Girl can thank her ship's inner mechanism for providing her with a virtual reality template of Kandor which included its residents.

Occupants of this synthetic Kandor included her parents and others who lived when Krypton-Two still existed, long after the real city they were based on had expired. It could not take the place of the real thing, which her counterpart Kara Zor-El had when she found the real Kandor-One trapped in a bottle, but was a reliable simulation of it.

However, just as shrunken Kandor of Earth-One survived into the modern day, so too had the cybernetic Kandor on Earth-Two. Both cities' inhabitants resided in other dimensions of Rokyn and Dream Dimension respectively. Later, Rokyn shifted into "another universe", and the closest universe to Earth-One is Earth-Two. So from time to time, other Kryptonians besides Kal-L and Kara Zor-L resided in their realm during the 1980s and beyond!

Not to mention her parents Zor-El and Allura, who were trapped in the Survivor Zone for several years. But then, that's another story.
